Abstract

A stereoscopic image display device that enables 2D / 3D image output conversion includes a display panel configured to display an image and a polarization lens panel disposed on the display panel and configured to transmit as-is or refract light supplied from the display panel according to an image display mode. The polarization lens panel includes: first and second substrates; a lower electrode formed on the first substrate; an upper electrode formed on the second substrate; and a polymer liquid crystal layer formed of a polymer liquid crystal in which a polymer and a liquid crystal are combined, and disposed between the lower electrode and the upper electrode.

Description

[0001] This application claims the benefit of Korean Patent Application Nos. 10-2012-0139914 and 10-2012-0139912 filed on December 4, 2012, which are hereby incorporated by reference as if fully set forth herein. technical field [0002] The present invention relates to a stereoscopic image display device, in particular to a stereoscopic image display device which allows a viewer to watch a stereoscopic image without glasses. Background technique [0003] A stereoscopic (three-dimensional (3D)) image display device is a device that provides different images to left and right eyes of a viewer, thereby enabling the viewer to view stereoscopic images due to binocular parallax between the left and right eyes. [0004] Recently, active research is being conducted on a glasses-free technology in which a user does not wear stereoscopic glasses. Examples of the glasses-free technique include a lens technique that separates left and right images by using a lenticular lens array and a...
