There is provided a display device with which the density of ship traffic can be intuitively ascertained, without the display looking complicated even in areas through which ships frequently pass. This ship display device comprises a past track storage component and a display component. The past track storage component stores information related to the past tracks of ships. The display component graphically displays a track density distribution, which is a density distribution of the past tracks. More specifically, the display component displays the track density distribution with a grid divided up in regular intervals. The colors of the sections varies to change from one color to another as the density of the past tracks increases.
