Light emitting element, display element, and method for producing light emitting element

A display element comprising

• a plurality of light emitting elements arranged on a plane, each of the light emitting elements including
• a lower electrode disposed on a support layer,
• first members disposed on the support layer so as to surround the lower electrode to form a recess structure, the first members each having a void inside,
• an organic layer disposed on the lower electrode and the first members and along the recess structure, the organic layer containing a luminescent organic compound,
• an upper electrode disposed on the organic layer and along the recess structure, and
• a second member disposed above the upper electrode such that the recess structure is embedded in the second member, the second member having a higher refractive index than the first members.

A method for producing a light emitting element, the method comprising:

• forming a lower electrode on a support layer;
• forming first members positioned to surround the lower electrode on the support layer so as to form a recess structure having the lower electrode as a bottom surface, the first members each having a void inside;
• forming an organic layer on the lower electrode and the first members and along the recess structure, the organic layer containing an organic luminescent material;
• forming an upper electrode on the organic layer and along the recess structure;
• and
• forming a second member above the upper electrode such that the recess structure is embedded in the second member, the second member having a higher refractive index than the first members.
