Abstract

Provided is a display device including a substrate and multiple display pixels on the substrate. Each display pixel includes a light emitting unit and an insulating layer. The light emitting unit includes a first ohmic contact metal, a light emitting diode, and a second ohmic contact metal that are disposed in sequence in a direction away from the substrate. The insulating layer is disposed on at least a side of the light emitting diode, and includes a first protruding portion, where a distance between the first protruding portion and the substrate is greater than or equal to a distance between a top surface of the light emitting diode and the substrate. A part of the second ohmic contact metal is disposed on a first side wall of the first protruding portion facing the light emitting diode.

Claims11

Dependent claims

A display device, comprising a substrate and a plurality of display pixels disposed on the substrate, each of the display pixels comprising:

a light emitting unit, comprising a first ohmic contact metal, a light emitting diode, and a second ohmic contact metal disposed sequentially in a direction away from the substrate, wherein the first ohmic contact metal and the second ohmic contact metal are respectively connected to the light emitting diode;
and
an insulating layer, disposed on at least one side of the light emitting diode, comprising a first protruding portion, wherein a distance between the first protruding portion and the substrate is greater than or equal to a distance between a top surface of the light emitting diode away from the substrate and the substrate, wherein
a part of the second ohmic contact metal is disposed on a first side wall of the first protruding portion facing the light emitting diode.
