  "textContent": "The head-up display device includes a light source; a condensing lens; a lens array diffusing light from the condensing lens; a liquid-crystal display unit emitting light from the lens array as display light; and a reflecting member reflecting the display light emitted from the liquid-crystal display unit and projecting the display light on a windshield. The lens array has, in an emitting surface, a plurality of lens surfaces projecting toward the liquid-crystal display unit and having an aspherical sectional shape, and, in the lens surface, the curvature radius of a part emitting display light to be projected on an upper part of the windshield is smaller than the curvature radius of a part emitting display light to be projected on a lower part of the windshield.",
