Abstract
A reflective type fringe field switching mode liquid crystal display device having improved contrast is provided. The device has a lower and an upper substrates arranged with a distance and having a unit pixel defined therein. Between the substrates, a liquid crystal layer having a plurality of liquid crystal molecules are interposed. A counter electrode is formed on an inner surface of the lower substrate in the unit pixel. A pixel electrode is formed above the counter electrode. The pixel electrode and the counter electrode generate a fringe field for driving the liquid crystal molecules in the unit pixel. A horizontal alignment layer having a rubbing axis is interposed between the lower substrate and the liquid crystal layer, and a vertical alignment layer is interposed between the upper substrate and the liquid crystal layer. In addition, a polarizer is disposed on an outer surface of the upper substrate and having a polarizing axis.
