The invention provides a light source unit and an image display device which are small in size and capable of displaying high-quality images. The light source unit includes: a display device capable of displaying an image; and an image forming optical system including an input element into which the light emitted from the display device is incident and an output element into which the light passing through the input element is incident, the light emitted from the output element forming a first image corresponding to the image. The imaging optical system has great telecentricity on the first image side. The light emitted from the display device has a substantially Lambert light distribution. The display device has a plurality of pixels configured to cancel two-dimensional distortion of an optical system including an imaging optical system.
