The invention provides an information display device with high contrast and greatly improved light resistance to sunlight. In order to solve the above problem, an information display device for displaying video information on a projection surface using a virtual image, the information display device comprising: a video light generation unit for generating video light for displaying the video information inside a housing provided with an opening part in part; an image light processing unit that performs predetermined optical processing on the image light from the image light generating unit; and an image projection unit that projects the image light from the image light processing unit onto the projection surface through the opening of the housing so that an observer can recognize the image information as a virtual image in front of the projection surface. An optical element obtained by fixing a reflective polarizer to a transmissive substrate is provided on an optical path inside the housing as a means for selectively reflecting a P-polarized component of light in a visible light band.

    本发明提供一种高对比度且大幅提高了对于太阳光的耐光性的信息显示装置。为了解决上述问题,一种利用虚像在投影面上显示影像信息的信息显示装置,其中,在局部设有开口部的壳体的内部,包括:生成用于显示影像信息的影像光的影像光生成单元;对来自所述影像光生成单元的影像光实施规定的光学处理的影像光处理单元;和影像投影单元,其将来自所述影像光处理单元的影像光经由所述壳体的开口部投影到所述投影面上,使得观察者能够将影像信息在所述投影面的前方识别为虚像。在所述壳体的内部的光路上,作为有选择地使可见光波段的光的P偏振成分反射的单元,设置有通过将反射型偏振片固定在透射性的基板上而得到的光学元件。
