Claim 17:
18. 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 emission layer included in the main body is disposed in a region of the main body close to the second side,
a first drive electrode and a second drive electrode are provided on the driving circuit substrate, wherein
the first drive electrode is provided between the drive circuit substrate and the metal electrode and is electrically connected to the metal electrode, and
the second drive electrode is provided between the drive circuit substrate and the reflective wall and is electrically connected to the transparent electrode.
