A material includes a layer with a plurality of self-assembled structures comprising compositions. Light emitted from an organic thin film layer is emitted through the wiring region and the emission region. Once this information is established, the printer application program uses that information to alter the tiled output accordingly to produce a seamless image with repeated or tiled patterns of the actual image. Accordingly, the heat generated by the semiconductor chip can be efficiently dissipated via the heat radiation electrode, the metal plate and the second supporting member.
