Electroluminescent element capable of realizing high luminance and high resolution and electroluminescent display device having same

An electroluminescent element comprising:

• a first light emitting element provided with a first light emitter emitting light of a first color, and a second light emitter emitting light of a second color different from the first color, the first light emitter and the second light emitter being disposed to be adjacent to each other;
• and
• a second light emitting element provided with a third light emitter disposed to overlap the first light emitter and emitting light of the second color, and a fourth light emitter disposed to overlap the second light emitter and emitting light of a third color, the third light emitter and the fourth light emitter being disposed to be adjacent to each other,
• wherein light emitted from the first light emitting element is emitted through the second light emitting element,
• wherein the first light emitting element includes a first electrode disposed on a first surface of the first light emitter and the second light emitter, and a second electrode disposed on a second surface opposite to the first surface of the first light emitter and the second light emitter so as to face the first electrode,
• the second light emitting element includes a third electrode disposed on a first surface of the third light emitter and the fourth light emitter, and a fourth electrode disposed on a second surface opposite to the first surface of the third light emitter and the fourth light emitter so as to face the third electrode;
• and
• the second electrode and the third electrode are adhered to each other, and
• wherein the first electrode is a first anode electrode that reflects light from the first and second light emitters,
• the second electrode is a first cathode electrode that transmits a part of each light emitted from the first and second light emitters,
• the third electrode is a second cathode electrode that transmits a part of light emitted from the first cathode electrode, and
• the fourth electrode is a second anode electrode that transmits light emitted from the third light emitter.

An electroluminescent element comprising:

• a first light emitting element provided with a first light emitter emitting light of a first color, and a color filter layer disposed to overlap the first light emitter and having a first color filter of a second color different from the first color and a second color filter of a third color different from the first and second colors, the first color filter and the second color filter being disposed to be adjacent to each other;
• and
• a second light emitting element provided with a second light emitter disposed to overlap the first light emitter and the color filter layer and emitting light of a fourth color different from the first to third colors,
• wherein light emitted from the first light emitting element is emitted through the color filter layer and the second light emitting element.
