A dichroic prism synthesizes display light emitted from a plurality of display panels, and a plate-shaped light guiding section guides the synthesized light to a light-emitting section. In the display light emitted from the respective pixels of the display panel, although a radiation angle of an effective luminous flux which reaches the eye of an observer is large in a direction corresponding to the vertical direction, a range of incident angle of intersecting effective luminous fluxes to the dichroic mirror is small.
