STEREOSCOPIC DISPLAY DEVICE

摘要

PURPOSE: A stereoscopic display device is provided to make an electric field different according to an interval between the pupils of both eyes to vary an optical path between an image panel and a barrier, thereby preventing lowering of 3D picture quality. CONSTITUTION: An image panel(100) emits a 2D image. A barrier(300) is separated from the image panel. An optical path control panel(200) is located between the image panel and the barrier. The optical path control panel controls an optical path between the image panel and the barrier by applying a voltage.
