Claim:
1. A display device comprising: a plurality of pixels on a substrate including an insulating surface, each of the plurality of pixels including: a transistor above the insulating surface; a planarization film covering the transistor; a pixel electrode above the planarization film and electrically connected with the transistor; a bank layer above the planarization film and below the pixel electrode; an insulating layer in a recess located around the pixel electrode between the pixels adjacent to each other; a light-emitting layer covering a surface of the pixel electrode and at least a part of a surface of the insulating layer; and a counter electrode above the light-emitting layer, wherein the bank layer includes a top surface and a side surface, the pixel electrode covers the top surface and at least a part of the side surface of the bank layer, the recess is surrounded by the side surface of the bank layer, and a distance between a surface of the substrate and a face of the light-emitting layer in contact with the insulating layer is equal to or smaller than a distance between the surface of the substrate and a face of the light-emitting layer in contact with the pixel electrode.
