NITRIDE SEMICONDUCTOR LIGHT EMITTING ELEMENT, LIGHT EMITTING ELEMENT, ELEMENT LAMINATE, AND LIGHT EMITTING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nitride semiconductor light emitting element in which homogeneous emission can be obtained over the entire light emitting surface.

SOLUTION: A laminate constituted by laminating an n-type layer, an active layer and a p-type layer is provided on a substrate. The laminate comprises n-electrode formation regions parallel to each other in which an n-type layer surface is exposed to form line shaped n-side electrodes. The n-line electrodes are respectively formed on the n-electrode formation regions, and a light-transmitting electrode is formed on almost over the entire surface of the p-type layer, and the n-line electrodes are arranged at regular intervals while being separated from one another, and n-pad electrodes are formed at one end of each of the n-line electrodes. Line shaped current diffusion conductors are formed on the light-transmitting electrode as to be arranged alternately with the n-line electrodes and as to be at equal distances from the adjoining n-line electrode. At one end of the current diffusion conductors, p-pad electrodes are formed.
