A vehicle display device comprising: a light source; a display device that emits, as display light, a display image projected on a projected member provided on a vehicle by light incident from the light source; a first lens arranged on an optical path between the light source and the display device, and polarizing the light incident from the light source; and a second lens arranged between the first lens and the display device on the optical path, and distributing the light polarized through the first lens toward the display device, wherein the first lens includes an incident surface onto which the light from the light source is incident; and an emitting surface that emits light toward the display device, the first lens is configured to refract light traveling toward the outside inward and cause the light to be polarized, and the emitting surface of the first lens is formed of one convex curved surface corresponding to the light source, the second lens includes: an incident surface onto which the light polarized through the first lens is incident; and an emitting surface which is formed in a convex shape to be curved toward the display device side and through which the light incident on and transmitting through the incident surface is emitted, and a plurality of curved microlens surfaces are formed on the emitting surface of the second lens so as to be arranged along the emitting surface of the second lens. a light source; a display device that emits, as display light, a display image projected on a projected member provided on a vehicle by light incident from the light source; a first lens arranged on an optical path between the light source and the display device, and polarizing the light incident from the light source; and a second lens arranged between the first lens and the display device on the optical path, and distributing the light polarized through the first lens toward the display device, wherein the first lens includes an incident surface onto which the light from the light source is incident; and an emitting surface that emits light toward the display device, the first lens is configured to refract light traveling toward the outside inward and cause the light to be polarized, and the emitting surface of the first lens is formed of one convex curved surface corresponding to the light source, the second lens includes: an incident surface onto which the light polarized through the first lens is incident; and an emitting surface which is formed in a convex shape to be curved toward the display device side and through which the light incident on and transmitting through the incident surface is emitted, and a plurality of curved microlens surfaces are formed on the emitting surface of the second lens so as to be arranged along the emitting surface of the second lens. an incident surface onto which the light polarized through the first lens is incident; and an emitting surface which is formed in a convex shape to be curved toward the display device side and through which the light incident on and transmitting through the incident surface is emitted, and a plurality of curved microlens surfaces are formed on the emitting surface of the second lens so as to be arranged along the emitting surface of the second lens.
