Abstract
(EN)
The present invention relates to a low-reflection coating glass. Specifically, a low-reflection coating glass according to the present invention comprises: a glass substrate; and a low-reflection coating layer containing a form in which a first high-refractive index layer, a first low-refractive index layer, a second high-refractive index layer, and a second low-refractive index layer are consecutively laminated, wherein: the first high-refractive index layer and the second high-refractive index layer each have a refractive index of 2.0 to 2.5 and each contain titanium oxide; the first low-refractive index layer and the second low-refractive index layer each have a refractive index of 1.3 to 1.6 and each contain silicon oxide; and the total thickness of the low-reflection coating layer is 300 nm to 600 nm.
