To provide an optical element which is advantageous in making brightness of a virtual image uniform, and a method of manufacturing the same.SOLUTION: An optical element provided herein comprises a light-transmissive substrate and a plurality of reflective surfaces for reflecting incident light. The plurality of reflective surfaces are inclined relative to a surface of the substrate at given angles that depend on a distance from a reference point. Area of each of the plurality of reflective surfaces is substantially the same as those of the others when viewed from a normal direction side.SELECTED DRAWING: Figure 6
【課題】虚像の輝度を均一にすることに関して、優位な、光学素子及び光学素子の製造方法を提供する。【解決手段】光学素子は、光透過性の基板と、入射する光を反射する複数の反射面とを備える。複数の反射面は、基板の基板面に対して基準点からの距離に応じた所定角度で傾斜する。複数の反射面のそれぞれの法線方向側から観た複数の反射面のそれぞれの面積は、略等しい。【選択図】図6
