Abstract:
1. A liquid crystal display (LCD) device having a thin polarizing plate and a phase retardation plate, wherein a backlight unit is disposed, and a third polarizing plate entirely formed of a straight polarizing plate is disposed at a front surface of the backlight unit, wherein a second 1/2 phase retardation plate and a transparent unit are arranged at a front surface of the first transparent substrate, and a first insulation layer is disposed at the front surfaces of the second 1/2 phase retardation plate and the transparent unit, wherein a first transparent electrode and a first alignment film are sequentially disposed at a front surface of the first insulation layer, and a liquid crystal layer is disposed between the first alignment film and the second alignment film, wherein a second transparent electrode, a color filter and a second insulation layer are sequentially disposed at a front surface of the second alignment film, 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 a non-reflection coating layer is disposed at the front-most surface of the liquid crystal display (LCD) device, wherein the second 1/2 phase retardation plate and the transparent unit are formed integrally with each other on the same plane in a chessboard shape, wherein the third polarizing region and the fourth polarizing region are formed integrally with each other on the same plane in a chessboard shape, and wherein a 1/4 phase retardation plate is disposed at a front surface of the second transparent substrate so as to produce circularly-polarized light.
