摘要（英）：
A light source module for a backlight unit according to the present invention includes a plurality of lens members disposed on a printed circuit board so as to individually cover each of a plurality of light emitting members. Each of the plurality of lens members has a first lens part which has a short axis and a parabolic surface and covers the light emitting member, and a second lens part which includes a curved surface part with a curved shape protruding from the short axis of the first lens unit and a light emitting part provided on the first lens unit. Accordingly, the present invention can emit straight light to an incident side of a light guide plate and prevent a hot spot phenomenon.COPYRIGHT KIPO 2017
