Abstract
This document discloses a stereoscopic image display device. In the image display device, a display device displays a first image data and a second image data in a time-dividing manner. A switchable retarder panel is configured to control light emitted from the display device and is made of electrically controlled birefringence (ECB) liquid crystals. Polarization glasses polarize the light emitted from the switchable retarder panel. The polarization glasses comprise a left eyeglass comprising a polarizer having a tilt of 45° about a light absorbing axis, and a right eyeglass comprising a polarizer having a tilt of 135° about the light absorbing axis.
