Abstract
A vehicle backlit panel includes a base substrate, an electroluminescent element and an outer substrate. The electroluminescent element is disposed on one side of the base substrate. The outer substrate overlies the electroluminescent element. The outer substrate includes a translucent substrate portion having areas of different thicknesses as measured in a direction of illumination through the outer substrate to form a three-dimensional graphic image with a three-dimensional appearance resulting from different translucency levels of the areas of different thicknesses.
