Abstract
The light emitted from a warning display unit 16 is passed through a front glass 18 formed at the opening of a dash board 17 and a semi-permeable combiner 12 having a first polarizing plate 12b in this order so that it is guided to a driver'"'"'s view point I. A second polarizing plate having the same polarizing direction as that of the first polarizing plate 12b is formed on the surface of the front glass 18. In this configuration, the wash-out in the warning display unit, i.e. a light emitting source, arranged behind a combiner can be prevented and visual recognition of the light emitting source can be improved.
