Abstract: The displaying system includes a display unit, a projection unit, and a light-transmissive member. The display unit is configured to display an image. The projection unit is configured to reflect rays of light constituting the image toward a reflective member to project the image onto the reflective member to form a virtual image in a target space. The light-transmissive member has a plate shape. The light-transmissive member is located between the reflective member and the projection unit. The light-transmissive member intersects with an optical axis of light traveling from the projection unit toward the reflective member without forming right angles. The light-transmissive member has in-plane retardation and thickness direction retardation larger than the in-plane retardation.

Abstract: A display device includes a light source, an optical system, a liquid crystal panel, and a first heat sink. The optical system converts light emitted from the light source into irradiation light that is to be an irradiation area having a predetermined width. The liquid crystal panel receives the irradiation light. The first heat sink includes an opening through which the irradiation light passes, and supports the liquid crystal panel. The first heat sink is in contact with the liquid crystal panel.
