    • A glass substrate having a transparent conductive film of SnO2 is disclosed, in which the transparent conductive film is prevented from developing hair cracks even when it has a thickness of 5,000 Å or larger. The glass substrate comprises an alkali-containing base glass plate 10 having a smooth surface and, formed thereon in this order, an undercoat 12 for imparting roughness which has a thickness of 150 Å or larger and is made of a crystalline metal oxide, a continuous alkali barrier film 14 made of SiO2 and having such a small thickness as to reflect the surface roughness of the undercoat, and a transparent conductive film 16 made of SnO2 doped with one or more appropriate impurities and having a thickness of 5,000 Å or larger. The transparent conductive film has an adhesion strength of 37 mN or higher as measured in accordance with “Adhesion Test for Thin Film Deposited on Glass Substrate ” as provided for in JIS R3255-1997.
    • 公开了一种具有SnO 2透明导电膜的玻璃基板,其中,即使具有5000以上的厚度,也可以防止透明导电膜发生毛发裂纹。 玻璃基板包括具有光滑表面的含碱基玻璃板10,并且在其上依次形成用于赋予厚度为或大于150埃的粗糙度的底涂层12,其由结晶金属氧化物制成,连续的 由SiO 2制成并具有如此小的厚度以反映底涂层的表面粗糙度的碱性阻挡膜14,以及由掺杂有一种或多种合适杂质并且具有5000或更大的厚度的SnO 2制成的透明导电膜16。 该透明导电膜的粘合强度为按照JIS R3255-1997中规定的“玻璃基板上的薄膜的粘合试验”所测得的37mN以上。
