摘要:
A nitride-based semiconductor light-emitting device capable of suppressing complication of a manufacturing process and reduction of luminous efficiency is obtained. This nitride-based semiconductor light-emitting device (50) includes a nitride-based semiconductor device layer (23) formed on a main surface of a (1-100) plane of a substrate (21), having a light-emitting layer (26) having a main surface of a (1-100) plane, a facet (50a) formed on an end of a region including the light-emitting layer (26) of the nitride-based semiconductor device layer (23), formed by a (000-1) plane extending in a direction substantially perpendicular to the main surface ((1-100) plane) of the light-emitting layer (26), and a reflection surface (50c) formed on a region opposed to the facet (50a) of the (000-1) plane, formed by a growth surface of the nitride-based semiconductor device layer (23), extending in a direction inclined at an angle θ1 (about) 62° with respect to the facet (50a).
