Abstract

This invention provides a silica gel capable of manufacturing a low-refractive-index layer that achieves both low refractive index and low haze value. The silica gel of this invention is characterized in that it is manufactured by polymerizing raw materials in the presence of a catalyst, wherein the molecular volume of the catalyst in dimethyl sulfoxide is less than 100-150 cm³ / mol.
