PROBLEM TO BE SOLVED: To improve operability of a user who selects hierarchically associated option images.SOLUTION: A display device includes: a display unit 81 having a display area P for displaying option images D1-D3; a display control unit 12 that displays images constituting the option images, which are formed of the images hierarchically associated with each other, sequentially in the display area P according to the hierarchical association; a distance detection unit 82 which detects spatial distance Z between a pointer and the display area P; and a coordinate detection unit 83 which detects coordinates corresponding to the position of the pointer in the display area P. When the spatial distance Z detected by the distance detection unit 82 is shorter than a threshold distance, the display control unit 12 displays, in the display area P, a related image which is an image located in the next lower layer and associated with a specified image which is displayed in a position of the coordinates detected by the coordinate detection unit 83, together with the specified image. |
