Abstract:
1. An organic light emitting diode (OLED) display device, comprising: a first substrate; a second substrate disposed spaced apart from and opposite to the first substrate; a first electrode positioned on the first substrate; an organic light emission layer positioned on the first electrode; a second electrode positioned on the organic light emission layer; and an entirely amorphous capping layer positioned on the second electrode to cover the organic light emission layer, said capping layer comprising an ultraviolet (UV) interception material intercepting UV rays irradiated to the organic light emission layer from an exterior of the OLED display device, wherein the capping layer is deposited by the atom or by the molecule, and the capping layer comprises one or more of a-NPD, NPB, TPD, m-MTDATA, Alq3, or CuPc.
