  • Porous glass substrate for displays and method of manufacturing the same
    Patent number: 8921841
    Abstract: A porous glass substrate for displays and a method of manufacturing the same, with which the optical characteristics of a display such as an organic light-emitting device (OLED) can be improved. The porous glass substrate includes a glass substrate and a porous layer formed in at least one portion of one surface of the glass substrate and extending into the glass substrate, the refractive index of the porous layer being smaller than the refractive index of the glass substrate. The porous layer has a plurality of pores which is formed in the glass substrate such that at least one component of the glass substrate except for silicon dioxide (SiO2) is eluted from the glass substrate.
