Abstract
A reflective structure with transparent and semi-transparent transmission regions and includes a first transparent layer with a textured area, a reflective layer disposed below the first transparent layer and having a portion that is substantially conformal with at least a first portion of the textured area, and a second transparent layer disposed below the reflective layer and having a portion with a refractive index that is substantially equal to a refractive index of the first transparent layer. The transparent transmission region is configured to transmit a portion of light without substantial deviation, and the semi-transparent transmission region is configured to transmit another portion of the light from the first transparent layer with substantial deviation.
