The light guide plate (1211) includes a light guide plate layer and a diffusion layer disposed on an upper surface of the light guide plate layer, and the diffusion layer is configured to diffusely reflect light emitted by the light emitting member (1213). The optical adhesive layer (1202) includes diffusion particles for atomizing light transmitted through the light guide plate (1211).
