Abstract

A barrier film composite includes a heat-shrinkable layer having a conformable surface conforming to a surface shape of an object in contact with the heat-shrinkable layer, and a flat surface disposed opposite to the conformable surface; and a barrier layer having a smaller thickness than the heat-shrinkable layer and disposed flat on the flat surface of the heat-shrinkable layer.

First claim

What is claimed is:

1. A method of manufacturing a display apparatus, the method comprising:
forming a light-emitting device on a substrate;
independently from the formation of the light-emitting device, providing a barrier film composite comprising a heat-shrinkable layer having a predetermined thickness and a barrier layer that is disposed on a surface of the heat-shrinkable layer, the heat-shrinkable layer having a conformable surface conforming to a shape of a surface of an object when the surface of the object is in direct physical contact with the heat-shrinkable layer and a flat surface disposed opposite to and spaced apart from the conformable surface, the barrier layer extending throughout an entirety of the flat surface disposed opposite to and spaced apart from the conformable surface; and
aligning the barrier film composite to the substrate in such a manner that the heat-shrinkable layer contacts the light-emitting device and simultaneously applying pressure and heat to the heat-shrinkable layer to remove an air gap between the light-emitting device and the heat-shrinkable layer,
wherein a minimum thickness of the heat-shrinkable layer is larger than a thickness of the barrier layer, and the barrier layer is disposed farther from the light-emitting device than the heat-shrinkable layer.

2. The method of claim 1 , wherein in the step of applying heat to the heat-shrinkable layer, the heat-shrinkable layer shrinks so that a surface of the heat-shrinkable layer physically contacting the light-emitting device conforms to a surface shape of the light-emitting device and removes an air gap between the light-emitting device and the heat-shrinkable layer.

3. The method of claim 1 , wherein in the step of aligning the barrier film composite to the light-emitting device, applying a predetermined pressure to the barrier film composite.

4. The method of claim 1 , wherein the barrier film composite comprises a plurality of alternating layers of the heat-shrinkable layer and the barrier layer.

5. The method of claim 1 , wherein in the forming of the light-emitting device, the light-emitting device comprises an organic light-emitting device.
