An image display apparatus mounted in a head up display apparatus includes: an image display element that outputs display light; a diffusing member that receives the display light at a light receiving surface and outputs the display light as diffused light from a light output surface; and a light deflecting means that deflects the display light output from the image display element, provided between the image display element and the diffusing member. An image display surface of the image display element and the light output surface of the diffusing member are parallel, and the image display element, the diffusing member, and the light deflecting means are arranged in a state such that a line normal to the light output surface of the diffusing member is inclined with respect to the optical axis of the display light after being deflected by the light deflecting means.
