Claim Text:
1. A display device comprising: a plurality of light-emitting elements aligned on a TFT substrate in a formation of a matrix, the plurality of light-emitting elements each having a flat surface portion and including an anode, a light-emitting layer arranged on the anode, and a cathode arranged on the light-emitting layer; an insulation layer formed on the TFT substrate and under the light emitting element; and a tilted metal is provided on a peripheral area surrounding the flat surface portion of the light-emitting element and has a tilt angle against the flat surface portion of the light-emitting element; wherein the tilted metal is provided on a surface of a slope of a bank that is provided on the insulation layer, wherein a width of a cross section of the bank becomes smaller as the cross section comes farther away from a surface of the TFT substrate, wherein a counter substrate is placed on the plurality of light-emitting elements, the tilted metal, and the TFT substrate, wherein the light emitting element emits light in a direction from the TFT substrate to the counter substrate, and wherein gap exist between the light emitting element and the counter substrate.
