摘要： In an in-plane switching (IPS) mode active matrix type liquid crystal display device, data lines 24 supplied with data signals, common electrode wiring portions 26a and 26b applied with a reference voltage, a common electrode 26, pixel electrodes corresponding to pixels to be displayed, scanning lines 28 supplied with scan signals and TFT's 50 are provided on an active element substrate 11. The common electrode wiring portions 26a and 26b 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 299a and 299b are formed in at least one of the common electrode wiring portions 26a and 26b in such a way that the protruded portions are positioned on both sides of the data line 24 to be formed later. Unevenness of display of the display device is reduced and the aperture ratio thereof is improved.

摘要： An in-plane switching mode active matrix type liquid crystal display device includes a first substrate, a second substrate located opposing the first substrate, and a liquid crystal layer sandwiched between the first and second substrates. The first substrate includes a thin film transistor, a pixel electrode each associated to a pixel to be driven, a common electrode to which a reference voltage is applied, data lines, a scanning line, and common electrode lines. Molecular axes of liquid crystal are rotated in a plane parallel with the first substrate by an electric field substantially parallel with a plane of the first substrate to thereby display certain images. The common electrode is composed of transparent material and are formed on a layer located closer to the liquid crystal layer than the data lines. The common electrode entirely overlaps the data lines except an area where the data lines are located in the vicinity of the scanning line. The liquid crystal display device further includes a light-impermeable layer in an area where the common electrode entirely overlaps the data lines. The light-impermeable layer is comprised of a black matrix layer having a width smaller than a width of the common electrode.

摘要： An active-matrix addressing LCD device using lateral electric field realizes a higher transmittance and a higher fabrication yield and improves the aperture ratio without raising the fabrication cost. A first one of the common electrode lines, a first one of the pixel potential layers, and an intervening dielectric layer constitute a first storage capacitor for each of the pixels and at the same time, a second one of the common electrode lines, a second one of the pixel potential layers, and the intervening dielectric layer constitute a second storage capacitor for the same pixel. The first and second pixel potential layers are electrically connected to each other by way of a corresponding transparent pixel electrode. Therefore, the rotation of the liquid crystal molecules caused by applied electric field makes full contribution to the panel transmittance, preventing the obtainable total panel transmittance from lowering. This means that a higher transmittance is obtainable. An interconnection electrode may be additionally provided for the same purpose.

摘要： A LCD device includes a plurality of pillar spacers disposed within liquid crystal for achieving a uniform cell gap between the color filter panel and the TFT panel of the LCD device. The pillar spacers are formed on the color filter panel and abut the TFT panel at a portion of the gate electrode exposed from an opening of an organic overcoat.
