Abstract

A liquid-crystal display apparatus includes first and second substrates sandwiching a liquid-crystal, and having a switching element provided at a cross point of a scan line and a data line on the first substrate, a vertical drive circuit for controlling a voltage of the scan line provided on the first substrate, a horizontal drive circuit for controlling a voltage of said data line provided on the first substrate, and a transparent electrode provided on a surface of the second substrate. The horizontal drive circuit includes a reference-voltage generator, a voltage selector, a controller, and a sample-and-hold arrangement.
