Light emitting substrate with groove in electrode planarization layer for LED and display device

A light emitting substrate, comprising:

• a base substrate;
• an electrode planarization layer, located on the base substrate;
• and
• an electrode layer, located at a side of the electrode planarization layer away from the base substrate,
• wherein the electrode layer comprises a first electrode and a second electrode, the first electrode comprises at least one first electrode strip, and the second electrode comprises at least one second electrode strip,
• the at least one first electrode strip and the at least one second electrode strip are spaced and alternately arranged in a first direction, each of the at least one first electrode strip and each of the at least one second electrode strip extend along a second direction, and the second direction intersects with the first direction,
• the electrode planarization layer comprises a first groove between a first electrode strip and a second electrode strip which are adjacent to each other, and the first groove is configured to accommodate a light emitting diode;
• the first electrode comprises a plurality of first electrode strips, and the second electrode comprises a plurality of second electrode strips, and the plurality of first electrode strips and the plurality of second electrode strips are alternately arranged in the first direction;
• at least one of the first groove is arranged between any one of the plurality of first electrode strips and a second electrode strip which is adjacent to the any one of the plurality of first electrode strips in the first direction.
