The invention provides a light source unit and an image display device which are small in size and capable of displaying high-quality images. A light source unit is provided with: a display device having a pixel column including a plurality of pixels arranged in a first direction; and an image forming optical system including an output element and a movable optical system on which light emitted from the display device is incident, which is movable about an axis parallel to the first direction, and which emits light at an angle corresponding to a movable state, and which forms an image with light emitted from the output element. Light is incident on the output element via the movable optical system. The imaging optical system has great telecentricity on the image side, and light emitted from the display device has substantially Lambertian light distribution.
