Abstract
A liquid crystal display apparatus in which leakage of light caused by signal lines can be eliminated is disclosed. In the liquid crystal display apparatus, a predetermined potential corresponding to the black level is applied to the video signal lines during a period of time other than the horizontal blanking period, and image signals are transferred to one row of the pixels through the signal lines which the horizontal blanking period.
