Organic light emitting diode device
An organic light emitting diode device includes an organic light emitting display panel and a circular polarizing plate which includes a polarizer and a compensation film including a liquid crystal layer which includes a first surface and a second surface, and liquid crystals that tilt obliquely with respect to an extension direction of the first and second surfaces of the liquid crystal layer where tilt angles of the liquid crystals with respect to the extension direction of the liquid crystal layer become gradually larger from the first surface to the second surface of the liquid crystal layer in a thickness direction of the liquid crystal layer, and a maximum tilt angle of the liquid crystals with respect to the extension direction of the liquid crystal layer is determined based on a thickness direction phase delay generated in a thickness direction of the organic light emitting display panel.
