PROBLEM TO BE SOLVED: To enable at least one of reduction in necessary main scanning frequency, increase in necessary subscanning frequency and increase in scanning lines by improving scanning trajectory in a technology by which a picture is displayed by the two-dimensional scanning of a luminous flux. SOLUTION: In the optical scanning type display 10, a brightness signal is generated on the basis of a video signal so that one frame of the picture is divided into three or more fields and scanned and displayed by an optical scanning unit 20. Further, during an effective scanning period in the entire period of each reciprocating scanning, the generated brightness signal is outputted to a light source part 34 so that effective scanning lines formed by actual luminous flux emission from the light source part 34 do not overlap one another in the three or more fields in a same frame.
