Abstract:
A liquid crystal panel of the present invention comprise a liquid crystal cell, a first polarizer arranged on one of both sides of the liquid crystal cell, and a second polarizer arranged on the other side of the liquid crystal cell, wherein at least one of the first and the second polarizers is dyed with a dichroic material, and the dichroic ratio thereof is from 40 to 100. At least one of the polarizers preferably has a polarization degree of 99% or more and a single transmittance of 35% to 45%. Further, at least one of the polarizers preferably exhibits the following birefringence: Δnxy is from 0.015 to 0.030.The liquid crystal panel of the present invention has the above polarizers, therefore the liquid crystal panel attains high contrast ratio in oblique directions and excellent display characteristics.
