A fuel tank disposed on a lower face of a floor panel beneath a driver’s seat and a passenger’s seat. The memory card contacts and the module contact are electrically separated. The thickness of the second hole transporting layer is approximately one-third to two-thirds of an optical wavelength difference between the first and second pixel regions, and the thickness of the third hole transporting layer is approximately one-third to two-thirds of an optical wavelength difference between the second and third pixel regions.
