Abstract

PURPOSE: A liquid crystal display of high contrast and high-speed response that is made by placing a specific nematic liquid crystal between the semi-conductor base plate which is provided with an active element for driving liquid crylstal in a matrix and the glass base plate which is provided with a transparent electrode, thus displaying images by appliying or removing a voltage.
CONSTITUTION: The objective crystal display is made by placing a nematic liquid crystal of positive dielectric anisotropy of formulaI(R1 is straight-chain alkyl), which contains a dichromic dye showing different colors according to the direction of molecular orientation, between the one base plate that is prepared by providing an active element for driving the liquid crystal on a semiconductor base plate in a matrix and forming a whitened matal layer on the display electrode attached to the active element and the other glass base plate provided with the transparent electrode opposing to the former base plate so that the liquid crystal is oriented homogeneously and the image is displayed by applying and removing a voltage. The above liquid crystal composition preferably contains compounds of formula II (R2, R3 are straight-chainalkyl), formula III (R4 is straight-chain alkyl) and formula IV (R5 is straight-chain alkyl).
