Abstract
In an in-plane switching (IPS) mode active matrix type liquid crystal display device, data lines supplied with data signals, common electrode wiring portions and applied with a reference voltage, a common electrode , pixel electrodes corresponding to pixels to be displayed, scanning lines supplied with scan signals and TFT's are provided on an active element substrate . The common electrode wiring portions and are formed by using a first metal layer, extend in parallel to the scanning line and connected to a common electrode potential at a peripheral portion thereof. Protruded portions and are formed in at least one of the common electrode wiring portions and in such a way that the protruded portions are positioned on both sides of the data line to be formed later. Unevenness of display of the display device is reduced and the aperture ratio thereof is improved.
