To provide a display system that can reduce variations in luminance of a virtual image with respect to shape deviation during processing on the contour of a light transmission member and positional deviation between a display unit and the light transmission member during attachment, and a movable body.SOLUTION: A display system 10 comprises: a display unit 110; a projection unit 120; and a light transmission member 130. The display unit 110 displays an image. The projection unit 120 reflects light beams forming the image toward a reflection member 101 to project the image on the reflection member 101 and projects a virtual image 310 n an object space 400. The light transmission member 130 has a plate-like shape. The light transmission member 130 is between the reflection member 101 and projection unit 120. The light transmission member 130 is not orthogonal to and intersects an optical axis L10 of a light beam directed from the projection unit 120 to the reflection member 101. The light transmission member 130 has a thickness direction phase difference larger than in-plane phase difference.SELECTED DRAWING: Figure 1
【課題】課題は、光透過部材の外形加工時の形状ずれや、取付時の表示部と光透過部材との位置ずれに対する虚像の輝度の変動を低減できる、表示システム及び移動体を提供することである。【解決手段】表示システム10は、表示部110と、投影部120と、光透過部材130と、を備える。表示部110は、画像を表示する。投影部120は、画像を構成する光線を反射部材101に向けて反射して反射部材101に画像を投影して対象空間400に虚像310を投影する。光透過部材130は、板状である。光透過部材130は、反射部材101と投影部120との間にある。光透過部材130は、投影部120から反射部材101に向かう光線の光軸L10と直交せずに交差する。光透過部材130は、面内位相差よりも大きい厚さ方向位相差を有する。【選択図】 図1
