Abstract: A light emitting element includes: a substrate; a light emitting unit that is laminated on the substrate; and a thyristor that is laminated on the light emitting unit and performs setting so as to cause the light emitting unit to emit light or increase an amount of emitted light by being turned into an ON state, the thyristor having a low resistance layer with a resistance which does not electrically separate the thyristor at a position where a current flows from an electrode being in contact with the thyristor.

Abstract: A light emitter includes: a substrate; a driving section provided on the substrate; a light source that is provided on the substrate and is driven by the driving section; a cover section through which light emitted from the light source is transmitted and that is disposed in an optical axial direction of the light source; and a support section that is provided on a part of the substrate excluding a part between the driving section and the light source and supports the cover section.

Abstract: A light-emitting element array includes a substrate, plural light-emitting elements arranged on the substrate, plural constriction grooves being provided in a periphery of each of the plural light-emitting elements and forming a current constriction layer that constricts a current flowing through a light-emitting layer by oxidizing the light-emitting layer, and a block separation portion that is provided in a curved shape so as to include at least one inflection point at which a sign of curvature changes along each of positions where the plural light-emitting elements are arranged, and separates the plural light-emitting elements into plural blocks.
