Abstract:
1. A gas barrier substrate disposed on a carrier, the gas barrier substrate comprising: a de-bonding layer disposed on the carrier, a portion area of the carrier being exposed by the de-bonding layer; a lift-off layer covering the de-bonding layer and the portion area of the carrier exposed by the de-bonding layer; a first gas barrier layer covering 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, an area of the central bonding surface is smaller than an area of the de-bonding layer; a substrate bonded with the central bonding surface of the first gas barrier layer, wherein the substrate has a tapered sidewall, and an acute angle is included between the tapered sidewall and the central bonding surface; and 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.
