Abstract
A display panel includes an AMOLED light-emitting board and a light filter layer disposed on a cathode surface of the AMOLED light-emitting board. The light filter layer includes a color light filter and a diffusion film. The color light filter includes a red light filter component, a green light filter component, a blue light filter component, and a BM. The diffusion film is disposed on a surface of the color light filter, or is disposed on each light filter component in the color light filter. The diffusion film is configured to enable ambient light passing through the diffusion film to be incident on the cathode surface of the AMOLED light-emitting board in a direction that is not perpendicular to the cathode surface of the AMOLED light-emitting board.
