The light guide plate includes a light-transmissive substrate and optical structures. The light-transmissive substrate has a first surface, an opposite second surface, and an incident surface connecting the first and the second surface. The light beam enters the light-transmissive substrate through the incident surface and is emitted out of the light-transmissive substrate through the first surface. The optical structures are disposed on the second surface. Each optical structure has a first total internal reflection (TIR) surface, a second TIR surface, and a third TIR surface. The second TIR surface connects the first and third TIR surfaces. Part of the light beam from the incident surface is totally internally reflected by any adjacent two of the first, second, and third TIR surfaces in sequence.
