PROBLEM TO BE SOLVED: To provide the thick line display device which can be improved in the display precision of a thick line without exerting any influence on the display speed by displaying a correction circle at a gap part. SOLUTION: The thick line display device which generates and displays the thick line having width in a specific direction for the reference line connecting a start and an end point at a display means is equipped with intersection judging means 12 and 13 which judge whether or not the start point or end point of the reference line is an intersection with another reference line, radius calculating means 12 and 13 which calculate the radius of the correction circle for correcting the gap part at the intersection of the reference line and the other reference line from the line width of the thick line generated from the reference line, and correction circle display means 14, 15, and 16 which display the correction circle having the radius calculated by the radius calculating means at the display means so that the circle has its center at the intersection. |
