To provide a large screen display device constituted so that transmitted light quantity is large and the frequency of a dot voltage impressing signal is reduced.

In this device; a liquid crystal cell is divided to plural square pixels, the pixels are nearly trisected to three juxtaposed 1st rectangles, and the dot of the liquid crystal cell is formed so that the trisected parts may be the respective dots 1 of R, G and B. A color display surface part 4 is divided to plural square pixels, the pixels are trisected to three laterally juxtaposed 2nd rectangles, and the dot of the color display surface part is formed so that the trisected parts may be the respective dots of R, G and B. One dot of the liquid crystal cell and one dot of the color display surface part corresponding thereto are coupled through three juxtaposed optical fibers.
