Abstract

A semiconductor light emitting device includes a package body including a concave portion surrounded by sidewalls, a light emitting diode (LED) chip on a mounting surface of the concave portion, a lead frame in the package body and electrically connected to the LED chip, a wavelength conversion layer in the concave portion and surrounding the LED chip, the wavelength conversion layer being surrounded by the sidewalls of the package body and including a wavelength conversion material, and a transparent resin layer on the wavelength conversion layer, the transparent resin layer having first opposite side surfaces exposed through sides of the package body and spaced apart from each other along a first direction parallel to the mounting surface, and second opposite side surfaces contacting an inner surface of the package body and spaced apart from each other in a second direction parallel to the mounting surface.
