A display device, comprising: a display panel that displays an image, wherein: the display panel is a touch panel capable of detecting an input by a touch input; a case that supports a display surface of the display panel so as to be visible from the exterior; a plurality of connection receiving portions (43, 43A-43D) that electrically connects to an external storage device (50, 50A, 50B) so that the external storage device (50, 50A, 50B) is connected to the display device, the connection receiving portions (43, 43A-43D) being provided to a side surface of the case, each of the connection receiving portions (43, 43A-43D) corresponds to a plurality of types of the external storage devices (50, 50A, 50B), respectively; a connection determination portion that determines whether or not the external storage device (50, 50A, 50B) has been connected to the connection receiving portion (43, 43A-43D); characterised in that the display device further comprises a display processing portion that, in a case where the external storage device (50, 50A, 50B) has been determined by the connection determination portion to be connected, reads a connector image indicative of a connector of the connected external storage device (50, 50A, 50B), and displays, at a position on the display panel that corresponds to a connection receiving portion (43A-43D) to which the connector of the connected external storage device (50, 50A, 50B) is connected, the read connector image, a first input determination portion that determines whether or not a predetermined first input in the form of a touch input has been made at a display position of the connector image on the display panel, wherein in a case where the first input has been determined by the first input determination portion to have been made, the display processing portion displays an icon behind the connector image, the icon corresponding to data stored in the external storage device (50, 50A, 50B); an input determination portion that determines whether or not an input by continuous touch input has been made in one direction in the vicinity of the connector image on the display panel, the one direction comprises a first direction given by a direction of connection of the external storage device (50, 50A, 50B) or a second direction being a direction inverse to the direction of the connection of the external storage device (50, 50A, 50B), where the second direction is a sliding touch input towards the connector image; and an erase processing portion that erases the connector image from the display panel after the erase processing portion has executed an eject process placing the external storage device (50, 50A, 50B) in a removable state in a case where the input by continuous touch input towards the connector image has been determined by the input determination portion to have been made. the display panel is a touch panel capable of detecting an input by a touch input;
