Abstract:
A semiconductor light emitting device includes a recess portion defined by a pair of opposing first side wall portions and a pair of opposing second side wall portions extending between the first side wall portions and shorter than the first side wall portions. Light emitting elements are arranged on the bottom surface of the recess portion in a direction of the first side wall portions. The light emitting elements include a first light emitting element for emitting light of a first color and a second light emitting element for emitting light of a second color different from the first color and placed closest to the second side wall portion among the light emitting elements. A resin portion containing a phosphor for wavelength-converting a part of the light of the second color into a complementary color of the light of the second color is filled into the recess portion.
