A head-up display device includes a display element, a movable mirror, one or more first and second mirrors, and an movable unit. The display element emits light to form a display image. The movable mirror first reflects light emitted from the display element. The one or more first and second mirrors reflect light reflected off the movable mirror to project a virtual image. The movable unit adjusts a position of the movable mirror to adjust a projection distance of the virtual image. The movable mirror is disposed at a position such that light incident to the movable mirror is non-parallel to a normal of the movable mirror.

A light emitting device emitting an output light includes a light adjustment structure. A sub light is defined as the output light corresponding to an azimuth angle, a first value L1 is a sum of a luminance of the sub light corresponding to a polar angle from 115 to 125 degrees, a second value L2 is a sum of a luminance of the sub light corresponding to a polar angle from 95 to 105 degrees, a third value L3 is a sum of a luminance of the sub light corresponding to a polar angle from 75 to 85 degrees, a fourth value L4 is a sum of a luminance of the sub light corresponding to a polar angle from 55 to 65 degrees. The first value L1, the second value L2, the third value L3 and the fourth value L4 satisfy L3<L2, and 1.23?(L1*L3)/(L2*L4)?2.92.

A motor vehicle includes a passenger display with a switchable view protection device that is actively switched in predetermined operating states so that display contents shown on the passenger display cannot be seen from the seating area of the driver. The vehicle includes a shading device having an illuminant oriented toward the passenger display and is controlled by a control unit and which, in order to prevent moving residual fragments that can still be detected from the driver's seat despite a view protection device which is switched to shading, externally illuminates the passenger display.

Provided is a high decorative illumination device that utilizes a lenticular lens sheet. An illumination device includes a lenticular lens sheet and an LED light source. The lenticular lens sheet is curved in an X direction, and a convex surface is formed in a concave shape. The LED light source is positioned inside the convex surface of the lenticular lens sheet. First and second reflection components from first and second bright points which are acquired by reflecting irradiation light rays from the LED light source from plano-convex cylindrical lenses are incident on left and right eyes of an observer who observes the illumination device. The observer observes a virtual image as if a light emitter is present in a position in which the first and second reflection components cross each other.
