摘要:
An image display apparatus comprises a hologram screen 2 formed by bonding a hologram element 20 to light-transmissible films 21 and an illumination device 11 for irradiating image light 10 onto the hologram screen and reproducing an image on the hologram screen 2. The light-transmissible film 21 positioned on the irradiation side of the image light 10 relative to the hologram element 20 has an angle deviation of not greater than 45 degrees between a direction of the light-transmissible film 21 that gives the highest thermal shrinkage ratio and an axial direction in the hologram screen 2. Therefore, the image display apparatus can provide high-quality images without the superposition of an interference pattern on the images on the hologram screen.
