Abstract
The invention discloses a liquid crystal display capable of preventing color shift and also improving response time characteristics. The liquid crystal display comprises: an upper substrate and a lower substrate opposed to each other with a selected distance; a liquid crystal layer sandwiched between the upper and the lower substrate, and having a plurality of liquid crystal molecules; a pixel electrode formed at an inner surface of the lower substrate, wherein a display signal is applied to the pixel electrode; and a counter electrode formed an inner surface of the upper substrate and forming an electric field together with the pixel electrode by applying a common signal, thereby driving the liquid crystal molecules; wherein a voltage difference is occurred between the counter and the pixel electrodes, there are simultaneously formed an electric field disposed vertical to substrate surface and an oblique electric field disposed oblique to substrate surface between the pixel electrode and the counter electrode.
