Abstract
A display device is formed such that pixels that each include a light emitting element formed by stacking an upper electrode, a light emitting unit, and a lower electrode are arranged in a two-dimensional matrix. The light emitting elements are formed by forming the upper electrodes which are light-transmissive, and then sequentially stacking, onto the upper electrodes, the light emitting units and the lower electrode which is formed from a metal material.
