Classification: CPC H | IPC H

Claim 9:
10. An image display element comprising:
micro light emitting elements disposed in an array on a driving circuit substrate including a driving circuit configured to supply a current to the micro light emitting elements and cause the micro light emitting elements to emit light,
wherein each of the micro light emitting elements emits light in a direction opposite the driving circuit substrate,
each of the micro light emitting elements includes an excitation light emitting element configured to generate excitation light, a reflective wall surrounding the excitation light emitting element, and a transparent portion disposed inside the reflective wall,
a sidewall of the reflective wall is not in contact with a sidewall of the excitation light emitting element and is inclined to open with respect to a light emission direction of each of the micro light emitting elements,
the transparent portion covers all surfaces of the excitation light emitting element excluding a surface of the excitation light emitting element located closer to the driving circuit substrate, and
the excitation light emitting element includes a main body including a compound semiconductor, a metal electrode disposed on a first side of the main body relatively closer to the driving circuit substrate, and a transparent electrode disposed on a second side of the main body relatively farther from the driving circuit substrate,
wherein a light blocking material having insulation properties is disposed at a bottom portion of the reflective wall, and
the light blocking material is in contact with the metal electrode and the reflective wall.
