DISPLAY PANEL AND DISPLAY DEVICE

WIPO Patent Application WO/2023/225805

A1

A display panel and a display device. The display panel comprises a display substrate (PNL), a filter structure (CL), and a cover plate (CG). The display substrate (PNL) is provided with a plurality of light emitting devices (LD) distributed in an array. The filter structure (CL) is arranged on one side of the display substrate (PNL); at least a part of the filter structure (CL) comprises a filter layer (CF), a lens layer (Lens) and a filling layer (FL); the lens layer (Lens) is located on the side of the filter layer (CF) away from the display substrate (PNL), and is provided with a first light-transmitting hole (HCL); the side wall of the first light-transmitting hole (HCL) expands in a direction away from the display substrate (PNL); the filling layer (FL) fills the first light-transmitting hole (HCL), and the refractive index of the filling layer (FL) is greater than the refractive index of the lens layer (Lens) where the first light-transmitting hole (HCL) filled with the filling layer (FL) is located. The cover plate (CG) is arranged on the side of the filter structure (CL) away from the display substrate (PNL). The display panel is used for improving brightness without increasing power consumption.
