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.

Abstract: An electrolyzed water spraying device of the present disclosure includes: a short-term maintenance water storage portion (30) that stores liquid and requires short-term maintenance; a long-term maintenance water storage portion (31) that stores liquid and requires long-term maintenance; and a notification controller (43) that notifies each of the timing of the next short-term maintenance and the timing of the next long-term maintenance. The notification controller (43) simultaneously performs the notification of the timing of the next short-term maintenance and the notification of the timing of the next long-term maintenance when the timing of the next short-term maintenance and the timing of the next long-term maintenance are close to each other.

Abstract: A projection device includes: a plurality of light sources arranged in a first direction; a spatial modulation element that modulates incident light into image information and emits the image information; a lens that changes an optical path of light emitted from each of the plurality of light sources such that the light emitted from each light source reaches substantially the same region of an incident surface of the spatial modulation element; and a first reflective optical member that deflects the light emitted from the lens toward the spatial modulation element, the first reflective optical member having a shape that reflects light emitted from the lens so as to be incident on an arbitrary point on the incident surface of the spatial modulation element at a predetermined reference incident angle.
