Optical module and head-mounted display apparatus

An optical module comprising:

• a first image display panel including:
• a first display part having a rectangular shape;
• and
• a first coupling part;
• a second image display panel including:
• a second display part having a rectangular shape;
• and
• a second coupling part;
• a third image display panel including:
• a third display part having a rectangular shape;
• and
• a third coupling part;
• and
• a cross dichroic prism including a two of photosynthesis surfaces, and configured to synthesize first image light emitted from the first image display panel, second image light emitted from the second image display panel, and third image light emitted from the third image display panel,
• wherein the cross dichroic prism has a cross axis at which the two of photosynthesis surfaces cross each other, and
• the first image display panel, the second image display panel, and the third image display panel are respectively bonded to different surfaces of the cross dichroic prism,
• the first image display panel is arranged so that a long side of the first display part extends along the cross axis and the first coupling part do not face the cross dichroic prism,
• the second image display panel is arranged so that a long side of the second display part extends along the cross axis and the second coupling part do not face the cross dichroic prism, and
• the third image display panel is arranged so that a long side of the third display part extends along the cross axis and the third coupling part do not face the cross dichroic prism.
