Description

A display panel and a display device technical field [0001] The present application relates to the field of display, in particular to a display panel and a display device. Background technique Organic light-emitting diodes (Organic Light Emitting Diode, OLED) have ultra-thin, self-luminous, visual It has the advantages of wide angle, fast response, low power consumption and flexible display. Since the advent of the first generation of organic fluorescent small molecule OLEDs, the efficiency and lifespan of OLEDs have been significantly improved. High, the theoretical internal quantum efficiency of the first generation fluorescent OLED can reach 25%, and the subsequent phosphorescence and the theoretical internal quantum efficiency of TADF luminescent materials. The quantum efficiency is even 100%. However, due to the mismatch between the refractive index of the metal layer and the organic layer of the OLED device and the It does not match the refractive index of a...
