Liquid crystal display device with first and second reference lines in each pixel

This invention relates to a liquid crystal display device; and, more particularly, the invention relates to a high picture quality image active matrix system liquid crystal display device having thin film transistor elements. An active matrix type liquid crystal display device includes first and second substrates with a liquid crystal layer therebetween, a plurality of drain lines and gate lines formed on the first substrate and crossing each other in a matrix form, a plurality of pixels formed by adjoining the drain lines and adjoining the gate lines, and at least a pixel electrode formed on the first substrate in each pixel, a first reference line is arranged along one of the adjoining gate lines in each pixel, a second reference line is arranged along another of the adjoining gate lines in each pixel, and the pixel electrode crosses only one of the first reference line and the second reference line.
