  • Patent number: 7847907
    Abstract: A display substrate, a method of fabricating the same, and a liquid crystal display apparatus having the same. The display substrate includes a storage electrode extending over first and second areas formed on a substrate, a insulating layer pattern formed on the storage electrode, and first and second pixel electrodes formed on the insulating layer pattern. At least one of the first and second pixel electrodes has at least one recess. The insulating layer pattern has first and second openings formed in the first and second areas corresponding to the storage electrode. Accordingly, electric short circuits between the first and second pixel electrodes is prevented due to the recess or the openings during the manufacturing process for the first and second pixel electrodes.

  • Patent number: 7515233
    Abstract: “A liquid crystal display of the present invention comprises a first substrate, a second substrate and a liquid crystal layer injected there between. The first substrate has first base plate, a gate line formed on the first base plate, a data line formed over the gate line, a switching element electrically connected to the gate line and the data line, a pixel electrode electrically connected to the switching element, an element dividing LC domains formed on the pixel electrode, first alignment layer formed on the domain dividing element. The second substrate comprises second base plate, a common electrode formed on the second base plate, a first protrusion and a second protrusion formed on the common electrode. The first protrusion and the second protrusion have different heights. A second alignment layer is formed on the protrusions.

  • Publication number: 20080316411
    Abstract: An array substrate includes light blocking parts formed under a semiconductor line. The light blocking parts have an electric potential lower than a critical electric potential, at which a short occurs, thereby minimizing the electric potential difference between the light blocking parts and the adjacent lines when an electrostatic field is applied to the light blocking parts.
