Abstract
A low-reflection coated glass sheet of the present invention includes a glass sheet and a low-reflection coating. The low-reflection coating is formed on at least a portion of one principal surface of the glass sheet and contains a binder containing silica as a main component, fine silica particles bound by the binder, and fine titania particles bound by the binder. The low-reflection coating satisfies the following relationships: 30 mass %<CSP<68 mass %; 12 mass %≤CTP<50 mass %; 20 mass %<CBinder<43.75 mass %; CTP/CBinder≥0.6; CBinder<25 mass % in the case of CSP≥55 mass %; and CTP>20 mass % in the case of CSP<55 mass %. The low-reflection coated glass sheet has a transmittance gain of 2.0% or more.
