PURPOSE: An anti-reflective glass is provided to increase transmittance and the reflectivity without the formation of a separate coating layer by forming a porous structure of a nano-size on the surface of the glass through an alkaline bath-based etching process. CONSTITUTION: A porous structured layer is formed on an anti-reflective glass substrate, and pores of nano-sizes are regularly distributed on the surface of the glass substrate through an etching process. The pore size of the porous structure is smaller than the wavelength of incident light. The pore size of the porous structure is 1/4 or less of the wavelength of the incident light. The thickness of the porous structured layer is between 70 and 480nm. The glass substrate is soda lime glass or alumina silicate glass. The porous structure is formed based on an alkali solution.
