Abstract

A display device having a plurality of light-emitting elements that construct picture elements aligned on a TFT substrate in a formation of a matrix. The display device includes the plurality of light-emitting elements each having a flat surface portion and including a light-emitting layer, an anode, and a cathode; a plurality of driver elements each coupled to the light-emitting element; a plurality of capacitor elements each of which is coupled to the light emitting element and receives an image signal; a plurality of switching elements each of which is coupled to the capacitor element and the light emitting element and control input of the image signal to the capacitor; and an insulation layer having a contact hole formed over the driver element. The anode is formed on the insulation layer and coupled to the driver element via the contact hole.
