  • Patent number: 7319502
    Abstract: A multi-domain IPS (in-plane switching) liquid crystal display (20) includes a first substrate (201), a second substrate (202), liquid crystal molecules (203) filled between the first and second substrates, and gate lines (211) and data lines (212) formed on the first substrate. The gate lines and data lines define pixel regions arranged in a matrix. Each pixel region includes pixel electrodes (233), common electrodes (243), and a TFT (thin film transistor) (220). The pixel electrodes and the common electrodes have a same curved shape with at least two different bend portions, and are uniformly spaced apart from each other. Therefore the electric field generated by them is a smooth continuum of multiple domains, and the visual performance at various different viewing angles is equally good. Because the pixel and common electrodes do not have sharp bends, disclination is avoided. Therefore the IPS liquid crystal display has a high contrast ratio.

    Abstract: An LCD device (2) includes two substrates (21, 22), a liquid crystal layer (27) therebetween, and gate lines (24) and data lines (23) formed on one of the substrates thereby defining pixel regions. A set of pixel electrodes (26) and a set of common electrodes (25) are provided in each pixel region. The pixel and common electrodes are shaped as hollow rectangles, and are alternately nested one within the other. When a voltage is applied, a horizontal electric field in two different directions (281, 282) is established. Liquid crystal molecules of the liquid crystal layer are twisted according to the two directions, thereby reducing color shift.
