PURPOSE: A light emitting device package is provided to reduce the number of mounted emitting devices by having a directional angle over 130 degrees by enlarging the diffusion distribution of light coming from a light emitting device. CONSTITUTION: A lens(30) is mounted on a substrate in order to cover and seal a light emitting device. An accommodating groove(31) is formed on a lower portion of the lens. A concave portion(32) is formed on an upper side of the lens. The concave portion has the radius of curvature on an optical axis of the lens. The concave portion is formed to be depressed from the upper side to the lower portion.
