A liquid crystal display includes a substrate on which a pixel region is defined, a first sub-pixel electrode in the pixel region on the substrate, an insulating layer on the first sub-pixel electrode, a second sub-pixel electrode in the pixel region on the insulating layer, a floating electrode in the pixel region on the insulating layer and disconnected from the second sub-pixel electrode, a liquid crystal layer on the second sub-pixel electrode and the floating electrode, and a common electrode disposed on the liquid crystal layer. The floating electrode includes first to fourth floating electrodes in first to fourth quadrants of the pixel region, respectively. The first to fourth floating electrodes are separated from one another, and the first sub-pixel electrode partially overlaps the second sub-pixel electrode and the first to fourth floating electrodes.

A thin film transistor substrate, wherein the moving area of electrons between source and drain electrodes of a thin film transistor (TFT) is minimized, the moving distance of electrons is increased, and the sizes of capacitors defined by a gate electrode together with the respective source and drain electrodes are identical to each other so that an off current generated when the TFT is off can be minimized; a method of manufacturing the thin film transistor substrate; and a mask for manufacturing the thin film transistor substrate. Accordingly, it is possible to minimize an off current induced due to a phenomenon of electron trapping by light.
