Abstract
A light emitting element may include an emission stacked pattern including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer that are stacked in a longitudinal direction of the emission stacked pattern. The active layer may include a first surface that is in contact with the first conductive semiconductor layer in the longitudinal direction of the emission stacked pattern, and a second surface that is opposite the first surface and is in contact with the second conductive semiconductor layer. The first conductive semiconductor layer may include at least one n-type semiconductor layer, and the second conductive semiconductor layer may include at least one p-type semiconductor layer. Further, the first surface of the active layer may be located at a point corresponding to −20% to +20% of half of a total length of the emission stacked pattern in the longitudinal direction of the emission stacked pattern.
