摘要： According to an embodiment, an image display device includes an optical element, a voltage controller, and a display. Regarding the optical element, the refractive-index distribution changes according to the voltage applied thereto. The voltage controller controls, in a first mode, the voltage applied to the optical element in such a way that a first-type refractive-index distribution is achieved which acts as a first-type Fresnel lens; and controls, in a second mode that is different than the first mode, the voltage applied to the optical element in such a way that a second-type refractive-index distribution is achieved which acts as a second-type Fresnel lens having a greater number of steps than the first-type Fresnel lens. The display is disposed on the back side of the optical element and displays images.

摘要： According to an embodiment, a stereoscopic image display device includes a display, an optical element, a detector, a calculator, a deriver, and an applier. The display has a display surface including pixels arranged thereon. The optical element has a refractive-index distribution that changes according to an applied voltage. The detector detects a viewpoint position representing a position of a viewer. The calculator calculates a gravity point of the viewpoint positions when a plurality of viewpoint positions are detected. The deriver derives a drive mode according to the gravity point, where the drive mode is indicative of a voltage to be applied to the optical element. The applier applies a voltage to the optical element according to the drive mode such that a visible area within which a display object displayed on the display is stereoscopically viewable is set at the gravity position.
