Display device, electronic device including the same, and method of manufacturing the display device

A display device comprising:

• a base substrate;
• a circuit element layer disposed on the base substrate and comprising a pixel circuit;
• a light-emitting element disposed on the circuit element layer, the light-emitting element comprising:
• a pixel electrode electrically connected to the pixel circuit;
• a light-emitting pattern disposed on the pixel electrode;
• and
• an opposite electrode facing the pixel electrode across the light-emitting pattern;
• a conductive partition wall comprising:
• a first conductive pattern including a side surface electrically connected with the opposite electrode;
• and
• a second conductive pattern disposed on the first conductive pattern and protruding from the side surface;
• an encapsulation pattern comprising:
• a first portion disposed on the light-emitting element and covering the light-emitting element;
• a second portion extending from the first portion and disposed around a side surface of the second conductive pattern;
• and
• a third portion extending from the second portion away from the light-emitting element;
• and
• a reflection-reducing layer surrounding the third portion and having a lower reflectance than a reflectance of the conductive partition wall.
