ABSTRACT:
An active matrix liquid crystal display apparatus comprises first and second substrates facing each other through a liquid crystal layer. The first substrate has a plurality of scan bus lines, thin film transistors, display electrodes, and reference potential supplying bus lines, and the second substrate has a plurality of stripe-like data bus lines that face the display electrodes. The display electrode has a compensation capacitor for compensating a potential fluctuation occurring in the display electrode after a gate electrode of the thin film transistor is selected. The capacitance of the compensation capacitor is larger during a compensation period than during a storage period in which the gate electrode of the corresponding thin film transistor is not selected.
