Patent ID: 11309456

Abstract:
This invention provides a nitride semiconductor light emitting device in which current concentration is suppressed without excessively increasing resistance at a low cost without increasing a manufacturing process.The planar shape of a mesa portion configuring a nitride semiconductor light emitting device is a shape containing a convex-shaped tip portion 352b formed by a curved line or a plurality of straight lines and abase portion 352a continuous to the convex-shaped tip portion 352b, in which an obtuse angle is formed by adjacent two straight lines in the convex-shaped tip portion formed by the plurality of straight lines. The first electrode layer 4 has visible outlines 411 and 412 along a visible outline 302 of the mesa portion through a gap 9 in planar view. The relationship between a gap W1 in the convex-shaped tip portion 352b and a gap W2 in the base portion 352a is W1>W2.
