PROBLEM TO BE SOLVED: To provide an image display furnished with a telecentric optical system in which aberration generated by the difference in optical paths of a plurality of light beams emitted from respective light sources is minimized and light condensing characteristic is improved. SOLUTION: The image display includes the telecentric optical system provided with: a plurality of light sources 2 (2a, 2b, 2c and others); a condensing lens 5 which condenses the light beams emitted from the plurality of light sources 2; and a light receiving plate 6 having a light receiving face which receives light beams condensed with the condensing lens 5, wherein each of the plurality of light sources 2 (2a, 2b, 2c and others) is so arranged that the aberration of the respective light sources 2 is minimized and the distances on the lines vertically drawn from the respective light sources 2 to the plane which passes through the center of the condensing lens 5 and is perpendicular to an optical axis are different from each other.
