Abstract
A light-emitting element and a display device capable of improving the light emission property are provided. Each of a plurality of anode electrodes (11) is provided for a corresponding pixel. The pixel-isolating insulation film (12) has an opening (120) exposing corresponding one of the plurality of anode electrodes (11) to outside, and has an eave (123B) in the middle of a thickness direction of an inner wall of the opening (120). An organic layer (13) includes a CGL (132) cut by the eave (123B) of the pixel-isolating insulation film (12), and covers the opening (120). A cathode electrode (14) is disposed on a surface of the organic layer (13), the surface being a surface on the opposite side of the anode electrode (11).
