Abstract
A 2D/3D switching type liquid crystal display device includes: (i) display liquid crystal panel () for generating an image in accordance with input image data; (ii) patterned retardation plate () for rendering a certain viewing angle to a display image during 3D display, so as to provide a 3D effect; and (iii) a switching liquid crystal panel () for switching 2D display and 3D display by activating and deactivating the effect of the parallax barrier means. The patterned retardation plate () and the switching liquid crystal panel () respectively have wider active areas than an active area of the display image generating means. With this, the 2D/3D switching liquid crystal display device allows for a viewing angle in 2D as wide as a viewing angle of 2D-only display.
