A scanning display includes plural light sources (101a-d), and a scanner (102) for two-dimensionally scanning a scanning area (103) in a scanning surface from lights from the plural light sources (101a-d), wherein the scanner (102) scans plural partial scanning areas (103a-d) that are arranged in a first direction (104) within a range corresponding to the scanning area (103), by using mutually different lights from the plural light sources (101a-d), the scanner (102) scanning each partial scanning area (103a-d) at a first speed in the first direction (104) and at a second speed higher than the first speed in a second direction (106) different from the first direction (104), and wherein FR ‰§ (É × Z) / (± × Fov) is met, where FR is a scanning frequency (Hz) of the light in the first direction (104) of the partial scanning area, É is an oculomotor angular speed (°/sec) in a saccade, Z is the number of partial scanning areas arranged in the first direction (104) in the scanning area (103), ± is a constant relating to an effective scanning period in one scanning period in the first direction (104), and Fov is an entire view angle (°) in the first direction.
