Regarding claim 11, Park teaches a display device in fig. 1 and 9, wherein the display device comprises the display panel (see fig. 1) according to claim 1 (see claim 1’s rejection); the display panel (see fig. 1) comprises a plurality of first spacer layers (151/152 in fig. 9) extending in a first direction (refer to x direction) and a plurality of second spacer layers (261/262/263) extending in a second direction (refer to y direction), the first spacer layers and the second spacer layers (refer to 151/152 and 261/262/263) define a plurality of sub-pixel units (SP1/SP2/SP3/SP4/SP5/SP6), the plurality of second spacer layers (261/262/263) are configured to separate the sub-pixel units of different colors (see pars. 49 and 94), and the first direction (refer to x axis direction) is perpendicular to the second direction (refer to y-axis direction); and wherein a protrusion (refer to D protrusion) is formed on at least one of the plurality of second spacer layers (refer to 262), and the protrusion is protruded in one of the sub-pixel units (refer to SP1) (see par. 95). Regarding claim 12, Park teaches all the limitations of the claimed invention for the same reasons set forth above. Besides, Park teaches the plurality of first spacer layers (151/152) are configured to separate the plurality of sub-pixel units (SP3/SP6) located in a same row (refer to row direction that is notated below); the plurality of sub-pixel units (SP3/SP6) located in the same row have a same color (see pars. 49 and 94); and colors corresponding to the plurality of sub-pixel units (SP1/SP2/SP3 or SP4/SP5/SP6) located in a same column are arranged cyclically (NOTE: SP1/SP2/SP3 or SP4/SP5/SP6 are cyclically arranged in an order of RGB see pars. 49 and 94).

Allowable Subject Matter Claim 5 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims, since the prior art of record and considered pertinent to the applicant’s disclosure does not teach or suggest “each of the second spacer layers comprises a protruding portion and a flat portion, the protruding portion is protruded in each of the sub-pixel units, and the flat portion is connected to the second channel” in combination of all of the limitations of claim 5. Claims 6-7 include all of the limitations of claim 5. Claim 15 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims, since the prior art of record and considered pertinent to the applicant’s disclosure does not teach or suggest “each of the second spacer layers comprises a protruding portion and a flat portion, the protruding portion is protruded in each of the sub-pixel units, and the flat portion is connected to the second channel” in combination of all of the limitations of claim 15. Claims 16-17 include all of the limitations of claim 15.
