1. A display device, comprising:
a glass substrate comprising a refractive index (nsubstrate);
a display device structure that comprises a light source and a plurality of films, the display device structure coupled to the substrate to collectively define a viewing area; and
a black mask structure surrounding the display device structure, the black mask structure coupled to the substrate,
wherein the black mask structure comprises a black ink layer and at least one glossy layer between the black ink layer and the glass substrate,
wherein the viewing area is characterized by (a) a reflectance from 0.5% to 2.5% as measured at 8 degrees from normal in the visible spectrum, (b) a brightness in the (L*, a*, b*) CIE colorimetry system such that 5<L*<17 for the specular component included (SCI), and (c) a brightness in the (L*, a*, b*) CIE colorimetry system such that 0<L*<3 for the specular component excluded (SCE), and
further wherein the at least one glossy layer comprises a refractive index (nglossy) such that nglossy−nsubstrate|>0.1.
