PROBLEM TO BE SOLVED: To obtain a reflection-reduced glass bearing such functionally gradient characteristics as to gradually change the angle dependency of its reflection preventive characteristics from the above toward the below so as to improve the view-securing performance of the relevant driver. SOLUTION: This refection-reduced glass is obtained by providing at least one side of a transparent glass substrate with, as the 1st layer from the glass surface, a thin film layer 1.75-1.95 in refractive index (n1 ) with its thickness changed gradually within the range between 90 and 110nm followed by laminating the 1st layer with the 2nd thin film layer 2.1-2.3 in refractive index (n2 ) and 150-170nm in thickness and then laminating the 2nd layer with the 3rd thin film layer 1.4-1.5 in refractive index (n3 ) and 110-130nm in thickness. |
