A display device includes a front side and a rear side. It is furthermore provided that the gate regions are formed such that they are electrically coupled to one another via a capacitor configuration. A robot camera acquires continuous image information by means of a camera rotatable by a motor. The present invention solves this problem in that the tool head is connected to the handle without crossing over itself. The method for thermocompression bonding, includes: preheating a resin member using an infrared radiation section; and subjecting the resin member to thermocompression bonding using a heating section and a pressurization section. In the configuration, among the two sets of inverter circuits, one set of inverter circuit is formed by a circuit connecting an organic electoluminescent device and a transistor in series, and a transistor of a memory circuit is omitted.
