Disclosed is an in-plane switching mode liquid crystal display, in which a pixel electrode and a common electrode are formed on the same substrate. The display includes a first substrate having a first conductive layer and second conductive layer, the first conductive layer and second conductive layer formed on each surface of the first substrate; a second substrate has a transparent pixel electrode and a transparent common electrode formed on one surface of the second substrate, facing the second conductive layer; an electrical connection part is installed to electrically connect the second conductive layer to the transparent common electrode, wherein a common voltage applied to the transparent common electrode is applied to the second conductive layer through the electrical connection part. This arrangement prevents generation of static electricity to suppress a whitening phenomenon due to liquid crystal polarization in a liquid crystal layer, thereby improving display image quality.
