Abstract:
An image display apparatus comprising:a hologram screen for receiving image light irradiated from an illumination device to thereby reproduce an image on said hologram screen, wherein: said hologram screen is formed by bonding a hologram element to light-transmissible films; said image light includes R, G, and B components, and wherein the R and the B components include P polarized light, and wherein the G component includes a combination of P polarized light and S polarized light; and one of said light-transmissible films positioned on an irradiation side of said image light relative to said hologram screen has an angle of deviation of not greater than 45 degrees, said angle of deviation being between a direction of said one of said light-transmissible films having a highest thermal shrinkage ratio and an axial direction of said hologram screen.
