Abstract

The present application provides a display panel and a display device, wherein the display panel includes: a planarization layer; a pixel definition layer, formed on the planarization layer and defining a plurality of pixel regions; an anode layer and an organic layer, sequentially formed on the planarization layer The cathode layer is formed on the pixel definition layer and the organic layer; wherein, a plurality of grooves are formed on the contact surface of the pixel definition layer and the cathode layer, and the plurality of grooves are arranged at intervals. Pixels define layer conformal settings. Therefore, the cathode layer also has a groove structure, which has a certain anti-reflection effect on the ambient light entering the company, thereby reducing glare and improving display contrast.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] At present, when the external light shines on the metal electrodes of the OLED device, it will produce obvious reflection phenomenon, resulting in the glare of human eyes, the reduction of color saturation, and the reduction of display contrast. The influence caused by the display of the device is usually attached to the outer layer of the OLED device with a polarizer to reduce glare and improve the display contrast. [0003] The traditional polarizer has high reflectivity. When the polarizer is directly made on the screen by coating, the reflectivity of the screen is still high, which cannot fully meet the needs of use. SUMMARY OF THE INVENTION [0004] The present application provides a display panel and a display device to solve the problem of low display contrast caused by the reflected lig...
