Claim Text:
1. A thin-film transistor (TFT) substrate, comprising: a flexible substrate; a first barrier layer formed on the flexible substrate, the first barrier layer comprising a first silicon oxide layer and a first silicon nitride layer; a second barrier layer formed on the first barrier layer, the second barrier layer comprising a second silicon oxide layer and a second silicon nitride layer; a silicon oxynitride layer interposed between the first silicon nitride layer and the second silicon nitride layer; and a TFT layer formed on the second barrier layer, wherein the second silicon oxide layer is disposed closer to the TFT layer than the first silicon oxide layer, wherein the first silicon nitride layer and the second silicon nitride layer are interposed between the first silicon oxide layer and the second silicon oxide layer, wherein the first silicon nitride layer is in contact with the second silicon nitride layer, and wherein a total thickness of the first and second silicon nitride layers is less than a total thickness of the first and second silicon oxide layers.
