Semiconductor light-emitting element, and display device

A semiconductor light-emitting element, comprising:

• a light-emitting layer comprising a first emission region, a second emission region, and a third emission region between the first emission region and the second emission region;
• a passivation layer surrounding the light-emitting layer;
• a first-first non-uniform region under the first emission region of the light-emitting layer;
• a first-second non-uniform region under the second emission region of the light-emitting layer;
• a first uniform region under the third emission of the light-emitting layer;
• a first electrode comprising a second-first non-uniform region, a second-second non-uniform region, and a second uniform region under the first-first non-uniform region, the first-second non-uniform region, and the first uniform region, respectively;
• and
• a second electrode on the light-emitting layer,
• wherein each of the first-first non-uniform region and the first-second non-uniform region comprises a plurality of first negative patterns and a plurality of first protrusions on the plurality of first negative patterns,
• wherein each of the second-first non-uniform region and the second-second non-uniform region comprises a plurality of second negative patterns and a plurality of second protrusions on the plurality of second negative patterns,
• wherein the plurality of second negative patterns have shapes corresponding to shapes of the plurality of first negative patterns, respectively, and
• wherein the plurality of second protrusions have shapes corresponding to shapes of the plurality of first protrusions, respectively.
