Abstract: A display system includes a display and a light-transmitting member. The light-transmitting member has light-transmitting properties and is disposed to face a display screen of the display to dissipate heat generated by the display to outside of the display. The light-transmitting member has a higher thermal conductivity than quartz.

Abstract: A display device according to the present disclosure includes a display member, a light transmission member, a light diffusion member, and a plurality of protrusions. The display member has a display surface. The light transmission member is disposed on the display surface side of the display member, has a first surface on a side opposite to the display member and a second surface on the display member side, and has light transparency. The light diffusion member is disposed on a side opposite to the display surface of the display member, and has light diffusion. The plurality of protrusions is provided between the light transmission member and the display member.

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.
