[claim 10] The electroluminescent display device of claim 9, wherein the cathode is disposed in the additional trench (fig. 25), the cathode being absent at the portions of the additional trench within the laser ablation area (fig. 25). [claim 11] The electroluminescent display device of claim 1, wherein the laser ablation area is an area from which the cathode and the organic layer are removed by irradiating a laser to a portion of the upper side of the non-active area [0708]. [claim 12] The electroluminescent display device of claim 3, further including a passivation layer (109,111, fig. 25) over the cathode, wherein the passivation layer extends to an end portion of the substrate in the non-active area (fig. 25), and wherein the passivation layer is in the trench (111 is in the trench, fig. 25). [claim 13] The electroluminescent display device of claim 5, wherein the laser ablation area is spaced apart an edge of the substrate (fig. 24). [claim 14] The electroluminescent display device of claim 1, wherein the dam surrounds the active area on a plane view (fig. 2A/2B/2C/2D). [claim 16] An electroluminescent display device (figs. 24, 25), comprising: a substrate (100, fig. 24) including an active area (EA, fig. 24) and a non-active area (CA, fig. 24) surrounding the active area; an anode (PE, fig. 24, [0544]) over the substrate in at least the active area; an organic layer (ED, fig. 24, [0550]) on the anode in at least the active area; and a cathode (CE, fig. 24) on the organic layer in at least the active area; an encapsulation substrate (108, fig. 24) above the substrate; an adhesive layer between the substrate and the encapsulation substrate ([0591] discloses an adhesive layer between the encapsulation substrate 108 and the substrate 100, fig. 24), the adhesive layer contacting the encapsulation substrate (fig. 24) wherein a laser ablation area (LPP, fig. 25) is defined in the non-active area to surround the active area, wherein each of the organic layer and the cathode are absent in the laser ablation area (CE and ED are absent from LPP, fig. 25), and wherein at least one of the organic layer and the cathode is disposed in the non-active area outside of the laser ablation area (in the dam area 105, fig. 25), and a dam (105, 101d, 109, fig. 25, [0560]) in the laser ablation area between the substrate and the encapsulation substrate, wherein the dam contacts the encapsulation substrate (fig. 24).

Response to Arguments Applicant’s arguments have been considered but are moot because the new ground of rejection does not rely on any interpretation applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
