Abstract: Different groups include the same type of control lines. The first control lines are arranged such that control lines of different types belonging to each of group are adjacent to each other. In the second area, the second control lines are arranged such that control lines of different types belonging to each group are adjacent to each other. In the non-display area, the second control lines are arranged such that control lines of the same type belonging to different groups are adjacent to each other. The capacitor electrode includes portions connected to each other and arranged in the second direction. Each portion faces each other for control lines of the same type adjacent in the non-display area. Any of the portions and any of the other portions differ in width in the first direction.
