Abstract
The present invention discloses a parallax-barrier comprising a Liquid-Crystal layer (LC layer) including pixels arranged in cell type matrix structure to form a barrier of horizontal or vertical direction according to a predetermined control method, a controller for controlling said pixels of said LC layer in order to form a barrier pattern of horizontal or vertical direction pattern, by turning said pixels on or off selectively according to said control method, a lower layer formed between said LC layer and a predetermined display module in order to dispose said LC layer and said controller at a position off from said display module by a predetermined distance, an upper layer formed on the top of said LC layer in order to dispose said LC layer and said controller, and a polarizer formed on the top of said upper layer, and visualizing said barrier according to said barrier pattern which is formed on said LC layer by controlling polarization angle of the light, wherein said light being emitted from said display module and passing through said lower layer, said LC layer and said upper layer. Thus, stereoscopic images that are rotated in the horizontal/vertical direction can be displ…
