PROBLEM TO BE SOLVED: To provide a projection display device that can easily execute color shift adjustment in good balance over the entire image in a short time.SOLUTION: A projection display device includes: image creation means for creating images; shift means for moving lens means including a lens in a direction orthogonal to the optical axis; first detection means for detecting the position of the shift means; and control means for determining one adjustment position on the basis of the position of the lens in the optical axis direction, the position of the shift means in the direction orthogonal to the optical axis, and color shift information that changes according to the position of the lens and the position of the shift means. The control means determines one adjustment position so that the amounts of color shift at a plurality of correction target positions set on a projection screen are reduced by reducing the amount of color shift at the one adjustment position.SELECTED DRAWING: Figure 1 |
