Abstract:
1. A fabricating method of a gas barrier substrate, comprising: forming a de-bonding layer on a carrier; forming a lift-off layer on the carrier; forming a first gas barrier layer on the lift-off layer, the first gas barrier layer having a central bonding surface and a peripheral bonding surface which surrounds the central bonding surface; coating a substrate on the central bonding surface of the first gas barrier layer and bonding the substrate with the central bonding surface, wherein the substrate has a tapered sidewall, and an acute angle is included between the tapered sidewall and the central bonding surface; forming a second gas barrier layer, covering the substrate and the first gas barrier layer, wherein the second gas barrier layer is bonded with the substrate and the peripheral bonding surface of the first gas barrier layer, and a minimum distance from an edge of the substrate to an edge of the first gas barrier layer is greater than a thickness of the first gas barrier layer; and cutting the de-bonding layer, the lift-off layer, the first gas barrier layer, and the second gas barrier layer along a cutting line between the edge of the substrate and an edge of the lift-off layer, so that the lift-off layer is separated from the de-bonding layer.
