  • Patent number: 8144289
    Abstract: The present invention discloses a liquid crystal display panel, a thin film transistors array substrate and curing line structure thereof in use of phase separation alignment (PSA) process. The curing line structure has a contact pad allocated on a periphery area of the substrate, and a transmission line extending from the contact pad, passing over a sealant-distributing area of the substrate, to be electrically connected with at least one common line located on a pixel expression area of the substrate. A predetermined interval is kept between the transmission line and each of the adjacent transmission lines on the substrate to ensure a non-electrical contact between the transmission line and the adjacent transmission lines.

  • Publication number: 20100265450
    Abstract: A plurality of spacers are used to control the gap in a liquid crystal display panel. When a spacer is associated with an electrode in the lower substrate where the switching elements and data lines are disposed, it is located substantially at the center of the electrode. In a transflective LCD sub-pixel, a spacer may be disposed at the center of one of the transmissive and reflective electrodes. Alternatively, a spacer is disposed at the center of each of the transmissive and reflective electrodes. When the electrode in a sub-pixel comprises different sections to affect the alignment of the liquid crystal layer associated with the electrode, the spacer is located at the intersection of the sections, if possible, so that the spacer is located at the intersections of different domains of the liquid crystal layer.
