Abstract
An image display device that displays an image by modulating a light from a light source according to display image data, includes: a first light modulation element that modulates a light emitted from the light source; and a second light modulation element that is disposed on an optical path in series with the first light modulation element and modulates a light exiting from the first light modulation element, wherein the first light modulation element and the second light modulation element are disposed in such a manner that a bright-field direction of an optical image of the first light modulation element and a bright-field direction of the second light modulation element almost coincide with each other.
