Abstract

A light emitting device package including light emitting devices, and optical lenses respectively disposed over the light emitting devices. Further, a respective optical lens includes an extending member extending from a body of the respective optical lens, and including a first portion laterally extending in a first direction substantially perpendicular to the central axis of the respective light emitting device, and a second portion extending towards the substrate in a second direction substantially parallel with the central axis of the respective light emitting device. A vertical cross section of the second portion is substantially symmetrical with respect to an axis that is spaced apart in the first direction from and substantially parallel with the central axis of the respective light emitting device.
