Display panel and manufacturing method thereof

A display panel comprising:

• a base layer;
• a pixel definition layer disposed on the base layer and comprising an emission opening;
• first and second light emitting elements disposed on an upper insulation layer, each of the first and second light emitting elements comprising:
• a first electrode disposed in the emission opening,
• a second electrode disposed on the first electrode, and
• a light emitting layer disposed between the first electrode and the second electrode;
• a separator disposed between the second electrode of the first light emitting element and the second electrode of the second light emitting element, disposed on the pixel definition layer, and comprising a first surface adjacent to the pixel definition layer and a second surface facing the first surface, the separator having a width increasing as being closer to the second surface from the first surface;
• and
• an encapsulation layer covering the separator,
• wherein the separator comprises a base resin and a scattering agent.

A manufacturing method of a display panel comprising:

• providing a preliminary display panel comprising:
• a base layer,
• first and second transistors disposed on the base layer,
• an insulation layer disposed on the first and second transistors,
• a pixel definition layer disposed on the insulation layer and comprising an opening, and
• a first electrode disposed in the opening of the pixel definition layer;
• applying a photosensitive organic composition comprising a base resin and a scattering agent on the pixel definition layer;
• disposing a mask comprising a mask opening on the photosensitive organic composition;
• forming a separator by irradiating light on the photosensitive organic composition through the mask opening to cure a portion of the photosensitive organic composition;
• and
• forming a light emitting layer and a second electrode on the separator and the preliminary display panel,
• wherein the second electrode disposed on the separator and the second electrode disposed on the first electrode are separated from each other.
