Abstract:
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.

Claim (Index 1):
A display apparatus comprising:\n a first display panel having a plurality of pixels and configured to emit nonpolarized first display light; a second display panel having a plurality of pixels and configured to emit nonpolarized second display light in a wavelength range different from that of the first display light; a synthesis optical system which includes a first dichroic mirror that passes one of the first display light emitted from the first display panel and the second display light emitted from the second display panel and reflects the other to thereby synthesize the first display light and the second display light; and a plate-shaped light guiding section which has a first surface extending from a first end to a second end in a first direction and a second surface facing the first surface on a first side in a second direction, which is perpendicular to the first direction, and extending from the first end to the second end in the first direction, and is configured to guide synthesized light emitted from the synthesis optical system to be directed from the first end to the second end in the first direction while reflecting the synthesized light between the first surface and the second surface, and to be emitted from the light-emitting section toward the first side in the second direction, wherein the first dichroic mirror is positioned obliquely to a light-emitting surface of the first display panel and a light-emitting surface of the second display panel as viewed in a third direction, which is perpendicular to the first direction and the second direction.
