Abstract
In a liquid crystal display device, gate lines and common lines are first concurrently formed, and after an interlayer film is formed, a pixel electrode, common electrodes, and source lines are formed at the same time. By this, a electrode pattern can be made simple and manufacturing steps are simplified. Further, wiring lines and electrode disposed in the layer closest to a liquid crystal layer are made the pixel electrode, common electrodes and source lines, and the shapes thereof are made simple.
