Abstract

A display panel includes a flexible substrate, a first display region, a second display region, and a third display region. The first display region has a quadrangle outline and includes a first side and a second side forming a first corner portion of the outline. The second display region is in contact with the first side and the width of the second display region in a direction parallel to the first side coincides with the length of the first side. The third display region is in contact with the second side and the width of the third display region in a direction parallel to the second side coincides with the length of the second side. The substrate includes a notch portion corresponding a region facing the first display region with the first corner portion provided therebetween.
