Abstract
Provide is a stereoscopic display device that is capable of, while preventing the crosstalk ratio from deteriorating, increasing the brightness during 3D display, switching 2D display and 3D display without decreases in the resolution, and achieving a switching response speed at the same level as that in the parallax barrier method. A switching liquid crystal panel (14) includes: a pair of substrates (28, 30); a liquid crystal layer (32) sealed between the substrates in pair (28, 30); a common electrode (38) formed over an entirety of an area where a parallax barrier (48) is realized on the substrate (30); and a plurality of drive electrodes (34) formed on the substrate (28), the drive electrodes (34), in collaboration with the common electrode (38), forming light-shielding parts (44) when a voltage is applied thereto, wherein the transmission parts (46) has an opening width that is equal to or greater than an opening width of the pixels (26) in a direction in which the transmission parts (46) and the light-shielding parts (44) are arrayed alternately.
