Patent ID: 8921837

Claim:
An organic light emitting display device, comprising: a first substrate and a second substrate comprising a plurality of pixels; a thin-film transistor formed on the first substrate; a first insulating layer formed on the first substrate including the thin-film transistor; a color filter layer formed on the first insulating layer in a pixel region; a second insulating layer formed on the first substrate including the color filter layer; a light compensation layer formed on the second insulating layer and made of a material without hydrogen, wherein the light compensation layer comes into contact with a pad of a drain of the thin-film transistor; a plurality of holes formed on the light compensation layer to expose the second insulating layer therethrough to discharge foreign substances, wherein the holes are formed in an outer wall of each pixel regions; a pixel electrode formed on the light compensation layer of each pixel region; an organic light emitting unit formed on the pixel electrode to emit light; and a common electrode formed on the organic light emitting unit, wherein the light compensation layer is made of material having a refractive index of 1.5-2.7 to refract the light from the color filter layer.
