Patent ID: 8422149

Claim:
A light modulation device that modulates an incident luminous flux according to image information to form an image, comprising: a light modulation section that is disposed in each of pixels constituting the image, wherein the light modulation section includes a condensing lens that concentrates the incident luminous flux, a shutter that is configured to be movable to a first position in which the shutter allows the luminous flux concentrated by the condensing lens to pass, or a second position in which the shutter blocks the luminous flux concentrated by the condensing lens, and a driver that moves the shutter to the first position or the second position; the shutter has an opening and is configured to be rotatable about a rotation axis along an opening direction of the opening, and the driver applies force to a peripheral edge of the shutter to rotate the shutter, thereby moving the shutter to the first position in which the shutter allows the luminous flux to pass through the opening, or the second position in which the shutter blocks the luminous flux at a portion excluding the opening.
