Abstract

The embodiment of the invention discloses a display panel, a display device and a manufacturing method of the display panel. A display panel, comprising: at least one light emitting diode chip, the light emitting diode chip including a first electrode and a first semiconductor layer stacked; a conductive layer located on a side of the light emitting diode chip away from the first electrode; the The conductive layer is in contact with the first semiconductor layer; the conductive layer includes a hollow part, and along the thickness direction of the first semiconductor layer, the projection of the hollow part on the conductive layer is the same as that of the first electrode on the The projections on the conductive layer overlap. The embodiments of the present invention achieve the effect of reducing the resistance of the current conduction layer with relatively low process difficulty on the basis of ensuring the light extraction rate of the display panel.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a display device, and a method for manufacturing the display panel. Background technique [0002] Micro Light Emitting Diode (micro-LED / μLED) display panels integrate light emitting diode (Light Emitting Diode, LED) chips with a size of less than 100 microns on a substrate as display pixels to realize image display. Each display pixel can be addressed and individually driven to light up, so the Micro-LED display panel is a self-illuminating display panel. [0003] In the prior art, the LED chip adopts the solution of the current conduction layer to realize the common cathode connection, and the current conduction layer conducts and distributes the current conduction to each LED chip (pixel) in the display area. However, the existing common cathode connection scheme has the problems of uneven current distribution and poor brightnes...
