The common electrode includes a plurality of divided electrode portions that is extended in a lateral direction and aligned with each other in a longitudinal direction. Each of the plurality of common lines is electrically connected to at least one of the divided electrode portions. The plurality of common lines is arranged in an area next to the common electrode in the lateral direction of the common electrode, arranged next to each other in a width direction orthogonal to a length thereof, is different in width from each other, and the width of the common lines is wider as the length is longer.
