Embodiment 1

[0049] The transparent crystallized glass is manufactured by heat-treating lithium aluminosilicate glass containing a nucleating agent at 850°C for 1 hour. The transmittance, reflectance and crystallinity of the manufactured transparent crystallized glass were measured. The maximum visible light transmittance is 87.6%, the reflectance is 8.43%, and the crystallinity is 84%.

Embodiment 2

[0051] The transparent crystallized glass was manufactured by heat-treating glass having the same composition as in Example 1 at 850°C for 2 hours. The transmittance, reflectance and crystallinity of the manufactured transparent crystallized glass were measured. The maximum visible light transmittance is 87.9%, the reflectance is 8.43%, and the crystallinity is 87%.

Embodiment 3

[0053] The transparent crystallized glass was manufactured by heat-treating glass having the same composition as in Example 1 at 900°C for 1 hour. The transmittance, reflectance and crystallinity of the manufactured transparent crystallized glass were measured. The maximum visible light transmittance is 83.6%, the reflectance is 9.06%, and the crystallinity is 88%.

Abstract

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.

Description

[0001] Cross references to related applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0131698 filed on November 20, 2012, the entire content of which is incorporated herein by reference for all purposes. Technical field [0003] The present invention relates to a substrate for an organic light emitting diode (OLED), a method of manufacturing the substrate, and an organic light emitting device having the substrate, and more specifically, to a device that can improve the light extraction efficiency of the organic light emitting device while ensuring transmittance A substrate for an OLED, a method of manufacturing the substrate, and an organic light emitting device having the substrate. Background technique [0004] Generally, an organic light emitting diode (OLED) includes an anode, a light emitting layer, and a cathode. When a voltage is applied between the anode and the cathode, holes are injected from the anode into the hole injection...
