Abstract: A touch sensor member includes a base material and a sensor circuit wiring formed on the base material, the base material includes a glass film having a thickness of 300 ?m or less, and the sensor circuit wiring includes a metal wire having a width of 25 ?m or less.

Abstract: Devised is a substrate material that allows an OLED element to have enhanced light extraction efficiency without forming a light extracting layer formed of a sintered compact, and exhibits excellent productivity. A crystallizable glass substrate (1) is used as the substrate material and applied to an OLED illumination device.

Abstract: Provided is crystallized glass, comprising, as a glass composition in terms of mass %, 55 to 73% of SiO2, 17 to 25% of Al2O3, 2 to 5% of Li2O, 2.5 to 5.5% of TiO2, 0 to 2.3% of ZrO2, 0.2 to 0.9% of SnO2, and 0.005 to 0.09% of V2O5, wherein the crystallized glass is substantially free of As2O3 and Sb2O3.

Abstract: To provide crystallizable glass that is less likely to be devitrified even when formed into shape by a float process, causes no breakage during a forming step and a crystallization step and is capable of precipitating LAS-based crystals as main crystals by subjecting the glass to heat treatment after being formed into shape, and crystallized glass obtained by crystallizing the crystallizable glass. The crystallizable glass of the present invention is characterized by substantially containing neither As2O3 nor Sb2O3 and having a composition of, in percent by mass, 55.0 to 73.0% SiO2, 17.0 to 27.0% Al2O3, 2.0 to 5.0% Li2O, 0 to 1.5% MgO, 0 to 1.5% ZnO, 0 to 1.0% Na2O, 0 to 1.0% K2O, 0 to 3.8% TiO2, 0 to 2.5% ZrO2, 0 to 0.6% SnO2, and 2.3 to 3.8% TiO2+ZrO2.

Abstract: A crystallized glass comprises, in term of mass %, 55 to 73% of SiO2, 17 to 25% of Al2O3, 2 to 5% of Li2O, 4 to 5.5% of TiO2, 0.05 to less than 0.2% of SnO2, and 0.02 to 0.1% of V2O5. The crystallized glass has a ratio V2O5/(SnO2+V2O5) of 0.2 to 0.4 and is substantially free of As2O3 and Sb2O3.
