Surface light source and liquid crystal display device using the same
A surface light source includes a prism sheet placed on one side of a liquid crystal display panel, and having elongated prism portions formed to form a patterned indented entrance surface having an angular cross-section, and an exit surface. A reflecting plate is placed to face the prism sheet through a space. First and second light source units are disposed on two end sides. A control unit sequentially writes left-eye image data and right-eye image data on respective pixels of the display panel, causes the light source unit on the right side when viewed from an observation side of the surface light source to emit light in synchronism with the writing of the left-eye image data, and causes the light source unit on the left side to emit light in synchronism with the writing of the right-eye image data.
