Abstract
PURPOSE:To prevent the damage to a display surface caused by direct exposed sunlight and to always observe information of both of a display element and a luminous flux combining element in a favorable state by installing a light shading member which shades light in a visible area in an optical path between the display element and the luminous flux combining element. CONSTITUTION:The luminous flux from the display information on the display surface 2 of a display element 1 is made nearly parallel through a projecting lens 3 and made incident on the luminous flux combining element 5 held by a transparent window member 5 and the reflected light from the luminous flux combining element 5 or diffracted light of specified number of degree is guided to an observer 10 side. When a power source is disconnected and actions are stopped, the surface of the projecting lens 3 is completely covered with the light shading plate 61 as the light shading member which shades the light in the visible area. Even if a device is left in a state where it is directly exposed with the sun light in the daytime, the display surface 2 is favorably protected and scattered light caused by sticking dust on the projecting lens can be prevented from occurring.
