A novel method for switching the viewing-angle of a liquid crystal display is proposed by using a polymernetworked liquid crystal cell in combination with a collimated backlight system. The bright state for a wide viewing-angle is obtained aligning liquid crystals randomly in polymer-networked structure, which diffuses a collimated backlight. The liquid crystals homogeneous-aligned by in-plane switching are operated as the bright state for a narrow viewing-angle since a collimated backlight passes through the liquid crystal layer intactly. It is demonstrated experimentally that the viewing-angle can be controlled omni-directionally without an additional panel or an additional backlight system.
