Plural controller circuits capable of mutually exchanging data are used as a display controller, the plural controller circuits connected to each other via a data bus. Each of the controller circuits, which receives image data, (i) transfers image data other than image data of a screen region, driving of which the controller circuit is in charge of controlling, on the other hand, (ii) stores, into a line memory section thereof, the image data of the screen region, driving of which the controller circuit is in charge of controlling together with image data that is transferred from another controller and that is for the screen region, driving of which the controller circuit is in charge of controlling, and converts the thus stored image data into output image data. This makes it possible to establish common use of a display controller for different resolutions so as to provide cost merit.
