Abstract
A liquid crystal display device includes two substrates, liquid crystal therebetween, and sub-pixel regions. Each sub-pixel region is divided into first to fourth display regions by a first axis extending orthogonal to an optical axis of a polarizing plate and a second axis extending orthogonal to the first axis. Each first to fourth display region includes slit electrodes on the second electrodes along the first axis. First slit electrodes in the first display region and second slit electrodes in the second display region are symmetric relative to the first axis. Third slit electrodes in the third display region and fourth slit electrodes in the fourth display region are symmetric relative to the first axis. The first and fourth slit electrodes are symmetric relative to the second axis. The second and third slit electrodes are symmetric relative to the second axis.
