A display panel includes a substrate on which a first display area and a second display area are defined, where the second display area is at least partially surrounded by the first display area and including a sub display and transmission areas, first display devices on the substrate in the first display area, second display devices on the substrate in the sub display area, a first scan line extending from the first display area into the second display area across one side of the second display area, a first sub scan line in the second display area and including a first end facing the first scan line, a first bridge line electrically connecting the first scan line to the first sub scan line, and a bottom metal layer disposed between the second display devices and the substrate in the second display area. The bottom metal layer does not overlap the first scan line when viewed from a direction perpendicular to the substrate.
