    摘要： A liquid crystal display unit in which a voltage is applied to a pixel electrode and a common signal electrode constituted by two upper and lower transparent conductive layers having insulation layers disposed therebetween so that a liquid crystal is driven to control display can improve any one or both of reduction of a writing time of the liquid crystal (reduction of a capacitance between the pixel electrode and the common signal electrode) and reduction of a driving voltage of the liquid crystal. An inter-layer insulation layer between the transparent electrodes formed of different layers is constituted by at least one or a laminated structure of a part of a gate insulation layer, a part of a surface protection layer of a thin film transistor and an applied-type insulation layer and insulation layers in an area which is positioned above the lower transparent electrode.

    摘要： 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.
