Abstract
The objective is to provide a stereoscopic display device that can be switched among 2D display mode, 3D display mode and mirror mode. The device includes: a display panel (12); a switch liquid crystal panel (14); an absorptive polarizer (16); and a reflective polarizer (22). The switch liquid crystal panel (14) is located closer to the viewer than the display panel (12) is. The absorptive polarizer (16) is located closer to the viewer than the switch liquid crystal panel (14) is. The reflective polarizer (22) is located between the display panel (12) and the switch liquid crystal panel (14). The reflective polarizer (22) has a transmission axis (L6) perpendicular to the transmission axis (L3) of the absorptive polarizer (16) and passes those components of light entering the reflective polarizer (22) that are parallel to the transmission axis (L6) while reflecting those components that are perpendicular to the transmission axis (L6).
