Abstract
An organic light emitting display device is disclosed, which prevents non-uniform luminance and color deviation caused by a change of a viewing angle from occurring. The organic light emitting display device includes a first substrate having a display area and a non-display area; an organic light emitting diode arranged in the display area of the first substrate; and an anisotropic diffusion film arranged on the organic light emitting diode, having a diffusion property varied depending on an incident angle.
