SUBSTRATE FOR OLED, METHOD OF FABRICATING THE SAME AND ORGANIC LIGHT-EMITTING DEVICE HAVING THE SAME

摘要

A substrate for an organic light-emitting diode (OLED) which can improve the light extraction efficiency of the organic light-emitting device while securing transmittance, a method of fabricating the same, and an organic light-emitting device having the same. The substrate for an OLED is a substrate on which the OLED is to be deposited. The substrate is made of transparent crystallized glass in which a number of crystal grains are distributed.
