Display device and method of manufacturing the same

A display device comprising:

• a display area located over a substrate, the display area including a plurality of pixels of which each includes a first electrode, a second electrode, and an intermediate layer including an emission layer and arranged between the first electrode and the second electrode;
• a pixel-defining layer covering edges of the first electrode of each of the plurality of pixels;
• a spacer arranged on the pixel-defining layer;
• a planarization layer arranged between the pixel-defining layer and the substrate;
• a thin-film encapsulation layer arranged on the pixel-defining layer and the spacer and including a first inorganic encapsulation layer, a second inorganic encapsulation layer, and an organic encapsulation layer located between the first inorganic encapsulation layer and the second inorganic encapsulation layer;
• a hole arranged apart from the first electrode, the hole being formed in the spacer and the pixel-defining layer and extending into the planarization layer;
• and
• an etching prevention layer arranged under a bottom surface of the hole,
• wherein the intermediate layer and/or the second electrode are located inside of the hole and on a top of the spacer, and the intermediate layer and/or the second electrode are not connected between the inside of the hole and the top of the spacer, and
• the intermediate layer contacts the etching prevention layer.

A display device comprising:

• a display area located over a substrate and including a plurality of pixels, each of the plurality of pixels including a first electrode, a second electrode, and an intermediate layer including an emission layer and located between the first electrode and the second electrode;
• a non-display area located over the substrate and located outside the display area;
• a thin-film encapsulation layer encapsulating the plurality of pixels and including a first inorganic encapsulation layer, a second inorganic encapsulation layer, and an organic encapsulation layer located between the first inorganic encapsulation layer and the second inorganic encapsulation layer;
• a pixel-defining layer covering edges of the first electrode and extending from the display area to the non-display area;
• a first spacer located on the pixel-defining layer in the display area;
• a second spacer located on the pixel-defining layer in the non-display area, including a material the same as that of the first spacer, and including a first portion and a second portion, the first portion of the second spacer having a width increasing toward the substrate, and the second portion of the second spacer being arranged between the first portion of the second spacer and the substrate and having a width decreasing toward the substrate;
• a planarization layer arranged between the pixel-defining layer and the substrate;
• and
• a hole located in the non-display area, the hole being formed in the second portion of the second spacer and the pixel-defining layer and extending into the planarization layer.
