Display device and method of manufacturing the same

A method of manufacturing a display device including a display area including pixels and a non-display area outside the display area, the method comprising:

• forming a first color conversion layer in an emission area of a first pixel in which light emitting elements are disposed;
• forming a second color conversion layer in an emission area of a second pixel in which the light emitting elements are disposed;
• forming a dummy pattern in non-emission areas of the first pixel and the second pixel and in the non-display area extending from the first pixel;
• integrally forming a photoresist on the first color conversion layer, the second color conversion layer, and the dummy pattern;
• patterning the photoresist using a mask and etching a lower configuration exposed from the photoresist;
• removing a remaining photoresist;
• forming a dummy bank on the dummy pattern;
• and
• forming a planarization layer on the first color conversion layer, the second color conversion layer, and the dummy bank, wherein
• the first pixel is disposed at an outermost side of the display area,
• the second pixel is adjacent to the first pixel, and
• an upper surface of the dummy pattern is lower than an upper surface of the first color conversion layer and an upper surface of the second color conversion layer.
