A TFT formed on an insulating substrate source, drain and channel regions, a gate insulating film formed on at least the channel region and a gate electrode formed on the gate insulating film. The display device displays several indicia. The surrounding state detector detects an exit of the vehicle out of a roofed space. Bonding material is disposed both on said first surface and said second surface. The multiple antenna elements are isolated or combined in order to provide a self adjusting electrical length by using multi-terminal filtering.
