PROBLEM TO BE SOLVED: To provide an image display apparatus that achieves both of a larger screen and a reduced size without degrading brightness near an edge of an image.SOLUTION: The image display apparatus includes: a light dispersing member 210 configured to disperse a luminous flux of an image light exiting from a light source based on predetermined image information; a scanning optical system configured to scan the image light exiting from the light source in a main scanning direction and a sub scanning direction by light-scanning means 208 to form an intermediate image G' on the light dispersing member; and a projection optical system configured to project the image light from the light dispersing member onto a light-transmitting projection target member to be reflected on the projection target member, and to guide the reflected light to within a specific viewpoint range. The scanning optical system is configured in such a manner that a center ray L1, L2 in an end luminous flux after exiting from the light dispersing member, corresponding to an end position in the main scanning direction of the intermediate image G', directs from the center point of specific viewpoint range S in the main scanning direction to a center region within a predetermined distance.

    【課題】画像端部付近の輝度を落とすことなく、大画面化と小型化の両立を実現した図ることができる画像表示装置を提供する。【解決手段】所定の画像情報に基づいて光源から出射した画像光の光束を発散させる光発散部材210と、前記光源から出射される画像光を光走査手段208により主走査方向と副走査方向とに走査して前記光発散部材上に中間像G’を形成する走査光学系と、光透過性を有する被投射部材に向けて前記光発散部材からの画像光を投射し、該被投射部材で反射させて特定の視点範囲内に導く投射光学系とを有する画像表示装置において、前記走査光学系は、前記中間像G’の主走査方向端部位置に対応する端部光束における前記光発散部材の出射後の中心光線L1,L2が、主走査方向における前記視点範囲Sの中心点から所定距離内の中心領域に向かうように、構成されている。【選択図】図1
