Abstract

An LCD capable of being reduced by a whole size and a defective proportion thereof being minimized. An LCD panel of the LCD includes a gate driving circuit that drives gate lines formed extended along a row direction and a line block selecting circuit that drives data lines extended along a column direction. On the LCD panel, an integrated driving chip having a controller, a memory, a level shifter, a source driver, a common voltage generator and a DC/DC converter is mounted. The integrated driving chip not only drives the gate driving circuit and line block selecting circuit, but also controls the operation of the LCD panel to display an image. Thus configured, a defective proportion of the LCD is decreased, with the whole size thereof being reduced.
