ABSTRACT:
The charging voltage of a pixel electrode varies when there is a photo-misalignment of the pixel electrode, and such variation degrades the display quality. An array substrate that prevents fluctuation in the charging voltage of a pixel electrode is presented. The array substrate includes a pixel electrode, a gate wiring formed on the pixel electrode, and a data wiring that includes a first data line and a second data line formed two sides of the pixel electrode. A first voltage-maintaining electrode is separated from a first side of the first data line by a first distance, and a second voltage-maintaining electrode is separated from a second side of the first data line by a second distance. Both voltage-maintaining electrodes are electrically connected to the pixel electrode. A thin-film transistor is electrically connected to the gate wiring, the data wiring and the pixel electrode.
