Abstract
An organic light-emitting device (OLED) which can improve the light extraction efficiency of the OLED, a method of fabricating the same and an OLED including the same. The light extraction substrate is disposed on one surface of an OLED through which light generated from the OLED is emitted outward, and includes a base substrate and a light extraction layer formed on the base substrate. The light extraction layer has therein a plurality of pores which is formed on the base substrate such that the base substrate forms a bottom surface of the plurality of pores.
Claims8
A method of fabricating a light extraction substrate which is disposed on one surface of an organic light-emitting device through which light generated from the organic light-emitting device is emitted outward, the method comprising:
- forming a frit powder by melting and pulverizing a glass;
- forming a frit paste by mixing the formed frit powder into an organic solvent to which an organic binder is added;
- applying the formed frit paste on a base substrate by screen printing, thereby printing a plurality of bead structures on the base substrate;
- and
- firing the printed frit paste to form a light extraction layer in which a plurality of pores is formed, each pore having the base substrate as a bottom surface of the pore and extending into a respective bead of a plurality of beads, each bead formed from and corresponding to a respective bead structure of the printed bead structures.
