<P>PROBLEM TO BE SOLVED: To solve the problem, wherein when a light is converted into polarized light by being transmitted through a polarizing plate of a pair of liquid crystal shutter spectacles by using a non-polarized display, transmittance becomes low and an image gets remarkably dark, when performing stereoscopic vision; and when a shutter mechanism is arranged in front of the display, a switch mechanism becomes large and manufacturing cost becomes high, and wasteful power consumption arises because light emission in a period in which the shutter spectacles are not open is not visually confirmed as the stereoscopic vision. <P>SOLUTION: Right and left images of circularly polarized light from a display part are observed, by using a circularly polarized light filter spectacles having constitution by using a quarter-wave plate and a liquid crystal cell, or using circularly polarized light filter spectacles having constitution using a quarter-wave plate, capable of switching an optical axis and a polarizing plate as the shutter spectacles for stereoscopic vision for observing the right and left images by alternately displaying the right and left images by arranging the quarter-wave plate on a surface of a liquid crystal display from which the polarized light is emitted. Light emission by a backlight of the liquid crystal display is restricted, only during the period in which it is visually confirmed as the stereoscopic vision. <P>COPYRIGHT: (C)2011,JPO&INPIT |
