Abstract: A lighting decoration module includes an LGP, at least one light source, and first and second optical microstructures. The LGP has at least one light incident surface and first and second light exit surfaces that are opposite to each other and connect the light incident surface. The light source corresponds to the light incident surface. The first optical microstructures are disposed on the first light exit surface and each has a first surface facing the light source. A first angle between the first surface and the first light exit surface is within a range from 40-60 degrees or 15-35 degrees. The second optical microstructures are disposed on the second light exit surface and each has a second surface facing the light source. A second angle between the second surface and the second light exit surface is within a range from 40-60 degrees.

Abstract: An anti-peep light source module and an anti-peep display device having an anti-peep function and good image quality are provided. The anti-peep light source module includes a light guide plate, a first light emitting element, a second light emitting element, a plurality of optical microstructures and a first surface. The light guide plate has a first light incident surface and a second light incident surface. Each of the optical microstructures has a first optical surface facing the first light incident surface and a second optical surface facing the second light incident surface. A magnitude of a first included angle between the first optical surface and the first surface and a magnitude of a second included angle between the second optical surface and the first surface gradually change as getting farther away from the first surface.
