ABSTRACT:
A liquid crystal display device can suppress the local temperature elevation of a liquid crystal in the vicinity of drivers. On a liquid-crystal-side surface of one substrate out of substrates which are arranged to face each other in an opposed manner while sandwiching a liquid crystal therebetween, a switching element which is operated in response to scanning signals from a gate signal line, a pixel electrode to which video signals from a drain signal line are supplied via the switching element, and a reference electrode which generates an electric field between the reference electrode and the pixel electrode are mounted on each pixel region of the liquid-crystal-side surface. The video signals from the drain signal line are generated by a driver chip mounted on one substrate. A light transmittivity of the liquid crystal layer is set to take a minimum value when a voltage is not applied between the pixel electrode and the reference electrode. A maximum amplitude of voltage of the video signals is set to a value not more than a voltage necessary for setting a relative transmittivity of the liquid crystal layer to 90%.
