Abstract
A display panel is provided. The display panel includes a substrate and a plurality of cutting rulers. The substrate includes a non-display area and a border surrounding the non-display area. The border includes at least one curved edge and at least one straight edge. The cutting rulers are disposed adjacent to the border. The numbers of the cutting rulers are determined according to the accuracy requirements and the shape of the display panel to meet various needs and improve productivity and product yield.
