Abstract
A 2D/3D image switching type liquid crystal display is described. The 2D/3D image switching type liquid crystal display includes a liquid crystal display (LCD), a film-type patterned retarder (FPR) and a liquid crystal barrier layer. When either the FPR is disposed between the LCD panel and the liquid crystal barrier layer or liquid crystal barrier layer is disposed between the LCD panel and the backlight module, an electrical field controls the first grating regions and the second grating regions to form a bright region and a dark region for adjusting the left-hand circularly polarized light and the right-hand circularly polarized light from the FPR to switch 2D/3D image by switching the liquid crystal barrier layer.
