The terminals for a display content control signal or product specification control signal of an integrated circuit are all connected to a corresponding pattern of a circuit board. A display content control signal or product specification control signal pattern is provided together in a display device drive signal pattern for input to the display device or display device through a connection member such as a connector, whereby a plurality of kinds of electronic circuits mounting integrated circuits are not required to manufacture/manage and a soldering pattern or switch member for display content switching or product specification switching is excluded from the circuit board. Further, the display content control signal or product specification control signal inputted to the display device or display device through the above route is, in the pattern interconnection in the display device or display device prepared on the basis of each destination, a certain one is formed with a state that the display content control signal or product specification control signal is shorted and another certain one with a state that the display content control signal or product specification control signal is open, thereby making possible to provide a display content switch section or product specification switch section within the display device or display device.
