Light-emitting unit, light-emitting device and display device

Abstract

This application relates to the field of display technology, and discloses a light-emitting unit, including: a light-emitting semiconductor, including a first semiconductor layer, an active layer, and a second semiconductor layer stacked in sequence, and a recessed structure, wherein the recessed structure includes a recessed The top and the bottom of the depression, the bottom of the depression or the top of the depression is located in the first semiconductor layer; the first electrode includes a first part and a second part; wherein the first part is arranged on the first semiconductor layer; The second part is arranged on the side of the light-emitting unit, and the second part includes a light-isolating material. The display device provided by the present application avoids the transmission of the light emitted by the light-emitting units to each other as much as possible, and prevents the light crosstalk between the light-emitting units as much as possible, which is beneficial to improve the display effect, and also simplifies the structure of the display device. The application also discloses a light emitting device and a display device.

Description
