Abstract:
A display apparatus includes a display panel and a data driving part. The display panel includes pixels, data lines and gate lines. A transverse side of the pixels is disposed adjacent to the data lines extending along a first direction, and a longitudinal side of the pixels is disposed adjacent to the gate lines extending along a second direction. Two adjacent pixels of the pixels disposed adjacent to each other along the second direction are connected to one gate line of the gate lines. The data driving part transmits two-dot-inversed first direction data voltages to pixels disposed along the second direction and two-dot-inversed second direction data voltages to pixels disposed along the first direction.

A transistor includes a control electrode, a first current electrode and a second current electrode. The control electrode includes a body portion, and first and second hand portions protruded from first and second ends of the body portion, respectively. The first current electrode is electrically insulated from the control electrode and disposed over a region between the first and second hand portions of the control electrode. A portion of the first current electrode is overlapped with a portion of the control electrode. The second current electrode is electrically insulated from the control electrode and partially overlapped with the body portion, the first hand portion and the second hand portion of the control electrode. Therefore, parasitic capacitance is reduced.

Abstract:
In a liquid crystal display, a liquid crystal panel includes a plurality of pixels. Each of the pixels has a plurality of subpixels corresponding to a red, a green and a blue and is arranged along data lines. The subpixels are formed in pixel regions, which are defined by the data lines and gate lines. First groups of the subpixels are connected to an adjacent left data line and second groups of the subpixels are connected to an adjacent right data line. The data lines are driven by a column inversion driving method such that image data applied to the adjacent data lines have different polarities. Thus, the screen-defects are reduced when the liquid crystal panel is driven by the dot inversion method.

Abstract:
Gate-driving circuitry of a thin film transistor array panel is formed on the same plane as a display area of the transistor array panel. The gate-driving circuitry includes driving circuitry and signal lines having apertures. Thus, a sufficient amount of light, even though illuminated from the thin film transistor array panel side, can reach a photosetting sealant overlapping at least in part the gate-driving circuitry. The thin film transistor array panel and the counter panel are put together air-tight and moisture-tight. Consequently, the gate-driving circuitry can avoid corrosion by moisture introduced from outside. Gate-driving circuitry malfunctions can also be reduced.
