Abstract:
A head-up display device has a backlight unit configured to illuminate a liquid crystal panel from a back side. The backlight unit has an optical condenser configured to condense the light emitted from a light source toward the liquid crystal panel, and a microlens array arranged in an optical path between the optical condenser and the liquid crystal panel to diffuse the light condensed by the optical condenser. The microlens array has a light emission face arranged in a position optically conjugated with an eyebox to emit the light incident from the optical condenser.

Claim (Index 9):
A head-up display device comprising:\n a display that emits a display light corresponding to a display image, the head-up display device allowing a driver to visually recognize a virtual image displayed in front of a display member depending on the display image in a driver's visible area in a vehicle by projecting the display image displayed on the display onto the display member through an optical system of the vehicle, wherein the display has a transmission type liquid-crystal display element, and a backlight unit that illuminates the liquid-crystal display element from a back side thereof, the backlight unit has a single light source, an optical condenser that condenses light emitted from the light source toward the liquid-crystal display element, and a diffuser arranged in an optical path between the optical condenser and the liquid-crystal display element to diffuse the light condensed by the optical condenser, and the diffuser has a light emission face arranged in a position optically conjugated with the visible area to emit the light incident from the optical condenser, and is arranged with an inclination against an optical axis direction of the light emission face in order to provide a constant luminance distribution in a vertical direction of the visible area.
