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