Abstract: A display device includes: a resin layer on the circuit layer including a groove surrounding and separating a display area; light-emitting elements on an upper surface of the resin layer so as to emit light with luminances controlled by the currents; a sealing layer covering the light-emitting elements; a second substrate above the sealing layer; a sealing material provided between the sealing layer and the second substrate so as to surround the display area and the groove; and a filling layer surrounded by the sealing material between the sealing layer and the second substrate. The groove is formed along a line describing a shape that is inscribed in a rectangle and not in contact with corners of the rectangle as viewed in a direction vertical to the upper surface of the resin layer.
