An LCD module includes an LCD panel, and a polarizing plate formed on each of the upper and lower surfaces of the LCD panel. The polarizing plate includes a polarizer and a polyester film formed on at least one surface of the polarizer. The polyester film has a difference between the index of refraction in the x-axis direction and the index of refraction in the z-axis direction (nx&#x2212;nz) of about 0.1 to about 0.18, where nx and nz are the indices of refraction in the x-axis and z-axis directions, respectively, at a wavelength of 550 nm. The LCD module has a CR 45&#xb0; and a CR 135&#xb0; of about 1.0% or greater.

Module for liquid crystal display apparatus and liquid crystal display apparatus comprising the same

A polarizing plate, a method of preparing the same and a liquid crystal display apparatus including the same are disclosed. The polarizing plate includes a polarizer and a polyester film formed on a surface of the polarizer, wherein the polyester film has a ratio of an elongation ratio in a machine direction to an elongation ratio in a transverse direction of about 1:0.8 to about 1:1.2, an in-plane retardation (Re) of about 500 nm or less at a wavelength of 550 nm, and an out-of-plane retardation (Rth) of about 10,000 nm or less at a wavelength of 550 nm.

Polarizing plate, method of preparing the same, and liquid crystal display apparatus including the same

A polarizing plate includes a polarizer, a retardation film on a first side (e.g., a lower side) of the polarizer, and a protective film on a second side (e.g., an upper side) of the polarizer. The retardation film has an axis distortion angle between a fast axis of the retardation film and an absorption axis of the polarizer of about +0.03&#xb0; to less than +0.2&#xb0;. The protective film has an in-plane phase difference (Ro) of greater than about 10,000 nm and about 15,000 nm or less at a wavelength of 550 nm. A liquid crystal display apparatus includes the polarizing plate.

Polarizing plate and liquid crystal display apparatus including the same

A polarizing plate includes a polarizer; and a protective film attached to at least one side of the polarizer via an adhesive layer. The adhesive layer is formed of a water-based adhesive including a polyvinyl alcohol resin, a zirconium compound, and an imine crosslinking agent. The polarizing plate has a variation in light transmittance (|B&#x2212;A|) from 0% to about 0.25% at wavelengths from 400 nm to 780 nm, where A is an average value of initial light transmittance of the polarizing plate at wavelengths from 400 nm to 780 nm, and B is an average value of light transmittance of the polarizing plate at wavelengths from 400 nm to 780 nm measured after the polarizing plate has been dipped in water of 25&#xb0; C. for 3 hours, followed by drying at 25&#xb0; C. for 2 hours.

Polarizing plate and liquid crystal display including the same

A liquid crystal display includes a liquid crystal panel, a first polarizer plate stacked on an upper surface of the liquid crystal panel, and a second polarizer plate stacked on a lower surface of the liquid crystal panel. The first polarizer plate may have an absorption axis inclination of +0.1 to +0.2 degrees, or the second polarizer plate may have an absorption axis inclination of &#x2212;0.04 to less than 0 or greater than 0 to +0.1 degrees.
