Abstract
An image display apparatus includes a color combining prism configured to combine a plurality of image light components from a plurality of image display elements, a plurality of polarization separating elements disposed on light paths of the plurality of image light components, a plurality of light transmitting members fixed to a plurality of entrance surfaces through which the plurality of image light components enters the color combining prism, and a supporting member configured to support a pair of a light transmitting member and a polarization separating element corresponding to each other out of the plurality of light transmitting members and the plurality of polarization separating elements, wherein the supporting member is disposed on a side surface of the light transmitting member.
Claims14
An image display apparatus comprising:
- a plurality of image display elements corresponding to a plurality of color light components;
- a color combining prism configured to combine a plurality of image light components from the plurality of image display elements;
- a plurality of polarization separating elements each disposed on corresponding one of a plurality of light paths on which the plurality of image light components from the plurality of image display elements travels to the color combining prism;
- a plurality of light transmitting members fixed to a plurality of entrance surfaces through which the plurality of image light components enters the color combining prism;
- and
- a supporting member configured to support a pair of a light transmitting member and a polarization separating element corresponding to each other out of the plurality of light transmitting members and the plurality of polarization separating elements,
- wherein
- surfaces of the color combining prism to which the light transmitting members are disposed are larger than the surfaces of the light transmitting members disposed on the color combining prism,
- and wherein
- the supporting member is disposed on a side surface of the light transmitting member.
An image display apparatus comprising:
- a plurality of image display elements corresponding to a plurality of color light components;
- a color splitting prism configured to split light from a light source into a plurality of illumination light components that illuminate the plurality of image display elements;
- a plurality of polarization separating elements each disposed on corresponding one of light paths on which the plurality of illumination light components from the light source to the plurality of image display elements;
- a plurality of light transmitting members fixed to a plurality of emission surfaces through which the plurality of illumination light components exits from the color splitting prism;
- and
- a supporting member configured to support a pair of a light transmitting member and a polarization separating element corresponding to each other out of the plurality of light transmitting members and the plurality of polarization separating elements,
- wherein
- surfaces of the color splitting prism to which the light transmitting members are disposed are larger than the surfaces of the light transmitting members disposed on the color splitting prism,
- and wherein
- the supporting member is disposed on a side surface of the light transmitting member.
