Abstract
An optical path of image displaying light projected from an image displaying face of a display element is changed by a combiner, which is to be arranged in front of an observer. A virtual image, that is a subject of observation, is formed in front of the combiner. An optical component facing the image displaying face is provided so that the image displaying light is introduced to the combiner. The optical component is capable of diverging incident light.
