Abstract

PURPOSE:To prevent the secular change in the display quality of a liquid crystal cell by using chemically treated sapphire glass or glass coated with SiO2 at <=350 deg.C for an upper electrode substrate. CONSTITUTION:On the mutually facing surfaces of the substrates 1 and 2 of an electronic timepiece, an SiO2 film 21, transparent electrodes 22, and an orienting film 23 orienting liquid crystal adequately which is sandwiched between the substrates 1 and 2 are provided. As the substrate glass of a liquid crystal cell, the SiO2 film 21 is provided except when glass which contains little Na2O like sapphire glass is used. In this case, a method of sputtering by heating the material up to <=350 deg.C secures performance higher than that by a conventional impregnating means, a CVD method without causing deterioration.
