Abstract

PURPOSE: A liquid crystal display capable of being highly densified and usable for a variety of cheap and readily recognizable meter displays, etc., in addition to the display of a portable instrument, which is prepd. by enclosing a liquid crystal mixt. contg. at least two compounds of a specified formula in a cell of specified thickness.
CONSTITUTION: A liquid crystal mixt. contg. at least two compounds of formulaI (wherein X is a group of formula II or III, where n is 1W7; Y is a group of formula IV or -CN) such as a compd. of formula V or VI, is enclosed in a cell having a crystal layer 3W6μ in thickness to form a twisted nematic liquid crystal display drived by an electric field. Even in a display employing voltage averaging method, high density of at least 1/32 duty, i.e., twice the conventional density, is achieved with the same or better display quality than that corresponding to 1/16W1/18 duty. Thus the liquid crystal display is widely used as a display for a cheap and readily recognizable desktop computer terminal and a variety of meters in addition to a flatpanel display used for a cordless microcomputer and a variety of portable instruments, for which it has been believed impossible to use the liquid crystal display.
