Abstract: A display device, including a display module and a peep-proof light source module, is provided. The display module is used to provide a display beam. The peep-proof light source module is disposed on a transmission path of the display beam and includes at least one light emitting element, a light guide plate, and optical microstructures. The light emitting element is used to provide a privacy light. The light guide plate has at least one light incident surface. Each optical microstructure has an optical surface facing the light incident surface. At least part of the privacy light is reflected by the optical surface and then exits the light guide plate. The distribution density of the optical microstructures on the light guide plate close to the light incident surface is substantially the same as the distribution density away from the light incident surface and close to the center.
