Patent ID: 8184216

Claim:
A liquid crystal display (LCD) device having a thin polarizing plate and a phase retardation plate, wherein a first transparent substrate is disposed at a front surface of a backlight unit, wherein a first polarizing region having a polarizing direction of 0° and 45° and a second polarizing region having a polarizing direction of 90° or 135° are formed on a front surface of the first transparent substrate in such a manner as to be alternately arranged with each other on the same plane, wherein a first insulation layer is stacked on the front surfaces of the first polarizing region and the second polarizing region, wherein a liquid crystal layer is disposed between a first alignment film and a second alignment film, wherein a first transparent electrode and the first alignment film are disposed at a front surface of the first insulating layer, wherein a second transparent electrode and a color filter are disposed at a front surface of the second alignment film, and a second insulation layer is formed at a front surface of the color filter, wherein a third polarizing region, a fourth polarizing region and a second transparent substrate are sequentially disposed at a front surface of the second insulation layer, and wherein a non-reflection coating layer is disposed at the front-most surface of the liquid crystal display (LCD) device, wherein the first polarizing region and the second polarizing region are integrally formed with each other in a chessboard shape, wherein the third polarizing region and the fourth polarizing region are integrally formed at the front surface of the second insulating layer in such a manner as to be arranged on the same plane in a chessboard shape in a structure in which the polarizing directions thereof are orthogonal to those of the first polarizing region and the second polarizing region, respectively, wherein a ¼ phase retardation plate is disposed at a front surface of the second transparent substrate, and that the polarizing plates of the first polarizing region, the second polarizing region, the third polarizing region and the fourth polarizing region employ conductive polarizing plates, respectively.
