  • Patent number: 10139686
    Abstract: The embodiment of the present application discloses an array substrate, a liquid crystal display panel, and a display device, with first common electrode compensation lines being arranged within pixel regions which correspond to pixels provided with a minimal transmittance, by which first common electrode compensation lines a common electrode is charged so as to ensure a constant voltage on the common electrode. Moreover, since the first common electrode compensation lines are configured to overlap neither first signal lines nor second signal lines, a repairmen of the first signal lines or the second signal lines will not be adversely affected in case that there is short-circuit or open-circuit thereon. Besides, since the common electrode compensation lines are arranged within pixel regions provided with the lowest transmittance, the influence onto overall transmittance of the display panel is minimized relatively.
