Zusammenfassung:	PROBLEM TO BE SOLVED: To drive an LCD panel and an organic EL panel without providing drivers exclusive to these two panels, respectively. SOLUTION: A controller of a panel driver 107 discriminates which display color should be used to display information to be displayed, and the controller indicates a driving method corresponding to this display color to a driving method control circuit 107b and indicates a driving voltage corresponding to the display color to a driving voltage control circuit 107c. The driving method and the driving voltage suitable for the display color are selected by the above processing, and as a result, an CD 112 and an organic EL panel 111 can be simultaneously driven by one panel driver 107.
