Display device

A display device including: an image acquisition unit configured to acquire captured images using cameras that capture an image of surroundings of a vehicle; a composite image generation unit configured to synthesize the captured images and generate a composite vehicle image representing the vehicle as viewed from a virtual viewpoint; and a display control unit configured to display the composite vehicle image on an in-vehicle display unit. The composite image generation unit generates the composite vehicle image based on a direction relative to the vehicle from the virtual viewpoint to represent a door of the vehicle as being more widely opened when the virtual viewpoint is located in a predetermined first direction than when the virtual viewpoint is located in a predetermined second direction, the second direction being a direction from which an opening area of the door is more visible from the virtual viewpoint than from the first direction.
