Abstract
A liquid crystal display module includes first and second polarizing plates, and a liquid crystal panel between the polarizing plates. The second polarizing plate comprises an optical film on a polarizer. The optical film comprises a high refractive index pattern layer having at least one engraved pattern, and a low refractive index pattern layer having a filling pattern that fills at least a portion of the engraved pattern. The high refractive index pattern layer has a higher refractive index than the low refractive index pattern layer. The optical film is disposed such that light emitted from the liquid crystal panel will enter the low refractive index pattern layer and then be emitted through the high refractive index pattern layer. A liquid crystal display includes the liquid crystal display module.
