Apparatus for and method of crystallizing active layer of thin film transistor

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.

Light source assembly and display apparatus having the same

A backlight assembly and a display device having the same are provided. The backlight assembly includes a first substrate, point light sources disposed upon the first substrate and an optical member covering the point light sources to guide light emitted from the point light sources, wherein the first substrate has recessed portions, and the point light sources are positioned within the recessed portions.

Backlight assembly and display device having lower profile and/or reduced weight

A light guiding bar includes first and second light incident portions, a light exit portion and a reflecting portion. The first and second light incident portions are at opposite ends of the light guiding bar and receive light. The light exit portion extends in a first direction, and partially totally reflects and partially emits the light according to an incident angle. The reflecting portion extends in the first direction, is adjacent to the light exit portion and includes a plurality of reflecting surfaces. Each of the reflecting surfaces has a wedge shape and reflects the light in a direction inclined with respect to a second direction substantially perpendicular to the first direction. The light incident into the first and second light incident portions and directly on the light exit portion is totally reflected by the light exit portion.
