1. A light-emitting element, comprising:
a light-emitting section including a plurality of light-emitting regions,
wherein the light-emitting section includes
a first electrode shared in the light-emitting region,
an organic layer formed on the first electrode and including a light-emitting layer including an organic light-emitting material, and
a second electrode formed on the organic layer,
wherein the light-emitting section further includes a light reflective layer below the first electrode, and resonates light emitted by the light-emitting layer between an interface and the light reflective layer, the interface being between the second electrode and the organic layer, the light-emitting section emitting a portion of the light from the second electrode, and
an insulating layer is formed between the first electrode and the organic layer, the insulating layer being provided with an opening defining the light-emitting region; and
one or a plurality of microlens members controlling a traveling direction of light emitted from each of the light-emitting regions.
