Abstract

An active matrix type liquid crystal display apparatus can be driven with a low voltage, a reduced power consumption rate and a reduced circuit size without sacrificing the quality of the image it displays. It comprises a plurality of vertical signal lines, a substrate carrying thereon a plurality of pixel electrodes connected to the respective crossings of the plurality of vertical signal lines and the plurality of scanning lines by way of respective transistors, a counter electrode substrate carrying thereon a counter electrode and liquid crystal pinched between the substrate and the counter substrate and is characterized in that two transistors of different conductivity types are connected to each of the pixel electrodes and the source electrode or the drain electrode and the gate electrode of the transistor of the first conductivity type are connected respectively to a first vertical signal line and a first scanning line, whereas the source electrode or the drain electrode, whichever appropriate, and the gate electrode of the transistor of the second conductivity type different from the first conductivity type are connected respectively to a second vertical signal line and a se…
