Abstract

An active device array substrate is provided. The active device array substrate comprises a substrate, multiple first lines, second lines, active devices, pixel electrodes and common lines. The first lines and second lines are disposed on the substrate and they form multiple pixel regions on the substrate. The active devices are respectively disposed in the pixel regions and each of the active devices is electrically connected to a first line and a second line, respectively. The pixel electrodes are respectively disposed in the pixel regions and each of the pixel electrodes is electrically connected to an active device, respectively. The common lines and first lines are roughly parallel and they are staggeringly disposed on the substrate. Each of the common lines has multiple branches which extend outside from their edges of two sides, and each of these branches is partly overlapped with the second lines.
