Patent ID: 7898638

Claim:
A liquid-crystal display device comprising: a liquid-crystal panel including a pair of substrates, a liquid-crystal layer held in sandwiched form between the pair of substrates, and a common electrode, a signal electrode and a scan electrode formed on at least a counterpart of the pair of substrates for applying an electric field to the liquid-crystal layer; a pair of polarizers disposed on a pair of substrates; and a light source unit disposed outside the pair of substrates, wherein the liquid-crystal layer includes a liquid-crystal material having an ordinary-light refractive index of at least 1.46, but up to 1.49, an extraordinary-light refractive index of at least 1.54, but up to 1.59, and a mean photoelastic constant of at least 8×10 −12 N, but up to 25×10− 12 N, and exhibiting a nematic phase, where the liquid crystal of the liquid crystal layer is aligned in a direction of the scan electrode.
