Abstract:
1. A liquid crystal display device, comprising: a first substrate including a plurality of scanning signal wirings, a plurality of video signal wirings, a switching element disposed at each of intersection points of the scanning signal wirings and the video signal wirings and a common signal wiring formed below the video signal wirings; a second substrate opposite to the first substrate; and a liquid crystal layer sandwiched between the first and second substrates, wherein the first substrate further includes pixel electrodes and common electrodes which are formed in a lattice shape such that a plurality of vertical bars are extended between a pair of a horizontal bars, respectively, each of the pixel electrodes are formed integrally with each of one electrodes of the switching elements and have a removed portion at an external periphery of one of the horizontal bars, and the common electrodes are connected to the common signal wiring through contact holes located at the horizontal bars of the common electrodes; and wherein the removed portion is provided at the horizontal bars of the pixel electrodes near the contact holes, and the horizontal bars of the pixel electrodes form storage capacitors through the common signal wirings and a first insulating foam.
