The present invention provides an organic light emitting diode display device, having a transparent substrate; a plurality of anodes on the transparent substrate; an organic functional layer on the transparent substrate, wherein the transparent substrate covers the anodes; a light-absorbing layer on the organic functional layer, wherein the light-absorbing layer is an organic material layer and the organic material layer is doped with at least a metal; and a plurality of cathodes on the light-absorbing layer. The light-absorbing layer of the present invention can effectively reduce the amount of the reflected light, thereby raising the contrast ratio and enhancing the recognition ability of the display device.

Organic light emitting didode display device having light-absorbing layer

An organic light emitting diode (OLED) device. The OLED device comprises a transparent substrate, a plurality of anodes, an organic functional layer, a black layer and a plurality of cathodes. The anodes are positioned over a transparent substrate. The organic function layer is positioned over the transparent substrate covering the anodes. The black layer is positioned over the organic functional layer and the cathodes are positioned over the black layer. Through the black layer, the amount of back reflection of external light is reduced and the contrast of the display device is increased.
