DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2022/246906
Kind Code:
A1
Abstract:
A display panel. The display panel comprises an array substrate (10) and an anode layer (20) provided on the array substrate (10); the anode layer (20) comprises a first conductive layer (21) and a second conductive layer (22) located above the first conductive layer (21); the surface of the first conductive layer (21) facing the second conductive layer (22) is provided with a first grating structure; the first conductive layer (21) is a light-reflecting conductive layer; the second conductive layer (22) is a light-transmissive conductive layer; and a light emitting layer (30) is provided on the second conductive layer (22). By providing the first grating structure on the first conductive layer (21), the present application weakens a surface plasmon effect and a waveguide effect occurring in a dielectric layer near an anode, reduces the amount of light consumed by the two effects, and improves the light emitting efficiency of the display panel.
