Abstract

A light transmissive panel for a vehicle includes base and a decorative layer. The base is disposed at a side of the light transmissive panel at which a design surface is provided. The base is transmissive to visible light. The decorative layer is stacked on a surface of the base body on a side opposite to the design surface. The light transmissive panel includes multiple apertures formed through the decorative layer in a thickness direction. Each aperture has a bottom surface formed by the base. The bottom surface has irregularities. The apertures are filled with filling portions, which are transmissive to visible light. The base and the filling portions are each formed of a plastic material with which the difference in refractive index between the base and the filling portions is less than the difference in refractive index between the base and air.

First claim

What is claimed is:

1 . A light transmissive panel for a vehicle configured to be disposed outward of a light source and to form a part of an outer shell of the vehicle, the light transmissive panel comprising:
a base disposed at a side of the light transmissive panel at which a design surface is provided, the base being transmissive to visible light; and a decorative layer stacked on a surface of the base on a side opposite to the design surface, wherein the light transmissive panel includes multiple apertures formed through the decorative layer in a thickness direction, each aperture having a bottom surface formed by the base, the bottom surfaces each have irregularities, the apertures are filled with filling portions that are transmissive to visible light, and the base and the filling portions are each formed of a plastic material with which a difference in refractive index between the base and the filling portions is less than a difference in refractive index between the base and air.

2 . The light transmissive panel for the vehicle according to claim 1 , wherein the base and the filling portions are each formed of plastic materials with which the difference in refractive index between the base and the filling portions is 0.2 or less.

3 . The light transmissive panel for the vehicle according to claim 1 , wherein the filling portions contain a colorant.

4 . The light transmissive panel for the vehicle according to claim 1 , wherein the decorative layer includes:
a colored layer containing a colorant; and a concealing layer provided at a side of the colored layer opposite to the base in the thickness direction, the concealing layer containing a colorant having a higher hiding power than that of the colorant contained in the colored layer.

5 . The light transmissive panel for the vehicle according to claim 1 , wherein the base includes:
a base body; and a protective layer stacked on a surface of the base body on a side opposite to the design surface, the protective layer containing an additive that reflects laser beams.
