ABSTRACT:
Disclosed is an ultra slimmed LCD capable of being applied to a hand-held terminal such as a cellular phone. In the LCD, a first substrate includes a pixel electrode. A switching element is formed on an inner surface of the first substrate, and turns on or off the pixel electrode. A first polarizing plate is attached on an outer surface of the first substrate. A second substrate faces the first substrate, and includes a color filter layer for displaying a color image. A common electrode is formed on the color filter layer. The second substrate converts a linear light input through one side face of the second substrate into a planar light. A liquid crystal layer is interposed between the first substrate and the second substrate. A second polarizing plate is arranged between the liquid crystal layer and the second substrate, and converts the planar light converted through the second substrate into a light vibrating in a predetermined direction. The second polarizing plate includes a polyvinyl alcohol layer of polymer polarization medium arranged at a middle layer, and two supporter layers of triacetyl cellulose arranged at upper and lower outer faces of the polyvinyl alcohol layer, respectively.
