A vehicular number plate including luminous characters of the type comprising a number plate having a plurality of character portions punched therefrom to which a plate molded of a transparent or translucent synthetic resin is adhesively secured and illuminating bulbs for illuminating the character portions, wherein a light scattering plate having a number of quadrangular pyramid-shaped light scattering projections formed thereon is interposed between the number plate and the illuminating bulbs in an area corresponding to positions where the illuminating bulbs are disposed, Each of the quadrangular pyramid-shaped projections has an apex angle which is determined in the range of 90 .degree. to 160.degree. , The illuminating bulbs may be replaced with a single fluorescent lamp, In this case, the light scattering plate includes a receiving portion in which the fluorescent lamp is received and a light scattering portion extending from the receiving portion while having a gradually reduced thickness. The light scattering plate is interposed between the number plate and the fluorescent lamp. To scatter the incoming light, the light scattering portion is formed with a number of light scattering grooves extending in parallel with the fluorescent lamp.
