LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY DEVICE

A liquid crystal panel (2) includes: a p-type liquid crystal material sandwiched between a pair of substrates (40, 20); and pixel electrodes (13), each formed from a comb electrode, and a common electrode (14) both provided to the substrate (40). A p-type liquid crystal material is aligned in a dire...

Beschreibung
Zusammenfassung:	A liquid crystal panel (2) includes: a p-type liquid crystal material sandwiched between a pair of substrates (40, 20); and pixel electrodes (13), each formed from a comb electrode, and a common electrode (14) both provided to the substrate (40). A p-type liquid crystal material is aligned in a direction perpendicular to substrate surfaces while no electric field is applied. The comb electrodes each have an electrode width of not more than 5 µm and an electrode spacing of not more than 15 µm. The pixel electrode (13) and the common electrode (14) serve to apply to the p-type liquid crystal material an electric field parallel to the substrate surface. A voltage of not less than 7 V is applied between the pixel electrode (13) and the common electrode (14) when the liquid crystal panel is driven. The p-type liquid crystal material has, in a range from 0.9 to 2.5, a product of a dielectric anisotropy µ and a refractive index anisotropy n.
