ABSTRACT:
The present invention discloses a reflective type ferroelectric liquid crystal display and a driving method thereof. The reflective type ferroelectric liquid crystal display comprises a display panel which is disposed between a polarization beam splitter and a mirror to satisfy a quarter plate condition, and in which a liquid crystal layer formed between electrode layers is filled with half-V type ferroelectric liquid crystal having a bookshelf structure, the electrode layers being disposed between substrates to be orthogonal and opposite to each other; and a compensation panel which is disposed between the display panel and the polarization beam splitter to satisfy a half plate condition, and in which a liquid crystal layer formed between electrode layers is filled with half-V type ferroelectric liquid crystal having a bookshelf structure, the electrode layers being disposed between substrates to be opposite to each other. Therefore, the light loss can be reduced, and thus the gray scale display can be improved.
