Abstract
The invention relates to a reflectance-reducing glass pane which may be a laminated glass pane such as an automobile front windshield. The invention provides a reflectance-reducing glass pane including: a transparent glass substrate having first and second major surfaces opposed to each other; a first reflectance-reducing coating formed on the first major surface of the glass substrate; and a second reflectance-reducing coating formed on the second major surface of the glass substrate. The first coating has at least two metal-oxide layers which are different in refractive index. The second coating has a refractive index of up to 1.50 and is made of one selected from the group consisting of SiO.sub.2 and a mixture of SiO.sub.2 and another metal oxide. The reflectance-reducing glass pane optionally further includes a third water-repellent coating which is formed on the second coating. The third coating comprises a silane compound containing a polyfluoroalkyl group. The reflectance of the glass pane is substantially low, with respect to a visible light incident on the glass pane from a side of the first coating at an incidence angle within a range from 40 to 80 degrees.
