Abstract

A display device includes a substrate which includes a base part and a protruding pattern which protrudes from the base part, a pixel electrode which is on the protruding pattern, a pixel defining layer which is d on the pixel electrode and exposes the pixel electrode, a light emitting layer which is on the pixel electrode exposed by the pixel defining layer, a common electrode which is on the light emitting layer, a first inorganic encapsulation layer which is on the common electrode, a second inorganic encapsulation layer which is on the first inorganic encapsulation layer, and an overcoat layer which is on the second inorganic encapsulation layer. The pixel defining layer defines a light emitting area, and the first inorganic encapsulation layer and the second inorganic encapsulation layer are in direct contact with each other in the light emitting area.

First claim

What is claimed is:

1 . A method of providing a display device, the method comprising:
providing a substrate comprising a base part, and a protruding portion which is curved from the base part; providing on the protruding portion of the substrate:
a display element including a pixel electrode and a common electrode;
a first inorganic encapsulation layer which is on the display element; and
an organic photosensitive layer which is on the first inorganic encapsulation layer; and
providing exposure and development of the organic photosensitive layer to define an organic layer on the protruding portion of the substrate.

2 . The method of claim 1 , wherein
the providing of the display element comprises providing a pixel defining layer which is on the pixel electrode, defines a light emitting area and exposes the pixel electrode to outside the pixel defining layer at the light emitting area, and the method further comprises providing a second inorganic encapsulation layer which is between the first inorganic encapsulation layer and the organic photosensitive layer and in direct contact with the first inorganic encapsulation layer at the light emitting area which is defined by the pixel defining layer.

3 . The method of claim 2 , wherein
the providing of the substrate provides the protruding portion in plural including a plurality of protruding portions each curved from the base part, the plurality of protruding portions are disconnected from each other along the base part, and the first inorganic encapsulation layer and the organic layer which is defined from the organic photosensitive layer are each provided on the plurality of protruding portions of the substrate.
