The lens includes: an incident surface where the light enters; and an emission surface for radiating the light to the front side. The incident surface includes: a first light diffusion part provided in a central side region where the light enters radiated in a predetermined range in the horizontal direction from the vertical reference line on a screen; and a second light diffusion part provided in the central side region and continued to the lower side of the first light diffusion part. The boundary between the first light diffusion part and the second light diffusion part is located in the first range in the vertical direction for allowing the light radiated on the cutoff line of the incident surface to enter, and the second light diffusion part has diffusion width larger than that of the first light diffusion part.SELECTED DRAWING: Figure 7
