Abstract
A light source assembly including a light source part, a light guide plate and a light-condensing sheet. The light source assembly generates light and includes at least one light source. The light guide plate includes an incident surface to which the light is incident, an opposing surface which is opposite to the incident surface, and an exiting surface which emits the light, and has a thickness which is gradually increased from the incident surface to the opposing surface. The light-condensing sheet includes a plurality of reverse prism patterns which protrude toward the exiting surface, extend along an arc of a circle, and are arranged in a concentric circle structure.
