Abstract
In a display device including a light-emitting element layer formed on a thin film transistor layer, the light-emitting element layer includes pixel electrodes, a cover film, a light-emitting layer, and a common electrode. The pixel electrodes each include a flat first portion overlapping with the light-emitting layer and a second portion surrounding the first portion. The first portion protrudes toward the light-emitting layer compared to the second portion. The cover film covers the second portion and causes the first portion to expose. An upper face of the first portion and an upper face of the cover film form a flush planar face.
