Problems solved by technology

[0004] However, when the light-emitting element emits light, due to the different distances between each position of the light-emitting element and its light-emitting layer, the luminous efficiency of different regions of the same light-emitting element is different, thereby affecting the display uniformity of the display panel; at the same time, due to the same The luminous efficiency of different regions of the light-emitting element is different, so that the light-emitting element cannot accurately present the corresponding luminous brightness, which is not conducive to the further improvement of the contrast of the display panel

Abstract

The invention discloses a display panel and a display device. The display panel includes: a substrate; a light emitting element on the substrate; the light-emitting element comprises a first electrode and a light-emitting layer; in the direction perpendicular to the plane where the substrate is located, the light-emitting layer and the first electrode are not overlapped; the light absorption layer is positioned on one side, deviating from the substrate, of the light-emitting element; the light absorption layer comprises a plurality of opening structures and light absorption parts located among the opening structures; in the direction perpendicular to the plane where the substrate is located, the light absorption part is overlapped with the first electrode, and the opening structure is overlapped with the light emitting layer. According to the embodiment of the invention, the display uniformity of the display panel can be improved, and the high-display light-emitting requirement of the display panel can be met.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, the requirements for the display function of the display device are getting higher and higher. The light-emitting panel with the characteristics of good luminous brightness, high luminous efficiency, wide viewing angle range and self-illumination has become the focus of current research and application in the field of optoelectronic display. . [0003] Existing self-luminous display panels generally include a plurality of light-emitting elements, and the light-emitting elements generally include an anode, a cathode, and a light-emitting layer. By applying corresponding electrical signals to the anode and cathode of the light-emitting element respectively, the light-emitting layer is provided with corresponding carriers, namely holes and electrons, and the...
