Abstract:
Provided is a small-sized information display device displaying video image information as a virtual image by use of an eyepiece optical system including a concave mirror having desired reflection characteristics in a specific polarization direction, where a liquid crystal display panel is used as a video image light source. The information display device has a liquid crystal display panel as a flat display forming video image information disposed therein, and includes a virtual image optical system including a member to be projected for displaying virtual images in front of a vehicle by making a video image displayed on the liquid crystal display panel reflect on the member to be projected. The virtual image optical system includes a concave mirror, and a reflective film of the concave mirror has desired reflection characteristics in a specific polarization direction, so that virtual images having uniform brightness and chromaticity can be obtained.

Claim (Index 1):
An information display device displaying video image information of a virtual image on a windshield of a vehicle, comprising:\n a liquid crystal display panel displaying the video image information; and a virtual image optical system displaying the virtual image in front of the vehicle by reflecting light emitted from the liquid crystal display panel on the windshield, wherein the virtual image optical system includes a concave mirror and a plurality of optical elements, wherein the concave mirror includes a reflection surface made of a metal film having a high and uniform spectral reflectance with respect to a visible light, on a front surface of a base material, and wherein the plurality of optical elements are disposed between the liquid crystal display panel and the concave mirror so as to separate a video image light flux to establish each virtual image of a plurality of virtual images such that the plurality of virtual images are respectively established at a plurality of positions corresponding to viewpoint positions of a driver from an upper portion to a lower portion of the windshield.
