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.
