Abstract
According to an aspect of the present disclosure, an organic light emitting display device includes an organic light emitting display panel including a plurality of sub pixels, a pattern buffer layer disposed on the organic light emitting display panel and patterned so as to overlap at least one sub pixel of the plurality of sub pixels, a color filter layer disposed on the pattern buffer layer and including a plurality of color filters corresponding to the plurality of sub pixels, and a black matrix disposed on the same plane as the pattern buffer layer and dividing the plurality of color filters. Accordingly, generation and spread of cracks when the display device is folded may be effectively suppressed. Therefore, the driveability of the display panel and the reliability of the organic light emitting display device may be improved.
