Description

technical field [0001] Embodiments of the present disclosure relate to a light emitting element with improved luminous efficiency. Background technique [0002] A light emitting diode (LED) is a light emitting element that emits light when a current is applied thereto. LEDs can efficiently emit light, and thus have an excellent energy-saving effect. [0003] Recently, the problem of brightness of LEDs has been significantly solved, and LEDs are applied to various devices such as backlight units of liquid crystal display (LCD) devices, electronic signs, indicators, home appliances, and the like. [0004] The LED includes a first semiconductor layer, a second semiconductor layer, and an active layer disposed between the first semiconductor layer and the second semiconductor layer, and an electrode pad is formed by etching a part of a light emitting structure. [0005] In this case, a current crowding phenomenon in which luminescent coupling is relatively strong occurs in the...
