Abstract:
1. An image display apparatus comprising: a first optical modulation device and a second optical modulation device configured to emit an image light formed as linearly polarized lights whose polarization directions are perpendicular to each other, the first optical modulation device and the second optical modulation device include; first pixels forming a first image light and second pixels forming a second image light arranged in at least one direction in each of the first optical modulation device and the second optical modulation device; and retardation layers disposed on the light emission side of the first pixels or second pixels, the retardation layers configured to convert one linearly polarized light of the linearly polarized lights into the other linearly polarized light, wherein an arrangement of the first pixels and the second pixels in the first optical modulation device is set so as to be the reverse of an arrangement of the first pixels and the second pixels in the second optical modulation device, and arrangements of the retardation layers in the first optical modulation device and the second optical modulation device are set so as to be the same as each other, wherein a light emitted from the second pixels on the first optical modulation device side and a light emitted from the first pixels on the second optical modulation device side is converted in polarization direction by the retardation layers and emitted.
