PROBLEM TO BE SOLVED: To provide an image display device that can suppress a reduction in luminance, a virtual image display device, and a movable body.SOLUTION: An image display device 110 comprises: a light source device 20 that emits light; a liquid crystal panel 30; an optical system 40; and a polarizing element 50. The liquid crystal panel 30 transmits therethrough, of light from the light source device 20, a component in a first direction of a display surface 31 to form an image on the display surface 31. The optical system 40 is arranged between the light source device 20 and liquid crystal panel 30, and diverges light from the light source device 20 in a third direction parallel to the display surface 31 and intersecting with the first direction. The polarizing element 50 is arranged between the optical system 40 and liquid crystal panel 30, and rotates the polarization direction of light from the optical system 40 such that light made incident on the liquid crystal panel 30 has, as its component in the first direction, a component in the third direction of the light from the optical system 40.SELECTED DRAWING: Figure 4

    【課題】本開示の課題は、輝度の低下を低減できる画像表示装置、虚像表示装置、及び移動体を提供することである。【解決手段】画像表示装置110は、光を放射する光源装置20と、液晶パネル30と、光学系40と、偏光素子50と、を備える。液晶パネル30は、光源装置20からの光のうち表示面31の第1方向の成分を透過させて表示面31に画像を形成する。光学系40は、光源装置20と液晶パネル30との間にあり、表示面31に平行し第1方向と交差する第3方向において光源装置20からの光を発散させる。偏光素子50は、光学系40と液晶パネル30との間にあり、液晶パネル30に入射する光が光学系40からの光の第3方向の成分をその第1方向の成分として有するように光学系40からの光の偏光方向を回転させる。【選択図】図4
