Abstract:
A picture electrode of an MVA liquid crystal display device has a configuration where sub-picture electrodes are successively provided, while a cross-shaped slit is provided as an alignment restriction member on a common electrode of the side of a counter substrate. A columnar spacer is provided on a signal line of a TFT substrate in conformity to a position of a singular point of an alignment of liquid crystal molecules, the singularity occurring in a display region. This structure makes it possible, when a panel surface is depressed, to cause quick re-aligning of the liquid crystal molecules at the singular point of +1, as a base point, which has occurred at a center of the cross-shaped slit and in the vicinity of the columnar spacer, hence achieving a speedy recovery of displaying.
