ABSTRACT:
The invention provides a liquid crystal display device in which generation of display defects, such as afterimages or spot-shaped stains, can be reduced or suppressed, and in addition a bright display having a wide viewing angle can be obtained, in a transflective liquid crystal display device. A liquid crystal display device according to the present invention includes a liquid crystal layer interposed between a pair of substrates, and a transmissive display area and a reflective display area provided in one dot area. The liquid crystal layer includes a liquid crystal having a negative dielectric anisotropy representing that an initial alignment state is a vertical alignment, and pixel electrodes to drive the liquid crystal and a common electrode are formed in the liquid crystal layer sides of the pair of substrates, respectively. In the pixel electrodes, as an alignment regulating device to regulate alignment of the liquid crystal, slits formed by opening some parts of the electrodes are formed in the transmissive display areas, and the slits are arranged to two-dimensionally overlap with a reflective film.
