Abstract
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−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° and a CR 135° of about 1.0% or greater.
