Abstract:
There is provided a liquid crystal display panel having a high contrast ratio in a front direction. A liquid crystal panel of the present invention includes: a liquid crystal cell; a first polarizing plate placed on one side of the liquid crystal cell; and a second polarizing plate placed on another side of the liquid crystal cell. A transmittance (T1) of the first polarizing plate is higher than a transmittance (T2) of the second polarizing plate. Preferably, a difference (ΔT=T1−T2) between the transmittance (T1) of the first polarizing plate and the transmittance (T2) of the second polarizing plate is 0.1% to 6.0%.
