ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

PURPOSE: An organic light emitting display device is provided to prevent discoloration due to a direction of a view angle by including a light compensation layer which compensates an optical path and a phase difference. CONSTITUTION: A thin film transistor is formed at each pixel of a substrate. A first insulation layer(26) with a first refractive index is formed on the thin film transistor. A light compensation layer(18) is formed on the first insulation layer. The light compensation layer has a second refractive index which is different from the first refractive index. A pixel electrode(21R,21G,21B) is formed on a pixel of the light compensation layer. An organic light emitting unit(23) is formed on the pixel electrode and emits light.
