Abstract
An image display deviceincludes a laser light source unit, a screenformed of at least two diffusion members, a vibration mechanismvibrating at least one diffusion member, and a scanning elementscanning laser light in a first direction (a y direction) on the screen and a second direction (an x direction) orthogonal to the first direction. A scanning speed of the scanning elementin the second direction is faster than a scanning speed in the first direction, and a diameter D of the laser light in the first direction on the screen is greater than an interval Yp in the first direction on the scanning trajectory in the second direction on the screen. Accordingly, it is possible to provide an image display device displaying an image having a low speckle with high luminance, without vibrating the diffusion member at a high speed.
