BACKLIGHT UNIT FOR AUTOSTEREOSCOPIC 3-DIMENSION IMAGE DISPLAY DEVICE

摘要

PURPOSE: A backlight for an autostereoscopic three-dimensional display device is provided to achieve a simple manufacturing method and a large area by aligning a lenticular film and a barrier film simply. CONSTITUTION: A light guide panel(30) has a first plane and a second plane facing the first plane, and changes the path of light from a light source to the side of the first plane. A first prism film(20) is stacked on the first plane of the light guide panel. A second prism film(10) is stacked on the top of the first prism film and forms a variable prism pattern on a light emission plane. The variable prism pattern has a plurality of unit prisms arranged in a line. A first unit prism has different left and right bottom angles from an adjacent second unit prism.
