To restrain cross-talk caused by floating capacitance of switching elements contained in an active matrix liquid crystal display apparatus, the active matrix liquid crystal display apparatus includes a matrix structure in which there are scanning lines and signal lines which intersect with each other in the form of a matrix and liquid crystal pixels and switching elements are arranged at the intersections. The signal lines are comprised of transparent electrodes formed in liquid crystal cells, and the scanning lines are comprised of discharge channels formed in plasma cells. The discharge channels are formed by cathodes and anodes and function as switching elements. A scanning circuit selects the switching elements row by row through the cathodes. A drive circuit writes signal voltages through the selected switching elements into the respective liquid crystal pixels via the transparent electrodes. The drive circuit distributes pulses having pulse heights corresponding to the signal voltages to the liquid crystal pixels, and controls the pulses so that the product of the pulse height and the pulse width is the same for all the pulses.
