Abstract:
1. An organic light emitting diode display device, comprising: a substrate; a functional layer positioned on the substrate, configured to produce constructive interference of lights transmitted from the outside, wherein the functional layer comprises a first semi-transmissive layer, a second semi-transmissive layer and a transmissive layer interposed between the first and second semi-transmissive layers, wherein the thickness of the transmissive layer is greater than the thickness of the first semi-transmissive layer and greater than the thickness of the second semi-transmissive layer, and wherein the first semi-transmissive layer and the second semi-transmissive layer comprise an identical material; a first electrode positioned on the functional layer; an organic emission layer positioned on the first electrode; and a second electrode positioned on the organic emission layer.
