    • A liquid crystal display that is subject to pixel-high defects due to manufacturing anomalies is provided with programmable repair means for each pixel electrode. In one embodiment, a transistor-array substrate is provided with plural gate lines that are separated from each other by a first interval, plural data lines that are insulated from the gate lines while crossing the gate lines, and separated from each other by a second interval larger than the first interval, thereby defining plural pixel areas. Each pixel area has a corresponding pixel unit comprising a switching device, pixel electrode, and repair electrode. The repair electrode branches from a neighboring gate line and extends such that the repair electrode is in overlapping spaced-apart relation with the pixel electrode and selectively connectable to the pixel electrode. Accordingly, a pixel where a high pixel defect occurs can be repaired by selective connection with the repair electrode, thereby improving display quality of the liquid crystal display.
    • 由于制造异常而受到像素高缺陷的液晶显示器,为每个像素电极提供可编程修复装置。 在一个实施例中,晶体管阵列基板设置有多条栅极线,它们彼此分开第一间隔,多条数据线在与栅极线交叉的同时与栅极线绝缘并且彼此分开第二个 间隔大于第一间隔,从而限定多个像素区域。 每个像素区域具有包括开关器件,像素电极和修复电极的对应像素单元。 修复电极从相邻的栅极线分支并延伸,使得修复电极与像素电极重叠间隔开,并且可选择性地连接到像素电极。 因此,可以通过与修复电极的选择性连接来修复发生高像素缺陷的像素,从而提高液晶显示器的显示质量。
