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 2):
The head-up display device according to  claim 1 , wherein\n the optical condenser has a lens face which is a convex free curved surface and is formed asymmetrically in the vertical direction, and is formed such that an optical length from the light source to the curved surface is shortened by reducing a curvature of the lens face corresponding to a position for decreasing illuminance of the light emission face in order to decrease the illuminance of the light emission face in a side optically conjugated with an upper side in the vertical direction of the visible area.
