PROBLEM TO BE SOLVED: To provide a glass article which has an excellent performance for preventing the diffusion of metal ions and does not have the problem of coloration caused by a metal colloid, and to provide a glass substrate using the glass article and used for a high quality display. SOLUTION: This glass article characterized by forming a metal ion diffusion- preventing film 2 consists mainly of indium oxide and/or tin oxide on the surface of an alkali-containing glass substrate 1. The glass substrate for the display, produced by forming an alkali ion diffusion-preventing film 5, a metal ion diffusion-preventing film 2 consisting mainly of indium oxide and/or tin oxide, an insulating film 3 and an electrode film 4 in this order on the surface of an alkali containing glass substrate 1, is characterized in that the surface resistance of the insulating film 3 is 1.0×106 to 1.0×1016Ω/(square) at 550 deg.C also after a thermal treatment for 1 hr. |
