Display apparatus

A display apparatus comprising:

• a plurality of first electrodes disposed on a substrate;
• a plurality of light-emitting elements disposed on the plurality of first electrodes;
• a first optical layer disposed between the plurality of light-emitting elements;
• a second electrode disposed on the plurality of light-emitting elements;
• and
• a second optical layer covering the first optical layer,
• wherein the second electrode comprises a first area disposed on the plurality of light-emitting elements and a second area extending outward from the first optical layer,
• wherein the second optical layer is disposed on the second area,
• wherein the second area of the second electrode comprises protruding portions extending to at least one of areas between a plurality of signal wires, and
• wherein one of the protruding portions is electrically connected to a contact electrode.

A display apparatus comprising:

• a plurality of first electrodes on a substrate;
• a plurality of light-emitting elements on the plurality of first electrodes;
• a first optical layer disposed between the plurality of light-emitting elements;
• a second electrode on the plurality of light-emitting elements;
