Light emitting unit, backlight assembly including the same, and method of manufacturing the same

摘要

A light emitting unit may include a housing having a bottom portion parallel to an xz plane and an opened top opposite to the bottom portion, a light emitting chip on the bottom portion and generating light, and a lens which overlaps the opened top of the housing. The lens may have a convex structure with respect to the xz plane when viewed from a cross section parallel to an xy plane and a concave structure with respect to the xz plane when viewed from a cross section parallel to a yz plane.

1. A light emitting unit comprising:
a housing including a bottom portion parallel to an xz plane, an opened top opposite to the bottom portion, and a singular opening defined in the bottom portion; a light emitting chip which is on the bottom portion and generates light; a first electrode and a second electrode on the bottom portion and spaced apart from each other; and a lens which overlaps the opened top of the housing, wherein the lens includes:
a convex structure with respect to the xz plane when viewed from a cross section parallel to an xy plane, anda concave structure with respect to the xz plane when viewed from a cross section parallel to a yz plane,x, y and z being directions perpendicular to each other, respectively, wherein the singular opening defined in the bottom portion of the housing exposes a lower surface of both the first and second electrodes.
