Abstract
In a stereoscopic image conversion panel for enhancing display quality and a stereoscopic image display apparatus having the panel, the stereoscopic display panel includes lower and upper transparent substrates, lower and upper transparent electrodes, and a liquid crystal lens layer. The lower and upper transparent substrates face each other. The lower transparent electrodes are disposed on the lower transparent substrate, formed along a first direction, and formed substantially in parallel with each other along a second direction. The upper transparent electrodes are disposed on the upper transparent substrate, formed along the second direction, and formed substantially in parallel with each other along the first direction. The liquid crystal lens layer is disposed between the upper and lower transparent substrates, and a longitudinal arrangement direction of liquid crystal molecules of the liquid crystal lens layer is changed by an electric field to have a predetermined refractive index. Therefore, a refracted incident light produces a stereoscopic image for enhancing display quality.
