摘要： The objective is to provide a stereoscopic display device that can be switched among 2D display mode, 3D display mode and mirror mode, where 2D display may be realized even while the device is staying in 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 is located closer to the viewer than the display panel is. The absorptive polarizer is located closer to the viewer than the switch liquid crystal panel is. The reflective polarizer is located between the display panel and the switch liquid crystal panel. The reflective polarizer passes those components of light entering the reflective polarizer that are parallel to the transmission axis (L6) while reflecting those components that are perpendicular to the transmission axis. At least one of the substrates (32, 34) includes a transparent region (58) capable of passing light from the display panel.
