Abstract
A light emitting device package including a partition structure having first and second surfaces, and first to third light emission windows penetrating through the first and second surfaces, a cell array including first to third light emitting devices on the first surface of the partition structure and overlapping the first to third light emission windows, each of the first to third light emitting devices including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer, first and second wavelength conversion portions filling interiors of the first and second light emission windows, and having a meniscus-shaped interfaces, a first encapsulating portion including a light-transmissive organic film layer that fills the third light emission window and covers the first and second wavelength conversion portions, and a second encapsulating portion covering the first and second encapsulating portions and including a light-transmissive inorganic film layer.
