1. A display device, comprising:

  • a transmission/reception section that is connected to an other display device, and transmits and receives information to/from the other display device connected thereto;

    a setting input section that enables setting and input of relative position information about a relative position between a partial image displayed by the display device and the partial image displayed by the other display device connected thereto; and

    a first control device that generates partial image information from original image information, and makes a display section to display thereon a partial image based on the partial image information, whereinthe other display device includes a second control device separate from the first control device;

    each of the first and second control devices includes;

    a related information transmission control section that transmits, via the transmission/reception section, position-sequence-related information related to the relative position information set and input to the setting input section;

    a configuration position recognition section that recognizes, based on the position-sequence-related information of the display device, and based on any received position-sequence-related information of the other display device, an absolute position of the partial image in the original image that is supposed to be displayed by the display device; and

    a partial image information generation section that generates, based on the absolute position recognized by the configuration position recognition section, the partial image information by cutting out at least a part of image information from the original image information; and

    the first control device further includes;

    a connection status detection section that detects a connection status of the transmission/reception section;

    an identification information transmission control section that transmits, via the transmission/reception section, identification information assigned to the display device in accordance with the connection status detected by the connection status detection section; and

    a connection sequence recognition section that recognizes a connection sequence of the display device with the other display device based on at least either the connection status detected by the connection status detection section or the received identification information,the position-sequence-related information provided by the related information transmission control section is also related to connection sequence information about the connection sequence recognized by the connection sequence recognition section.
