Abstract
A liquid crystal display device comprises a liquid crystal panel including sub-pixels and a back light for irradiating light to the back surface of liquid crystal panel. A transmission sub-pixel can be switched into an image display state which can allow irradiated light to exit, and a black display state which does not allow irradiated light to exit. A mirror sub-pixel can be switched between a mirror state which can allow reflected light to exit and a non-mirror state which does not allow reflected light to exit, independently of the transmission sub-pixel. A control unit places each transmission sub-pixel into the image display state or black display state, and places each mirror sub-pixel into the mirror state or non-mirror state.
