Abstract:
The present invention is to provide an organic light emitting display device for preventing a thin-film transistor from being deteriorated due to hydrogen when forming a light compensation layer configured to enhance viewing angle, and the organic light emitting display device may include a first substrate and a second substrate comprising a plurality of pixels; a thin-film transistor formed at each pixel of the first substrate; a color filter layer formed at each pixel; an insulating layer formed on the color filter layer; a light compensation layer formed on the insulating layer and made of a material containing no hydrogen; a pixel electrode formed on the light compensation layer of each pixel; an organic light emitting unit formed on the pixel electrode to emit light; and a common electrode formed on the organic light emitting unit.
