  • Publication number: 20040109099
    Abstract: Disclosed is a liquid crystal display capable of high quality image and bright display. Gate signal lines are curved at near switching elements of the liquid crystal display. A pixel area is defined by the gate signal lines and their intersecting data signal lines. Pixel electrodes and common electrodes are disposed along a longitudinal direction of a pixel. A pixel signal and a common signal line is connected to the pixel electrode and the common electrode respectively. A storage capacitor may be formed in the middle of a longitudinal direction of the pixel, or where generally a texture may arise during display. One half of the pixel may be symmetrical with the other half with respect to the storage capacitor. A common signal line may be parallel with the data signal line and be disposed nearer to the data signal line than a pixel signal line. The pixel may be disposed symmetrically with respect to the data signal line therebetween.

  • Publication number: 20040090578
    Abstract: A TFT array panel on which both pixel electrodes and common electrodes are formed and a color filter panel is disposed opposing the array panel, and liquid crystals are interposed therebetween. The liquid crystals are aligned parallel to the two panels and driven by parallel electric field formed between the pixel electrodes and reference electrodes. Polarization films are arranged outsides the two panels, and a quasi-A plate compensation film is arranged between the color filter panel and the polarization film.

  • Publication number: 20040004689
    Abstract: Liquid crystal material is interposed between an upper panel and a lower panel. The lower panel includes signal transmitting wires including a gate wire and a data wire, thin film transistors connected to the signal transmitting wires and pixel electrodes connected to the thin film transistors, and the upper panel includes color filters, a black matrix and a common electrode. The pixel electrodes and the common electrode have apertures partitioning the pixel electrode into several domains. In addition, the director of liquid crystal molecules contained in the liquid crystal material is aligned perpendicular to the upper panel and the lower panel in absence of electric field between the pixel electrodes and the common electrode. The dielectric anisotropy of the liquid crystal material has a value ranging −4.0 to −5.5.
