Abstract:
1. A display device, comprising: a substrate; an underlying layer being a pixel electrode formed to extend over the substrate; an insulating layer formed over the substrate to expose the underlying layer and to contain a recess; and an organic EL layer laser transferred onto the exposed portion of the underlying layer and formed only within the recess to be not higher than the insulating layer, so that an end of the organic EL layer is formed on at least a sidewall of the insulating layer and is separated from the underlying layer by an edge of the insulating layer that intrudes between the organic EL layer and the underlying layer, wherein a thickness of the insulating layer is greater than zero and is less than 500 nm, and the organic EL layer is formed on the insulating layer so that a thickness of the organic EL 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 EL layer formed on the underlying layer.
