Abstract
There is provided a liquid crystal display device in which light leaks near spacers are prevented. The liquid crystal display device controls the optical transmissivity of a liquid crystal layer interposed between substrates disposed in opposition to each other, by means of an electric field generated in the layer-thickness direction of the liquid crystal layer, includes spacers formed on a liquid-crystal-side surface of one of the substrates, signal lines formed on a liquid-crystal-side surface of the other substrate, an insulating film formed to cover the signal lines, and electrodes formed on the upper surface of the insulating film, each of which serves as one electrode contributing to control of the optical transmissivity of the liquid crystal layer. Each of the spacers has a vertex surface disposed in opposition to any of the signal lines, and a portion of each of the electrodes is extended to the upper surface of a corresponding one of the signal lines and the extended portion is opposed to a part of the vertex surface of a spacer disposed in opposition to the corresponding one of the signal lines.
