1. A front plate for a lighting device, comprising:
- a translucent substrate having a first surface;
a high refractive index layer formed on the first surface of the translucent substrate and having a refractive index higher than a refractive index of the translucent substrate; and
an electrically conductive light reflection layer formed on a surface of the high refractive index layer on an opposite side of the translucent substrate,wherein the electrically conductive light reflection layer is formed on a portion corresponding to a non-luminous region around a luminous region on the surface of the high refractive index layer.

Abstract
A front plate for a lighting device includes a translucent substrate having a first surface, a high refractive index layer formed on the first surface of the translucent substrate and having a refractive index higher than a refractive index of the translucent substrate, and an electrically conductive light reflection layer formed on a surface of the high refractive index layer on an opposite side of the translucent substrate. The electrically conductive light reflection layer is formed on a portion corresponding to a non-luminous region around a luminous region on the surface of the high refractive index layer.
