Light-emitting element wafer, light emitting element, electronic apparatus, and method of producing light-emitting element wafer

A light emitting element, comprising:

• a luminescent layer that has oppositely facing first and second surfaces, the first surface having a first concavo-convex structure;
• a first inorganic film on the first surface of the luminescent layer, the first inorganic film having a second concavo-convex structure with a shape conforming to a shape of the first concavo-convex structure;
• a second inorganic film on the second surface of the luminescent layer;
• a first electrode for the light-emitting element on the first surface, the first electrode being exposed through and in addition to the first inorganic film or being the first inorganic layer film itself;
• a second electrode for the light-emitting element on the second surface of the luminescent layer, the second electrode being exposed through the second inorganic film;
• and
• an external connection terminal that is electrically connected to the second electrode,
• wherein,
• the second inorganic film includes (a) a first insulating layer on the second surface of the luminescent layer, (b) a metal layer on the first insulating layer, and (c) a second insulating layer on the metal layer.
