Display device and manufacturing method thereof

A display device comprising:

• a substrate;
• an insulation layer that is positioned on the substrate and includes a plurality of openings;
• a plurality of emission layers that are positioned in the openings;
• and
• a plurality of spacers that are positioned on the insulation layer,
• wherein an area where the plurality of emission layers are positioned defines a plurality of light emitting regions on a plane,
• at least one of the spacershas a shape of a regular polygon having five or more sides, or a regular polygon with at least one rounded corner and five or more sides, and
• a number of the plurality of the spacers positioned in a predetermined region is at least 30% of a number of the plurality of the light emitting regions arranged in the predetermined region.

A manufacturing method of a display device, comprising:

• forming a thin film transistor on a substrate;
• forming a plurality of pixel electrodes on the thin film transistor;
• forming an insulation layer including an organic material on the plurality of pixel electrodes and a plurality of spacers positioned on the insulation layer;
• disposing a mask including a plurality of openings on the plurality of spacers;
• and
• forming a plurality of emission layers in an opening of the insulation layer through the plurality of openings of the mask,
• wherein a shape of the spacer is one of a circule, a regular polygon with five or more sides, or a regular polygon with at least one rounded corner and five or more sides,
• a planar area of at least one of the spacers is larger than a planar area of a smallest light emitting region among the plurality of light emitting regions, and
• a number of the plurality of the spacers positioned in a predetermined region is at least 30% of the number of a plurality of the light emitting regions arranged in the predetermined region.
