The present disclosure discloses an array substrate, a liquid crystal display panel and a display device. The array substrate includes: a base substrate, and a first electrode and a second electrode located in a region defined by intersection of two adjacent data lines, a gate line and a common electrode signal line, where the second electrode is located on a side of the first electrode facing away from the base substrate; the first electrode is in a block shape; the second electrode has a symmetry axis perpendicular to the gate line and passing through the center of the second electrode; the second electrode includes: a frame with an opening in a side; an opening side of the frame faces a first type of signal lines; the first type of signal lines are other signal lines than the data lines and signal lines parallel to the data lines.
