Provided is a liquid crystal device having a high contrast ratio in a forward direction. The liquid crystal device comprises a liquid crystal cell, a first polarizing plate arranged on one side of the liquid crystal cell, a second polarizing plate arranged on the other side of the liquid crystal cell, and a phase difference layer arranged between the liquid crystal cell and the second polarizing plate. The liquid crystal device uses a liquid crystal panel, in which a refractive index oval element of the phase difference layer indicates relations of nx >= ny > nz and in which the second polarizing plate has a transmittivity (T2) larger than the transmittivity (T1) of the first polarizing plate. This liquid crystal panel exhibits such display characteristics as have a drastically higher and more excellent contrast ratio in the forward direction than that of the liquid crystal panel of the prior art, in which two polarizing plates arranged on the two sides of the liquid crystal cell have equal transmittivities.
