A display system includes a display processing device that controls display of an image, a posture detection device that detects a posture change amount of moving body, a correction processing device that sets a correction amount of display position of the image, a display determiner that determines whether or not to display the image, and a gradient change detector that detects a gradient change of a traveling path. The gradient change detector detects that a posture change of the moving body is started when an absolute value of the posture change amount is larger than a first threshold, and that the posture change is completed when the absolute value becomes smaller than a second threshold after start of the posture change. The display determiner determines not to display the image from start of the posture change until completion of the posture change.
