  • Publication number: 20100157186
    Abstract: A liquid crystal display includes a first substrate and a second substrate facing the first substrate, a gate line and a data line disposed on the first substrate, and a pixel electrode disposed on the first substrate. The pixel electrode is connected to the gate line and the data line, and includes subregions. The liquid crystal display further includes a storage electrode disposed on the first substrate overlapping the pixel electrode to form a storage capacitor, a common electrode disposed on the second substrate, and a liquid crystal layer interposed between the pixel electrode and the common electrode and including liquid crystal molecules disposed therein. The pixel electrode includes a stem defining boundaries between the subregions, and a width of the stem changes from a center portion of the pixel electrode to a peripheral portion of the pixel electrode.

  • Publication number: 20100148176
    Abstract: The present invention relates to a thin film transistor array panel that includes an organic layer formed on a data line and a drain electrode disposed on a color filter. A thickness of a portion of the organic layer around a contact hole exposing a portion of the drain electrode is similar to a thickness of a portion of the organic layer around a contact hole exposing a portion of the data line. Having approximately the same thickness can prevent non-uniform etching of the organic layer around contact holes and deterioration of the thin film transistor array panel.

  • Publication number: 20100033418
    Abstract: The present invention provides a liquid crystal display (LCD). The LCD includes: a liquid crystal panel that includes a plurality of gate lines; and a gate driver that includes a plurality of stages, which are connected to the gate lines, respectively, and sequentially provide a plurality of gate signals to the gate lines, respectively, and a first dummy stage and a second dummy stage that are separated from each other, wherein the first dummy stage is enabled by a carry signal of one of the stages, and the second dummy stage is enabled by a carry signal of the first dummy stage and initializes each of the stages.

  • Publication number: 20090244424
    Abstract: A liquid crystal display (“LCD”) capable of improving display quality includes a first insulating substrate, gate wiring lines formed on the first insulating substrate and extending in a first direction, pixel electrodes, each of which includes first and second sub-pixel electrodes that are, respectively, applied with different data voltages from first and second wiring lines insulated from and crossing the gate wiring lines, extending in a second direction and an insulting layer interposed between the first data wiring line and the second data wiring line overlapped by the first data wiring line. Therefore, an aperture ratio of the LCD increase because the first data wiring line overlapped the second data wiring line have less area between pixel electrodes. A display quality of the LCD improves.
