Abstract
A display device includes a plurality of sub-pixels, a support body, a thin-film-transistor layer, a light-emitting-element layer, and a sealing layer. The thin-film-transistor layer includes a plurality of thin-film transistors and a planarization film. The light-emitting-element layer includes a plurality of light-emitting elements. Each of the plurality of light-emitting elements includes a lower electrode, a functional layer, and an upper electrode. The lower electrode is a sub-pixel electrode shaped into an island and provided for each of the sup-pixel electrodes. The upper electrode is a common electrode formed in common among all the plurality of sub-pixels. The planarization film includes a trench shaped into a frame and provided for each of the sub-pixels. The trench defines a light-emitting region of the light-emitting element for each of the sub-pixels.
