Abstract:
1. A display device including a plurality of light-emitting elements aligned on a TFT substrate in a formation of a matrix, wherein the display device comprises: the plurality of light-emitting elements each having a flat surface portion and including a light-emitting layer, an anode, and a cathode; an insulating layer formed on the TFT substrate and under the light emitting element; and a tilted metal surface is provided on a peripheral area surrounding the flat surface portion of the light-emitting element and has a tilt angle with respect to the flat surface portion of the light-emitting element; wherein the tilted metal surface 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 TFT substrate; and wherein a gap exists between the light emitting element and the counter substrate.
