A display device, comprising:
- an intermediate-image formation unit configured to form an intermediate image on a screen;
- a projection unit configured to project the intermediate image toward a member to display a virtual image, wherein the member transmits a portion of incident light flux and reflects a remaining portion of the incident light flux;
- circuitry configured to receive virtual image information about the virtual image, and rotate the intermediate image within the screen to correct a defect of the virtual image, based on the received virtual image information,
- wherein the defect includes tilt or distortion of the virtual image, and the circuitry is further configured to rotate the intermediate image so that the virtual image is less tilted or distorted.
