Abstract: A display apparatus, comprising: a plurality of light sources arranged into an array, angle selection sheets on the light emitting sides of the light sources, and reflective layers on the sides of the light sources away from the angle selection sheets. The angle selection sheets are used for reflecting light rays of a first incident angle range and transmitting light rays of a second incident angle range, wherein an incident angle value corresponding to the first incident angle range is smaller than an incident angle value corresponding to the second incident angle range. The reflective layers can conduct diffuse reflection on the light rays reflected by the angle selection sheets and the light rays re-enter the angle selection sheets, so that light rays of a second incident angle subjected to the diffuse reflection are transmitted while light rays of a first incident angle repeat the described reflection operation.
