Organic light emitting display device

An organic light emitting display device comprising:

• a substrate;
• a first pixel electrode disposed on the substrate;
• a pixel defining film disposed on the first pixel electrode and having a first opening at least partially exposing the first pixel electrode;
• a first organic light emitting layer disposed on the pixel defining film and overlapping with the first opening of the pixel defining film;
• and
• a black matrix disposed on the first organic light emitting layer and having a first opening overlapping with the first organic light emitting layer, wherein
• the first opening of the black matrix has a smaller area than the first opening of the pixel defining film, and
• the first opening of the black matrix has a circular shape which is composed of assemblies of dots that are spaced a same distance apart from a virtual center point of the first opening of the black matrix.

• light having passed through the first opening of the black matrix is one of red light, green light, and blue light, and
• the first opening of the black matrix has a circular shape or a non-elliptical polygonal shape similar to a circle which is composed of assemblies of dots that are each spaced apart from a center point of the opening at a distance defined by the center point of the first opening and a circular or polygonal shaped perimeter of the first opening.
