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.

摘要： A method of producing a polarizing plate of the present invention comprises the steps of: bonding a protective film to at least one side of a polarizing film that is produced through at least uniaxial stretching and has an absorption axis in the uniaxial stretching direction, and removing by cutting at least one of the edges of the polarizing film that are substantially parallel to the direction of the absorption axis before the bonding the protective film. The method widen the effective width of the polarizing plate, and a large size polarizing plate was obtained.

摘要： It is an object of the present invention to provide a liquid crystal display panel having a high contrast ratio in a front direction.A liquid crystal panel according to an embodiment of the present invention includes: a liquid crystal cell; a first polarizing plate placed on one side of the liquid crystal cell; a second polarizing plate placed on the other side of the liquid crystal cell; and a retardation layer placed between the liquid crystal cell and the second polarizing plate. A refractive index ellipsoid of the retardation layer exhibits a relationship of n≧ny>nz; and 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 higher contrast ratio in a front direction than that of a conventional liquid crystal panel (for example, a liquid crystal panel in which the light transmittances of two polarizing plates placed on both sides of a liquid crystal cell are the same), and shows excellent display properties.
