International ClassH04N 009/47Foreign Application Priority Data1997-08-29 JPAbstractIn a 3-D image display device, a parallax barrier having a plurality of apertures is provided in front of an LCD element. Each aperture is equipped with a color filter of any one of red, green, and blue colors. The LCD element conducts monochromatic display, and hence, no color filters are provided therein. In the LCD element, regarding each color, a pixel group is provided at each position corresponding to the color filter of the color, the pixel group being composed of a plurality of pixels which are driven in response to an image signal corresponding to the color. With this arrangement, when the number of parallax images for a 3-D image is increased so that a fine 3-D image is obtained, the yield of the display element, and further, the yield of the 3-D image display device, can be improved. Besides, the cost of the device can be lowered.Field of SearchSTEREOSCOPICStereoscopic display device Single display with optical path division Separation by time division Separation by lenticular screen SPECIAL APPLICATIONS Head-up display OBJECT TRACKING More than two display devices With observer selected field of view HOLOGRAPHIC IMAGE SUPERPOSITION BY OPTICAL MEANS (E.G., HEADS-UP DISPLAY) Plural image superposition DATA RESPONSIVE CRT DISPLAY CONTROL Three-dimensional arrays Stereoscopic imaging or three dimensional imaging STEREOSCOPIC Having record with lenticular surface | |
