Abstract:
1. A liquid crystal display (LCD) panel comprising: a first substrate and a second substrate, including a plurality of sub pixels, bonded to each other; a liquid crystal layer interposed between the first and second substrates; a common electrode and a pixel electrode formed on an inner surface of the first substrate and the second substrate respectively to drive the liquid crystal layer; a plurality of first polarization wire grids formed in a single direction on an entire front surface of the first substrate, opposite to the inner surface including the common electrode; and a plurality of second polarization wire grids formed in a single direction on an entire rear surface of the second substrate, opposite to the inner surface including the pixel electrode, wherein each of the plurality of first polarization wire grids has a thickness of several hundred-thousand Å, and a width of several μm, wherein each of the plurality of second polarization wire grids has a thickness of several hundred-thousand Å, and a width of several μm, wherein the plurality of first polarization wire grids and the plurality of second polarization wire grids are made of a metal material, which includes one of copper and aluminum, wherein the plurality of first polarization wire grids are arranged in parallel at regular intervals of several μm on a front surface of the first substrate, and the plurality of second polarization wire grids are arranged in parallel at regular intervals of several μm on a rear surface of the second substrate, wherein a color filter layer is formed on the inner of the surface of the first substrate to overlap with the plurality of the first polarization wire grids in one-to-many correspondence; wherein the first polarization wire grids are formed on the front surface of the first substrate including the color filter layer; and wherein the pixel electrode having smaller area than the common electrode overlaps with the plurality of first polarization wire grids in one-to-many correspondence.
