Problems solved by technology

However, this has the problem of reduced contrast due to stronger reflection of external light from the inner reflective layer
The problem with this is that the organic black matrices in the prior art cannot withstand the crystallization process using an excimer laser
In addition, Cr and Cr oxide (Cr 2 o 3 ) are considered environmental pollutants, making it difficult to still use these materials

Abstract

A sputtering target that can form a black matrix having high-resistance and low-reflection characteristics and an organic light-emitting display device including the black matrix deposited thereby. The sputtering target that is used in a sputtering process for depositing a black matrix contains one selected from the group consisting of Mo-Si-O, W-Si-O and Mo-W-Si-O, the content of the Mo or W being at least 0.5 times the content of the Si.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2012-0089333 filed on Aug. 16, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0002] The present invention relates to a sputtering target and an organic light-emitting display device including a black matrix deposited through the sputtering target, more specifically, to a sputtering target for forming a black matrix and an organic light-emitting display device including a black matrix deposited through the sputtering target. Organic light-emitting display device with black matrix deposited by sputtering target. Background technique [0003] Generally, an organic light emitting device (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 layer and then migrate from the hole injection layer to the organic light-e...
