Organic light emitting diode display and method for manufacturing organic light emitting diode display

1. A method of manufacturing an organic light emitting diode (OLED) display, the method comprising:

forming an organic light emitting element on a first substrate;

forming, on the organic light emitting element, a thin film encapsulation layer that seals the organic light emitting element with the first substrate;

providing a second substrate;

forming a flexible protection layer on the second substrate;

forming a sacrificial layer between the second substrate and the flexible protection layer;

forming a barrier layer on the flexible protection layer;

attaching the first substrate and the second substrate to each other by attaching the barrier layer to the thin encapsulation layer; and

separating the second substrate from the flexible protection layer by removing the sacrificial layer simultaneously from both the second substrate and the flexible protection layer.

2. The method of manufacturing of claim 1 , wherein the flexible protection layer comprises resin.

3. The method of manufacturing of claim 1 , further comprising forming the first substrate on a mother board and separating the mother board from the first substrate, wherein the first substrate comprises flexible resin.

4. The method of manufacturing of claim 1 , wherein the thin film encapsulation layer comprises a single-layered inorganic layer.

5. The method of manufacturing of claim 1 , wherein the flexible protection layer comprises at least one of a polarizing film or a phase difference film.

6. The method of manufacturing of claim 1 , wherein the sacrificial layer comprises at least one of metal, amorphous material, silicon oxide, silicon nitride or metal oxide.
