Abstract: There is provided a liquid crystal display (LCD) device that prevents light leaks near spacers. The LCD device controls the optical transmissivity of a liquid crystal layer interposed between substrates disposed opposite each other, by means of an electric field generated in the layer-thickness direction of the liquid crystal layer. The LCD device includes spacers on a liquid-crystal-side surface of one substrate, signal lines formed on a liquid-crystal-side surface of the other substrate, an insulating film formed to cover the signal lines, and electrodes on the insulating film's upper surface. Each electrode contributes to controlling the optical transmissivity of the liquid crystal layer. Each spacer has a vertex surface disposed opposite to the signal lines. A portion of each electrode extends to the upper surface of a corresponding signal line. The extended portion is opposite to a part of a spacer's vertex surface disposed opposite to the corresponding signal line.
