More Information
Summary:An organic light-emitting display apparatus includes a substrate including a plurality of red, green, and blue sub-pixel regions, a pixel electrode in each of the plurality of the red, green, and blue sub-pixel regions on the substrate, a Distributed Bragg Reflector (DBR) layer between the substrate and the pixel electrodes, a high-refractive index layer between the substrate and the DBR layer in the blue sub-pixel region, the high-refractive index layer having a smaller area than an area of a corresponding pixel electrode in the blue sub-pixel region, an intermediate layer including an emissive layer on the pixel electrode, and an opposite electrode on the intermediate layer.
