PROBLEM TO BE SOLVED: To provide an image display device that can improve efficiency for light utilization.SOLUTION: An image display device 1000 is an image display device that scans a microlens array (scanned surface element 8) including a plurality of microlenses with laser light modulated on the basis of image information to form an image, makes the laser light transmitted through the microlens array incident on a transmission and reflection member (reflection surface element 10), and enables an observer to visually recognize a virtual image of the image from a predetermined observation position on a light path of the laser light reflected on the transmission and reflection member. The curvature of the plurality of microlenses is set on the basis of the length of the light path of the laser light between the microlenses and the observation position. In this case, efficiency for light utilization can be improved.SELECTED DRAWING: Figure 1

    【課題】光利用効率を向上させることができる画像表示装置を提供する。【解決手段】 画像表示装置画1000は、画像情報に基づいて変調されたレーザ光により複数のマイクロレンズを含むマイクロレンズアレイ(被走査面素子8)を走査して画像を形成し、前記マイクロレンズアレイを透過したレーザ光を透過反射部材(反射面素子10)に入射させて、該透過反射部材で反射されたレーザ光の光路上の所定の観察位置から前記画像の虚像を視認可能にする画像表示装置であり、前記複数のマイクロレンズそれぞれの曲率は、該マイクロレンズと前記観察位置との間のレーザ光の光路長に基づいて設定されている。この場合、光利用効率を向上させることができる。【選択図】図1
