Two-dimensional and three-dimensional image selectable display device

摘要

A display device, adapted to display a two-dimensional image or a three-dimensional image, includes an image panel for displaying an image and a barrier panel located in front of the image panel. The barrier panel includes a first substrate including In-Plane-Switching type electrodes arranged on a surface of the substrate, a second substrate having a transparent electrode on the inner side surface, and a liquid crystal layer located between the first and second substrates. The barrier panel displays the image as a two-dimensional image or a three-dimensional image depending on electric fields established between first and second substrates of the barrier panel and between the In-Plane-Switching type electrodes formed on the first substrate. The two-dimensional image may be displayed with wide viewing angle and narrow viewing angle options.
