An active matrix liquid crystal display includes a rectangular array of picture elements driven by data and scan drivers. Each picture element includes a liquid crystal display element connected to the output of a unity gain buffer amplifier. The input of the amplifier is connected to a hold capacitor and to series connected gate transistors. The gates of the transistors are connected to a scan electrode and the transistors are connected in series between a data electrode and the input of the amplifier. The output of the amplifier is connected to the connection between the transistors.
