Light-emitting element and display device using same

摘要

A display device having a plurality of light-emitting elements that construct picture elements aligned on a substrate in a formation of a matrix. The light-emitting element includes a light-emitting device having a flat surface portion and including a light-emitting layer and an anode. A driver element is connected with the light-emitting element, and an insulation layer having a contact hole formed over the driver element. The anode is formed on the insulation layer and is connected to the driver element via the contact hole. A tilted reflective surface is provided in a peripheral area surrounding the flat surface portion of the light-emitting device and has a tilt angle with respect to the flat surface portion of the light-emitting device. The tilted reflective surface is provided on a surface of a slope of a bank provided on the substrate and formed to cover the contact hole.

1. A display device having a plurality of light-emitting elements that construct picture elements aligned on a substrate in a formation of a matrix, wherein the light-emitting element comprises:
a light-emitting device having a flat surface portion and including a light-emitting layer, and at least an anode; a driver element coupled to the light-emitting element; an insulation layer having a contact hole formed over the driver element; wherein the anode is formed on the insulation layer and coupled to the driver element via the contact hole; and a tilted metal surface is provided in a peripheral area surrounding the flat surface portion of the light-emitting device, the tilted reflective surface having a tilt angle with respect to the flat surface portion of the light-emitting device; wherein the tilted metal surface is provided on a surface of a slope of a bank that is provided on the substrate; wherein the bank is formed to cover the contact hole; wherein a width of a cross section of the bank becomes smaller as the cross section comes farther away from a surface of the substrate; wherein an optical waveguide layer is overlaid in an area surrounded by the tilted metal surface on the light emitting device; and wherein a counter substrate is placed over the substrate which is formed light emitting element via gap.
