To provide an antireflection film capable of suppressing variations in the appearance of reflected light depending on positions of the film caused by bending of the film, and a display device for a vehicle, which has a curved display screen capable of suppressing variations in the appearance of reflected light.SOLUTION: An antireflection film 20 is stuck onto a display screen 11 and has a particle-packed layer 22 packed with multilayer particles 221. The multilayer particle 221 has a particle configuration with layers of thin films having different refractive indices. While orientations of the individual multilayer particles 221 on the film surface are random, the multilayer particles 221 reflecting external light to a viewing direction are present in a certain proportion since the multilayer particles 221 are present in a great number. Reflected light from the multilayer particles 221 and reflected light by the film surface interfere with each other and function to compensate. Since the multilayer particles 221 are entirely distributed in the film, these particles macroscopically present a uniform appearance of reflected light over the entire film.SELECTED DRAWING: Figure 11
【課題】フィルムが湾曲されることによる場所ごとの反射光の見え方のばらつきを抑制可能な反射防止フィルム、及び、反射光の見え方のばらつきを抑制可能な湾曲した表示面を有する車両用表示装置を提供する。【解決手段】反射防止フィルム20は表示面11上に貼り付けられるフィルムであって、多層粒子221が充填されている粒子充填層22を有する。多層粒子221は、屈折率が異なる薄膜を積層した粒子状の構成である。個々の多層粒子221がフィルム表面になす姿勢はランダムであるが、多層粒子221は多数存在するため、外部光を視認方向に向けて反射する多層粒子221も一定の割合で存在する。多層粒子221が射出する反射光とフィルム表面での反射光とは干渉し、打ち消し合うように作用する。多層粒子221は、フィルム全体に分布しているため、巨視的には、フィルム全体において均一な反射光の見え方を提供する。【選択図】図11
