ABSTRACT:
An organic light emitting display apparatus includes a first substrate, a plurality of organic light emitting pixels formed on the substrate, a second substrate bonded to the substrate to seal the organic light emitting pixels. A black matrix layer is formed on a surface of the second substrate facing the first substrate and provides a plurality of openings. One of the openings and one of the pixels are aligned. The pixel has a first edge and a second edge and the opening has a first edge and a second edge. The first edge of the pixel is closer to the first edge of the opening than the second edge of the opening. The two edges of the opening are interposed between the two edges of the pixels when viewed from a direction perpendicular to the surface. Where L is an imaginary straight line passing the first edge of the pixel and the second edge of the opening in an imaginary plane perpendicular to a direction in which the edges extend, the imaginary line L and the first surface form an acute angle which is greater than about 30° and smaller than about 45°.
