Abstract
A liquid crystal display apparatus of the invention includes: a pair of substrates and a liquid crystal layer sandwiched therebetween; a plurality of scanning signal formed on one substrate; a plurality of data signal lines arranged perpendicular to the scanning signal lines and formed on the other substrate; pixel electrodes respectively at crossing portions in which the scanning signal lines cross the data signal lines; and nonlinear resistive two-terminal devices respectively provided between the pixel electrodes and the scanning signal lines. Scanning signals each including a selection period and a non-selection period are applied to the scanning signal lines, and data signals are applied to the data signal lines. While these signals are applied to the scanning signal lines and the data signal lines, liquid crystal application signals are applied to the liquid crystal layer via the two-terminal devices. Each liquid crystal application signal has a first voltage in a writing period as a first half of the selection period and a second voltage in a regulating period as a latter half of the selection period. The first voltage is determined in accordance with video data. The second voltage is a voltage at which part of the electric charge, which is charged into the liquid crystal layer in the writing period, is released.
