3D IMAGE DISPLAY DEVICE

摘要

PURPOSE: A 3D image display device is provided to watch 2D video with a great luminance characteristic without the degradation of resolution by not having an area which is covered with a closing part. CONSTITUTION: A display device(115) displays a two dimensional video. A three dimensional image display device(111) includes a parallax barrier(130). The parallax barrier is piled up with the display area of a two dimension display device. The parallax barrier includes a closing part(BA) and an opening part(op). The closing part is a plurality of bar shapes. The width of the closing part is selectively varied.
