Abstract:
1. A display device, comprising: a substrate; an underlying layer being a pixel electrode formed to extend on the substrate; an insulating layer formed on the substrate to expose a portion of the underlying layer; and an organic electroluminescent layer formed on and in contact with the exposed portion of the underlying layer, and having an end that is separated from the underlying layer by an edge of the insulating layer that intrudes between the organic electroluminescent layer and the underlying layer, wherein the end of the organic electroluminescent layer is formed on at least a sidewall of the insulating layer and is not higher than the insulating layer, the insulating layer is greater than zero and is less than 380 nm thick, and the organic electroluminescent layer is formed on the insulating layer so that a thickness of the organic electroluminescent layer that is formed over the edge and the sidewall of the insulating layer, and separated from the underlying layer, is the same as a thickness of the organic electroluminescent layer formed on the underlying layer.
