Abstract:
1. An organic light emitting diode display device, comprising: a substrate main body; a plurality of organic light emitting diodes formed on the substrate main body, each one of the plurality of organic light emitting diodes comprising a first electrode, an organic emissive layer formed on the first electrode, and a second electrode formed on the organic emissive layer; and a differential capping layer of different thickness covering the plurality of organic light emitting diodes, wherein the differential capping layer comprises first regions having an even thickness and second regions with another even thickness different from the thickness of the first regions, and the first regions correspond to the organic light emitting diodes emitting having a first color and the second regions correspond to the organic light emitting diodes emitting light having at least two colors different from the first color.
