(a) Technical Field
The invention relates to a liquid crystal display.
(b) Description of the Related Art
A liquid crystal display, which is one of flat panel displays which have been widely used, is a display which includes two display panels in which field generating electrodes are disposed, and a liquid crystal layer interposed therebetween to apply a voltage to the electrode so as to change directions of liquid crystal molecules of the liquid crystal layer, thereby controlling transmittance of light passing through the liquid crystal layer.
In the liquid crystal display, a pixel electrode and a common electrode which generate an electric field applied to the liquid crystal layer may be disposed in a single display panel in which a switching element is further disposed.
When the pixel electrode and the common electrode which generate the electric field in the liquid crystal layer are disposed in the single display panel of the liquid crystal display, the pixel electrode and the common electrode overlap each other, having an insulating layer disposed therebetween. As a size of the liquid crystal display is increased, an overlapping area between the pixel electrode and the common electrode is increased and thus storage capacitance is increased to a desired value or more, such that charging a desired amount of electrical charge in the pixel electrode may take a relatively large amount of time, thereby causing a signal delay in the liquid crystal display.
