A display device that includes: a glass substrate comprising a refractive index (nsubstrate); a display device structure coupled to the substrate to collectively define a viewing area; and a black mask structure surrounding the display device structure that is coupled to the substrate and comprises a black ink layer and at least one glossy layer between the black ink layer and the glass substrate. 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 CIE colorimetry system such that 5<L*<17 for the specular component included (SCI), and (c) a brightness in the CIE colorimetry system such that 0<L*<3 for the specular component excluded (SCE). Further, the at least one glossy layer comprises a refractive index (nglossy) such that |nglossy−nsubstrate|>0.1.
