To provide an optical scanner which surely detects a scan light and suppresses an unwanted light.SOLUTION: A display device 100 includes: an optical deflector 13 for deflecting light emitted from a light source device 11 and conducting a scan two dimensionally (main-scan direction and sub-scan direction); and a light-receiving element 61 detecting a scan light when the optical deflector 13 scans a detection region in a scan region G to be scanned dimensionally. In the scan region G, a detection image region G3 is formed by a scan light to include an end part of the detection region, and the size of the detection image region G3 is changed in the main-scan direction or the sub-scan direction.SELECTED DRAWING: Figure 17
【課題】走査光を確実に検知し、不要光を抑制した光走査装置を提供する。【解決手段】光源装置11から照射された光を偏向して主走査方向および副走査方向の二次元走査する光偏向装置13と、二次元走査される領域である走査領域Gに含まれる検知領域を、光偏向装置13が走査するときの走査光を検知する受光素子61と、を有し、走査領域Gには走査光によって、検知領域の端部を含むように検知用画像領域G3が形成され、検知用画像領域G3の主走査方向または副走査方向のサイズを変化させる表示装置100である。【選択図】図17
