Abstract

The invention discloses a display panel and a display device, and belongs to the technical field of display. The display panel comprises a substrate, a counterpoint electrode layer and a first planarization layer, wherein the counterpoint electrode layer comprises a plurality of counterpoint electrode groups, each counterpoint electrode group at least comprises a first counterpoint electrode and a second counterpoint electrode, a plurality of grooves are formed in the side, away from the substrate, of the first planarization layer, one light-emitting element is arranged in one groove, and the light-emitting elements can rotate in the grooves in the direction parallel to the plane where the substrate is located. The display device comprises the display panel. According to the invention, the situation that the positions of light-emitting elements are changed after alignment is completed to affect the subsequent process and the display effect can be avoided, the redundant light-emitting elements can be recovered after alignment is completed, the light-emitting elements are uniformly distributed on a substrate as much as possible, and the display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Light emitting elements (such as light emitting diodes, LEDs) have high light conversion efficiency, very low energy consumption and are semi-permanent and environmentally friendly. Therefore, LEDs are used in many fields, such as traffic lights, mobile phones, car headlights, outdoor electronic bulletin boards, backlights and indoor / outdoor lights, etc., so that products using LED displays have self-illumination, high brightness and luminous efficiency, Low power consumption, high stability and other advantages, are widely used in various occasions. [0003] With the reduction of LED chip size and pixel pitch, LED display is expected to realize flexible, highly transparent, interactive and modular splicing display, which is considered to be a revolutionary display technology with full function...
