摘要:
It is an object of the present invention to provide a liquid crystal display panel having a high contrast ratio. A liquid crystal panel according to an embodiment of the present invention includes: a liquid crystal cell; a first polarizing plate placed on a viewer side of the liquid crystal cell; and a second polarizing plate placed on an opposite side of the liquid crystal cell with respect to the viewer side. A light transmittance (T2) of the second polarizing plate is larger than a light transmittance (T1) of the first polarizing plate. Such a liquid crystal panel has a remarkably high contrast ratio and shows excellent display properties, compared to conventional liquid crystal panel.
