Abstract
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.
