ABSTRACT:
An exemplary liquid crystal display (LCD) (20) includes a plurality of scanning lines (21) that are parallel to each other and that each extend along a first direction, and a plurality of data lines (2) that are parallel to each other and that each extend along a second direction different from the first direction. Each scanning line includes a first sub-line (211), a second sub-line (212), and a plurality of connecting portions (213) electrically connecting between the first and second sub-lines. The scanning lines of the LCD each include the first and second sub-lines connected in parallel. Thus the scanning lines have a low resistance. When scanning voltages flow through the scanning lines, any voltage drop is relatively small, and all TFTs (23) of the LCD connected with a same scanning line can be driven by substantially the same voltage. Therefore, the LCD has improved display performance.
