Abstract: A light source module includes a light source and a reflective element. The light source has a light emitting surface. The reflective element is disposed on a transmission path of an illumination light beam emitted from the light source. The illumination light beam reflected by the reflective element is irradiated on a target plane. The reflective element includes a first reflective surface and a second reflective surface. The first reflective surface is disposed towards the light emitting surface of the light source, and is a plane. The second reflective surface bendably extends from the first reflective surface.

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.

Abstract: A light source module includes a light guide plate, a first light source, multiple first optical microstructures, and multiple second optical microstructures. The first light source is disposed on a side of a first light incident surface of the light guide plate. The first and second optical microstructures are disposed on a bottom surface of the light guide plate, and respectively located in a first and a second zone. A first light receiving surface of each first optical microstructure facing the first light source has a first edge connecting the bottom surface, and a perpendicular bisector of the first edge passes through the first light source. The first zone does not overlap the second zone. A second light receiving surface of each second optical microstructure has a second edge connecting the bottom surface, and a perpendicular bisector of the second edge does not pass through the first light source.
