Patent ID: 7898175

Claim:
An organic light emitting display apparatus comprising: a substrate; a display device formed on the substrate, the display device comprising a plurality of organic light emitting pixels, wherein each pixel is spaced from an immediately neighboring pixel by a non-light emitting area; a sealing member bonded to the substrate such that the organic light emitting pixels are interposed between the substrate and the sealing member; and a black matrix formed on a surface of the sealing member facing the substrate and overlapping with the non-light emitting area when viewed in a first direction perpendicular to the surface, wherein a first one of the organic light emitting pixels overlaps with the black matrix when viewed in the first direction, wherein a is a width of the first pixel, wherein b is a width of a first area of the first pixel overlapping with the black matrix, wherein the width a and the width b are measured in a second direction parallel to the surface, wherein t 2 is a distance between the sealing member and the first pixel, wherein the black matrix and the first pixel are arranged so as to satisfy the following relationship: a −√{square root over (3)}×t 2 ≦b≦a−t 2 ; and wherein the distance between the substrate and the sealing member is about 5 to about 20 μm.
