Abstract
PURPOSE: To provide the title device showing slight temp. dependence of threshold voltage, requiring no yellow filter, and using a mixed liquid crystal of two or more kinds of biphenylnitrile derivatives, two or more kinds of benzoyloxybenzene derivatives and one or two kinds of benzoyloxy P-benzoyloxybenzene derivatives.
CONSTITUTION: In a liquid crystal display device housing polarizing plates and an oriented nematic liquid crystal mixt. with positive dielectric anisotropy sealed in between a pair of electrode plates, the mixt. is selected as follows; the first component is two or more kinds of biphenyl type liquid crystals of formula I, the second component two or more kinds of ester type liquid crystals of formula II and the third component one or two kinds of ester type liquid crystals of formula III. In the formulae, R1; n-C5H11, n-C6H13 or n-C7H15, R2; CH3 or n-C6H13 R3; n-C5H11 or n-C7H15 and R4; C2H5 or n-C4H9.
