Title: LIGHT-EMITTING ELEMENT AND METHOD FOR MANUFACTURING LIGHT-EMITTING ELEMENT
Abstract:
 The present invention is a light-emitting element having a quaternary light-emitting layer, a first window layer formed on one main-surface side of the quaternary light-emitting layer, and a second window layer formed on the other main-surface side of the quaternary light-emitting layer, wherein the light-emitting element is characterized in that the side surfaces of the quaternary light-emitting layer are further indented toward the inside of the light-emitting element than are the side surfaces of the first and second window layers. This makes it possible to obtain and manufacture a high-brightness light-emitting element in which it is possible to reduce faults where the light-emitting element becomes destroyed and unlit and to suppress variations in light emission output and Vf.
