摘要： The present invention relates to a display device, a backlight unit, a light emitting module, and a lens. The light emitting module according to an embodiment of the present invention may include: a light emitting device; and a lens disposed on the light emitting device to spread light emitted from the light emitting device, wherein the lens includes a light entering part on which the light emitted from the light emitting device is incident and a light exiting part through which the incident light is emitted, wherein each of the light entering part and the light exiting part has a shape having a major axis and a minor axis in plan view, and the major axis of the light entering part is orthogonal to the major axis of the light exiting, and wherein the light entering part includes a light incident vertical surface extending from a lower surface of the lens and a light incident inclined surface extending upward from the light incident vertical surface. According to the present invention, since a distribution of light emitted from the light emitting module may have a rectangular shape, there is an effect that uniform light may be emitted to the outside by combination with the distribution of light emitted from adjacent light emitting modules.

摘要： This luminous flux control member (300) has: an incidence surface (320) through which light emitted from a light-emitting element (220) enters; an emission surface (330) through which the light entering from the incidence surface is emitted to the outside; and multiple ridges (352) that are formed on the back side so as to surround the central axis (CA) and that have a substantially triangular cross-sectional shape. Each of the multiple ridges (352) has a first reflecting surface (352a), a second reflecting surface (352b), and a ridge line (352c) which is the line of intersection of the first reflecting surface (352a) and the second reflecting surface (352b). An imaginary line containing the ridge lines (352c) intersects the central axis (CA) at a position closer to the front side than the ridge lines (352c).
