Abstract
A thin film transistor substrate and a liquid crystal display capable of eliminating residual images and enhancing clarity are presented. The thin film transistor substrate includes a charge-up capacitor for increasing electric charge in a first pixel electrode of a first pixel capacitor and a charge-down capacitor decreasing electric charge in a second pixel electrode of a second pixel capacitor. An extension electrode portion of the charge-up capacitor is formed in the shape of a frame to reduce any variation in the overlapping area between the first pixel electrode and the extension electrode portion caused by an alignment error generated during the manufacturing process.
