The present application discloses a display panel including flexible substrates on which first power lines are mounted to supply power; a substrate including a first surface provided with a display area, a second surface opposite to the first surface, and second power lines for connecting the first power lines to the display pixels; a thermal conduction member partially covering the second surface and conducting heat in an in-plane direction; and a thermal conduction seal covering a periphery of the thermal conduction member. The first surface includes an arrangement area to arrange the second power lines between the flexible substrates and the display area. The second surface includes a first area opposite to the display area and a second area opposite to the arrangement area. The thermal conduction member covers at least the first area. The thermal conduction seal covers the second area.
