<P>PROBLEM TO BE SOLVED: To provide an image display device in which a high resolution and high quality are achieved by improving a high speed scanning part. Ž<P>SOLUTION: The image display device includes: a light source which emits light according to an image signal; a high-speed scanning part which scans light relatively in a first scanning direction at a high speed; a low-speed scanning part which scans light relatively in a second scanning direction intersecting substantially at a right angle with the first scanning direction at a low speed; and a control part which two-dimensionally scans the light emitted from the light source part by driving the high-speed drive part and the low speed drive part. The image display device includes: an optical path splitting part which splits the light of a first scanning region and the light of a second scanning region into a first optical path and a second optical path which have optical axes different from each other wherein the first and the second scanning regions substantially divide the scanning region of the high speed scanning part into two regions; and an optical path synthesizing part which superimposes the first scanning region and the second scanning region to form a synthesized scanning region by merging the light of the first scanning region and the light of the second scanning region which are split into the first optical path and the second optical path by the optical path splitting part to an optical path having an identical optical axis.
