Abstract:
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, an anode and a cathode; a driver element connected with 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 connected to the driver element via the contact hole; and 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 against the flat surface portion of the light-emitting device; wherein the tilted reflective 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 reflective surface on the light emitting device; and wherein the optical waveguide layer is optically isolated from each of the picture elements.
