Organic light emitting device and manufacturing method thereof

A method for manufacturing an organic light emitting device, comprising:

• forming an organic light emitting display panel comprising a flexible substrate provided on a support substrate, an organic light emitting element on the flexible substrate, and a thin film encapsulating film covering the organic light emitting element;
• detaching the support substrate from the organic light emitting display panel;
• attaching a bottom protecting film to a bottom of the organic light emitting display panel, the bottom protecting film comprising a light blocking layer for blocking external light and an adhesive layer being between the light blocking layer and the flexible substrate;
• and
• cutting the organic light emitting display panel into a plurality of organic light emitting devices,
• the method further comprising attaching a top protecting film on a thin film encapsulating film of the organic light emitting display panel before detaching the support substrate from the organic light emitting display panel, and
• the method further comprising removing the top protecting film.
