OPTICAL SHEET FOR THREE-DIMENSIONAL AND TWO-DIMENSIONAL IMAGE AND IMAGE DISPLAY DEVICE USING THE SAME

摘要

An optical sheet for 2D and 3D image using a switching lens and a second lens, and image display device using thereof is provided to perform 2D and 3D without a degradation of a picture quality by controlling a progressive direction of an image light which is income in a display panel. An optical sheet for 2D and 3D image using a switching lens and a second lens comprises the followings: a first light converting unit changing a progressive direction of a light according to an applied electric field; a first and second transparent electrodes applying the electric field to the first light converting unit, and located in the first light converting unit; and a second light converting unit changing a progressive direction of a light, and formed on the first light converting unit. The first light converting unit is made of a liquid crystal.
