Claim 7:
8. The cover glass of claim 7, wherein the second coat layer is configured to provide anti-fingerprint visibility, and wherein ΔE*ab is four or less according to Equation 1 below:

ΔE*ab=√{right arrow over ((L*2−L*1)2+(a*2−a*1)2+(b*2−b*1)2)}  [Equation 1]

wherein L*1 is a brightness value before processed with the second coat layer, L*2 is a brightness value after processed with the second coat layer, a*1 is a color value before processed with the second coat layer, a*2 is a color value after processed with the second coat layer, b*1 is a chroma value before processed with the second coat layer, and b*2 is a chroma value after processed with the second coat layer.
