Abstract
PURPOSE: To obtain the color liquid crystal display device which is capable of performing diversified displaying of bright background and good contrast by laminating a plurality of the guest-host liquid crystal display cells which perform displaying of different colors through homeotropic orientation.
CONSTITUTION: The liquid crystal layer composed of N-type nematic liquid crystal 15 and dye molecules 17a of A color is sandwiched between an intermediate substrate 11 provided with the display electrodes 12a, 12b of the same shape on the top and bottom surfaces and an upper substrate 11a provided with display electrodes 13a. The liquid crystal layer composed of liquid crysal 15 and dye molecules 17 of B color is sandwiched between substrate 11 and the lower substrate 11b provided with display electrode 13b, and the above-mentioned liquid crystal layers are homeotropically oriented to form the display device. With the above-mentioned display device, the display of the portions (background portions) where there is no voltage application becomes nearly of a white color and with this as a background, the distinct displaying of A color and B color and mixed colors of A and B, respectively, may be perfomed by applying voltage to the upper liquid crystal layer, lower liquid crystal layer or both upper and lower liquid crystal layers.
