1. A display device comprising:
a substrate comprising a display area and a non-display area which is adjacent to the display area; and
within the display area:
an emission area provided in plural including emission areas;
a non-emission area between the emission areas, the non-emission area including:
a pixel defining layer defining a first opening,
a spacer spaced apart from the pixel defining layer along the substrate, and
the pixel defining layer and the spacer including different materials from each other, and
each emission area including a light emitting element comprising:
a first electrode exposed to outside the pixel defining layer by the first opening; and
a light emitting layer in the first opening and facing the first electrode,
wherein
the pixel defining layer and the spacer each includes a top surface which is furthest from the substrate and a height of the top surface from the substrate, and
the height of the top surface of the spacer is greater than the height of the top surface of the pixel defining layer.
