1. A reflectance-reducing glass pane comprising:

  • a transparent glass substrate having first and second major surfaces opposed to each other;

    a first reflectance-reducing coating formed directly on the first major surface of said glass substrate, said first coating having at least two metal-oxide layers which are different in refractive index; and

    a surface reflectance-reducing coating formed directly on the second major surface of said glass substrate, said second coating having a refractive index within a range from 1.43 to 1.47 and a thickness within a range from 105-130 nm, and being made of a member selected from the group consisting of SiO2 and a mixture of SiO2 and another metal oxide.
