The present invention provides a high transmission glass with an ITO film which is excellent in a higher transmittance and reduced reflection, produced by fewer steps at lower cost, and used as an optical switch for optical communication utilizing infrared ray. The high transmission ITO film-coated glass is used for a liquid crystal device utilizing infrared ray having a wavelength region from 1530 nm to 1570 nm as incident light. The high transmission ITO film-coated glass 10 is configured to be arranged to sandwich a liquid crystal layer, the high transmission ITO film-coated glass has an ITO film 2 formed on an inside face of the glass substrate 1 to face the liquid crystal layer when arranged with the liquid crystal layer, and the high transmission ITO film-coated glass has a SiOx film 11 (1≤x2) formed between the ITO film 2 and the glass substrate 1. 展开▼
