ABSTRACT:
A diffuser is provided that includes a glass substrate with a diffusing coating thereon. The diffusing coating may include one or more layers. In certain example embodiments, the diffusing coating comprises inorganic pigments therein for light diffusing purposes, and the inorganic pigments are sized so as to permit a diffuser having a combination of high visible transmission and good diffusion qualities to be realized. In certain example embodiments, the diffusing coating may be of or include a frit with the inorganic pigments therein.
