Head-mounted display apparatus

A head-mounted display apparatus, comprising:

• an image generating module configured to emit imaging light along a first optical axis;
• a first deflecting element including a first deflecting portion and a second deflecting portion, the first deflecting portion configured to deflect, along a second optical axis intersecting the first optical axis, the imaging light emitted from the image generating module, the second deflecting portion configured to deflect, along a third optical axis intersecting the second optical axis, the imaging light deflected by the first deflecting portion;
• a first diffraction element configured to diffract the imaging light deflected by the second deflecting portion;
• and
• a second diffraction element configured to diffract the imaging light diffracted by the first diffraction element to form an exit pupil, wherein
• the image generating module includes a plurality of image generating panels for emitting different colors of emission light and a color synthesizing element configured to synthesize the emission light emitted from the plurality of image generating panels,
• the color synthesizing element includes a first synthesis film and a second synthesis film, the first synthesis film and the second synthesis film intersecting each other,
• each of the plurality of image generating panels is disposed to face the color synthesizing element, and a longitudinal direction of an image generating region of the image generating panel is parallel to a line of intersection of the first synthesis film and the second synthesis film, and
• a distance along the first optical axis between the image generating module and the first deflecting portion is longer than a distance along the third optical axis between the first diffraction element and the second deflecting portion.
