Abstract
A method of manufacturing a display device includes forming an organic layer on an encapsulation layer disposed on a light emitting layer, forming a slit layer on the organic layer, where a slit exposing at least a portion of a top surface of the organic layer is formed in the slit layer, forming a first trench by performing a primary etching on the organic layer by using the slit layer as a mask, forming a first inorganic protective layer covering a side surface of the first trench, forming a second trench extending from the first trench by performing a secondary etching on the organic layer by using the slit layer as a mask, and forming a light blocking material filling the first trench and the second trench.
