An image display apparatus , comprising: an image forming element that forms an intermediate image on an image formation surface of a surface element ; and a virtual image optical system that forms a virtual image based on the intermediate image, wherein the image display apparatus projects the virtual image on a front windshield of a mobile body to allow a user to visually recognize the virtual image, the virtual image optical system includes a magnifying concave mirror that enlarges and projects the intermediate image toward the front windshield , when a right-left direction of a field of view of the user is defined as an X-axis direction, a vertical direction of the field of view of the user is defined a Y-axis direction, and a direction orthogonal to both the X-axis direction and the Y-axis direction is defined as a Z-axis direction, ends of the magnifying concave mirror and ends of the surface element face each other in a X-Z plane, and the magnifying concave mirror is disposed to be inclined relative to the X-axis direction such that a length between one end of the magnifying concave mirror in the X-axis direction and one end of the surface element in the X-axis direction is longer than a length between the other end of the magnifying concave mirror in the X-axis direction and the other end of the surface element in the X-axis direction in the X-Z plane, characterized in that the front windshield is curved in the X-Z plane, and an inclination direction of the magnifying concave mirror is the same as an inclination direction of the front windshield , and the magnifying concave mirror is disposed along a curved surface of the front windshield . an image forming element that forms an intermediate image on an image formation surface of a surface element ; and a virtual image optical system that forms a virtual image based on the intermediate image, wherein the image display apparatus projects the virtual image on a front windshield of a mobile body to allow a user to visually recognize the virtual image, the virtual image optical system includes a magnifying concave mirror that enlarges and projects the intermediate image toward the front windshield , when a right-left direction of a field of view of the user is defined as an X-axis direction, a vertical direction of the field of view of the user is defined a Y-axis direction, and a direction orthogonal to both the X-axis direction and the Y-axis direction is defined as a Z-axis direction, ends of the magnifying concave mirror and ends of the surface element face each other in a X-Z plane, and the magnifying concave mirror is disposed to be inclined relative to the X-axis direction such that a length between one end of the magnifying concave mirror in the X-axis direction and one end of the surface element in the X-axis direction is longer than a length between the other end of the magnifying concave mirror in the X-axis direction and the other end of the surface element in the X-axis direction in the X-Z plane, characterized in that the front windshield is curved in the X-Z plane, and an inclination direction of the magnifying concave mirror is the same as an inclination direction of the front windshield , and the magnifying concave mirror is disposed along a curved surface of the front windshield . <EOS>
