摘要： A substrate for an organic light-emitting device (OLED) with enhanced light extraction efficiency, a method of manufacturing the same and an OLED having the same, in which the light extraction efficiency is enhanced, thereby reducing the phenomenon of color shift in which color changes depending on the position of a viewer within the viewing angle. The transparent substrate used in an OLED includes an anode, an organic light-emitting layer and a cathode which are stacked on each other, the transparent substrate comprising a porous layer in at least one portion of one surface thereof that adjoins the organic light-emitting device, a refractive index of the porous layer being smaller than a refractive index of the transparent substrate.

摘要： 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.
