Liquid crystal display device having counter electrode with overlapping relation with drain line and extends in region of light-blocking film

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 a first and second substrate 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 the gate lines, at least a counter electrode and at least a pixel electrode formed on the first substrate in each pixel; and at least a light blocking film formed on one of the first and second substrate. The light blocking film is arranged substantially parallel to the gate line and each light blocking film is spaced from and in overlapping relation with the drain line. At least one counter electrode has an overlapping relation with the drain line in plan view and extends in a region of the light blocking film. The counter electrode is made of a transparent conductive layer, and the liquid crystal display device has a normally black mode.
