Abstract
A head-up display device includes: a light source that emits light source light; a first light polarizer that takes out a linearly polarized light from the light source light; a liquid crystal layer, in which a display pixel that displays a picture and a non-displaying pixel which does not display a picture are able to be switched from each other, a polarization direction of the display pixel and a polarization direction of the non-displaying pixel being different from each other; and a second light polarizer. A part of the light source light corresponding to the display pixel passes through the second light polarizer by prohibiting a light of an interception axis intersecting a transmission axis while a light of the transmission axis is made to pass through.
