Abstract:
1. A light-emitting unit comprising: a first light-emitting element over an insulating surface; a second light-emitting element over the insulating surface; a separation layer; a first partition wall; and a second partition wall, the first light-emitting element comprising: the second light-emitting element comprising: wherein: the first partition wall covers an edge portion of the first electrode; the second partition wall is formed over the third electrode; the first electrode and the third electrode are island-shaped; the first electrode and the third electrode are formed from the same layer that is capable of transmitting light emitted by the first light-emitting layer; the first partition wall and the second partition wall are formed from the same layer; the second electrode and the fourth electrode are formed from the same layer; the first light-emitting layer is at least partially in direct contact with each of a top surface of the first partition wall, a side surface of the first partition wall, a top surface of the third electrode, a side surface of the third electrode and a part of the insulating surface; the part of the insulating surface is between the first partition wall and the third electrode; the separation layer is formed over the third electrode; the separation layer comprises a leg portion and a stage portion over the leg portion; a projected area of the stage portion is larger than a projected area of the leg portion; a first edge portion of the second partition wall is covered with the second light-emitting layer, and a second edge portion of the second partition wall is in direct contact with the separation layer; the second electrode is configured to extend beyond the edge portion of the first electrode with the first partition wall interposed therebetween; and the second electrode is electrically connected to the third electrode in a region overlapping with the stage portion.
