<p>PROBLEM TO BE SOLVED: To obtain a low reflection glass for substrate of a touch panel on which a multilayered film consisting of a transparent oxide with a specified refractive index and film thickness is formed, in which light reflection is reduced, a feeling of glare is eliminated and transparency is increased. SOLUTION: The low reflection glass for substrate of a touch panel is obtained by forming a transparent oxide film, whose refractive index n1 is 2.05 to 2.25, film thickness d1 is 20 to 50 nm as a first layer 9 from a transparent glass substrate 3, forming a transparent oxide film, whose refractive index n2 is 1.43 to 1.47, film thickness d2 is 60 to 90 nm as a second layer 10 on the first layer 9 next, furthermore, forming a transparent conductive film, whose film thickness d3 is within the range about 10 to 25 nm on an upper surface of a transparent glass substrate 3. Besides, a transparent oxide film whose refractive index n1' is 1.70 to 1.90, film thickness d1' is 60 to 90 nm is formed as a 1' th layer 9' from the substrate, then a transparent oxide film, whose refractive index n2' is 1.43 to 1.47, film thickness d2' is 80 to 110 nm is formed as a 2' th layer 10' on the 1' th layer 9', on the rear surface of the transparent glass substrate 3 and the visible beam reflection rate is defined as <=2.0%. In addition, the combination of a film thickness d1 of 80 to 110 nm and a film thickness d2 of 15 to 50 nm.</p> |
