Zusammenfassung:	To provide an image display device that reduces deterioration of visibility due to specular reflection of a lens that occurs when an image is displayed through the lens.SOLUTION: An image display device includes a display unit 12 having a display surface for displaying an image, a rear image generation unit 21 that generates an image to be displayed on the display surface, a Fresnel convex lens 14T arranged at a predetermined distance from the display surface, specular reflection prevention means for making the rear surface 14Tb of the Fresnel convex lens 14T inclined such that the light incident from the user side viewing the image is not specularly reflected to the user side, and an image correction unit 22 that corrects image distortion due to the use of the specular reflection prevention means.SELECTED DRAWING: Figure 5 【課題】レンズを通して画像を表示する際に生じるレンズの正反射による視認性の悪化を低減する画像表示装置を提供する。【解決手段】画像表示装置は、画像を表示する表示面を有する表示部１２と、表示面に表示する画像を生成する後方画像生成部２１と、表示面と所定の距離を隔てて配置されているフレネル凸レンズ１４Ｔと、フレネル凸レンズ１４Ｔの裏面１４Ｔｂを、画像を見る利用者側から入射する光が利用者側に正反射しない傾斜とする正反射防止手段と、正反射防止手段を用いることによる画像の歪みを補正する画像補正部２２とを備えている。【選択図】図５
