    Abstract: An edge-lit light source includes at least two light guide layers and one or more light-emitting elements. Side surfaces of each layer include a light incident surface and a light exit surface. The layer includes a bending region. A light-emitting surface of each element faces a light incident surface of at least one layer. The layer includes first and second light guide portions. An end surface of the first light guide portion is the light exit surface. The second light guide portion includes at least two light guide bars each including a bending portion and an extending portion. A surface of the extending portion is a light incident sub-surface. The light-emitting surface of each element faces at least one light incident sub-surface. Second light guide portions of the at least two layers are arranged in a second direction perpendicular to a thickness direction of the first light guide portion.
