Regarding claim 3, par [0178] of Won discloses further comprising a thin- film encapsulation layer disposed on the display element, wherein the thin-film encapsulation layer comprises a first inorganic encapsulation layer, an organic encapsulation layer on the first inorganic encapsulation layer, and a second inorganic encapsulation layer on the organic encapsulation layer. Regarding claim 4, par [0178] of Won necessary discloses wherein the first inorganic encapsulation layer and the second inorganic encapsulation layer contact each other in the first corner area and the second corner area (as the organic light emitting device are in those areas). Regarding claim 6, it is necessary the case that Won discloses wherein, in a cross- sectional view, the first inorganic encapsulation layer and the second inorganic encapsulation layer are spaced apart from each other in a portion of the first corner area (as the organic encapsulation layer is in between). Regarding claim 12, fig. 10A of Won discloses further comprising: a first input line SL2-1 (portion at the border of CDA1 and CDA2) disposed in the first corner area; a second input line SL2-1 (portion at the end of CDA1) disposed in the second corner area and connected to the driving circuit; and a third input line (portion of SL2-1 in between) connecting the first input line to the second input line. Regarding claim 13, Won discloses wherein each of the first input line, the second input line, and the third input line is spaced apart from the central area with the voltage supply line therebetween (see fig. 10A and fig. 15 together). Regarding claim 14, fig. 10B of Won discloses wherein the first input line is disposed in a same layer (SL layer) as the second input line and is disposed in a different layer (in layer 119 which is different) from the third input line (which is SL layer). Regarding claim 18 (see rejection of claims 3 and 5), Won discloses further comprising a thin-film encapsulation layer comprising a first inorganic encapsulation layer disposed on the display element, an organic encapsulation layer on the first inorganic encapsulation layer, and a second inorganic encapsulation layer on the organic encapsulation layer, wherein the organic encapsulation layer is disposed in the central area and the corner area, and does not overlap the driving circuit.

Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 5, 7-8 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Won. Regarding claim 5, Won discloses claim 4, but does no explicitly discloses wherein the organic encapsulation layer overlaps at least a part of the voltage supply line and does not overlap the driving circuit. However, par [0178] Because the organic light emitting device may be easily damaged by moisture or oxygen from the outside, an encapsulation layer (not illustrated) may cover and protect the organic light emitting device to protect. The encapsulation layer may include a first inorganic encapsulation layer, an organic encapsulation layer, and/or a second inorganic encapsulation layer. Note fig. 15 of Won discloses that the ELVSS in CD2 which has OLED and fig. 9A of Won disclose that driving circuit is in CDA1 without OLED. Therefore, it would have been obvious to form structure of Won wherein the organic encapsulation layer overlaps at least a part of the voltage supply line and does not overlap the driving circuit as the driving circuit does not require full protection as that of OLED from moisture. Regarding claim 7, fig. 15 of Won discloses further comprising a dam (organic encapsulation layer which a type of a dam). It would have been obvious to form the dam provided over the voltage supply line ELVSS to at least partially overlap the voltage supply line, the dam being disposed between the pixel circuit and the driving circuit (as the pixel circuit is part driving OLED need encapsulant as state in par [0178] and driving circuit does not need full protection of OLED therefore no full encapsulant as stated in par [0178]). Regarding claim 8, fig. 4A of Won discloses wherein the second corner area comprises a plurality of extending areas, and the driving circuit comprises a plurality of sub-driving circuits (it can be divide in sub parts as shown in fig. 9B showing many parts), and it would have been obvious to form a structure wherein at least one of the plurality of sub-driving circuits is disposed in each of the plurality of extending areas in order to have each WL extending area in order to supply WL signal to the pixels, and Won discloses wherein a separation area is defined between adjacent extending areas among the plurality of extending areas. Regarding claim 20 (see rejection of claim 8), Won discloses wherein the second corner area comprises a plurality of extending areas, and the driving circuit comprises a plurality of sub-driving circuits, wherein at least one of the plurality of sub-driving circuits is disposed in each of the plurality of extending areas, and wherein a separation area is defined between adjacent extending areas among the plurality of extending areas.
