DISPLAY APPARATUS FOR DISPLAYING THREE DIMENSIONAL PICTURE

摘要

PURPOSE: A stereoscopic image display device is provided to emit collimated light using an image panel illumination holographic optical element while maintaining the shape of an existing normal display device and thin vertical thickness. CONSTITUTION: A stereoscopic image display device includes an image panel(100), an image panel lamp holographic optical element(200), a light source(500), an image panel memory holographic optical element(300) and a flat mirror(600). The image panel outputs an image. The image panel lamp holographic optical element supplies backlight on the front surface of the image panel. The light source generates collimated light. The image panel memory holographic optical element reflects the light outputted from the light source while memorizing the shape of the image panel lamp holographic optical element. The flat mirror composed of a mirror having a flat shape reflects the light reflected from the image panel memory holographic optical element using the image panel lamp holographic optical element.
