Light-emitting display device and method of manufacturing the same

摘要

A light-emitting display device includes a substrate having a plurality of pixels. A first electrode is provided on the substrate for each pixel, and a pixel defining layer defines each of the pixels. The pixel defining layer has an opening to expose the first electrode. A charge injection layer is on the first electrode, and a surface processing layer is on the charge injection layer. The surface processing layer extends from inside the opening of the pixel defining layer to a top surface of the pixel defining layer. The surface processing layer including a plurality of grooves in a portion extending on the top surface of the pixel defining layer. A charge transport layer is on the surface processing layer, a light-emitting layer is on the charge transport layer, and a second electrode is on the light-emitting layer.
