Abstract: Disclosed is a stereoscopic display device that can reduce moiré that occurs due to light-shielding areas in the aperture of pixels. The stereoscopic display device includes a display panel and a parallax barrier. The display panel has a plurality of pixels and displays a stereoscopic image. In the parallax barrier, the direction in which transmissive and non-transmissive parts are alternately arranged is the first direction and the lengthwise direction of the non-transmissive parts is the second direction. There is a boundary that extends in the second direction between two pixels next to each other in the first direction. There are light-shielding areas in the aperture of each pixel. There is a space between the boundary and the light-shielding areas. Of two pixels next to each other in the second direction, the light-shielding areas in the aperture of one pixel are shifted in the first direction with respect to the light-shielding areas in the aperture of the other pixel.

The device includes: a display panel (12); a switch liquid crystal panel (14); an absorptive polarizer (16); and a reflective polarizer (22).

Abstract: 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.

At least one of the substrates (32, 34) includes a transparent region (58) capable of passing light from the display panel.

A parallax barrier (42) includes transparent portions (48) and light-shielding portions (46) arranged alternatingly. Supposing that a first direction is a direction in which the light-shielding portions (46) and the transparent portions (48) are arranged alternatingly and a second direction is a longitudinal direction of the light-shielding portions (46), a boundary portion (52) is present between two adjacent pixels (50) arranged in the first direction and extends in the second direction, and the edges (381, 382) of the light-shielding portions (46) disposed in the first direction have portions crossing a reference line (L) extending in the second direction and fluctuate in a specified cycle along the second direction.

A switching liquid crystal panel (14) provided in the stereoscopic display device of the present invention realizes a parallax barrier (48) in which transmission parts (52) and light shielding parts (50) are arrayed alternately. The switching liquid crystal panel (14) includes a pair of substrates (30, 32) on which drive electrodes (36, 42) and auxiliary electrodes (38, 44) are arranged alternately.

Abstract: A display device 10 includes a liquid crystal panel 11 and a parallax barrier 12. The liquid crystal panel 11 includes pixels PX linearly arranged in at least one direction and light blocking sections 11f each arranged between adjacent pixels PX. The parallax barrier 12 faces the liquid crystal panel 11 and is configured to separate an image displayed on the pixels PX by parallax. The parallax barrier 12 includes barrier sections BA and barrier openings BO. The barrier sections BA are arranged in the arrangement direction of the pixels and configured to block light. The barrier openings BO are each arranged between adjacent barrier sections BA and allow the light to pass therethrough. Each barrier section BA has a dimension measured in the arrangement direction that satisfies Expression (1), in which Wb (?m) is the dimension of each barrier section, A (?m) is a dimension of each pixel, and B (?m) is a dimension of each light blocking section measured in the arrangement direction.
