Patent ID: 8178173

Claim:
A liquid crystal display panel, comprising: first and second substrates facing each other; a liquid crystal medium with positive dielectric anisotropy, held by the first and second substrates therebetween; and comb-like first and second electrodes disposed in parallel to each other on the first substrate, the liquid crystal medium comprising liquid crystal compounds that align vertically to the first and second substrate surfaces in the absence of applied voltage, wherein the liquid crystal mediums consists essentially of, in 100% by weight of all the liquid crystal compounds, 15 to 20% by weight of a compound of formula I, 22 to 27% by weight of a compound of formula II, 1 to 5% by weight of a compound of formula III, 4 to 8% by weight of a compound of formula IV, 15 to 20% by weight of a compound of formula V, 5 to 10% by weight of a compound of formula VI, 7 to 10% by weight of a compound of the formula VII 1 to 5% by weight of a compound of formula VIII, and 15 to 20% by weight of a compound of formula IX, in the formulae, R 1 , R 3 , R 3 *, R 5 , R 6 , R 7 , R 8 , and R 9 independently denoting C 2-5 linear alkyl, R 2 denoting C 4-6 linear alkyl, R 4 denoting C 1-3 linear alkyl.
