Provided are a backlight and a liquid crystal display device including the same. The backlight unit includes a light source assembly which emits light; a light guide plate which receives at a light incident surface thereof light from the light source assembly; and a bottom chassis having a bottom unit on which the light guide plate is disposed. The bottom unit of the bottom chassis has a first bottom portion which is arranged in the vicinity of the light incident surface and has a first recess, a second bottom portion which is bent diagonally to the cross sectional surface and has a second recess, and a third bottom portion which is bent at the second bottom portion in the direction parallel to the first bottom portion and disposed higher than the first bottom portion. A light absorbing member is disposed in the first and second recesses.

Backlight unit including absorbing member at least partially recessed in bottom chassis and liquid crystal display device including the same

A backlight assembly is provided. The backlight assembly includes a light source, a light guide plate, a light collimation unit, and a guide groove. The light guide plate faces the light source in a first direction. The light guide plate includes a first surface on which light emitted from the light source is incident on and a second surface through which the incident light is emitted. The light collimation unit protrudes from an upper surface of the light guide plate and faces the light source. The guide groove is formed in a lower surface of the light guide plate along the first surface of the light guide plate.

Backlight assembly and display device having the same

A light guide panel, back light assembly and display apparatus are provided. According to an aspect of the inventive concept, there is provided the light guide panel which includes a top surface, a bottom surface, and four side surfaces, and one of the four side surfaces may be a light incident surface.

Light guide panel, back light assembly and display apparatus each having the light guide panel and method of manufacturing the light guide panel

A display device is provided. The display device includes: a display panel; a light source assembly; a light guide plate (LGP); a mold frame; and a bottom chassis. The light source assembly includes a light source configured to generate light and a circuit board on which the light source is mounted. The LGP includes an incident surface upon which the light generated by the light source is incident and an exit surface configured to output the light incident through the incident surface toward the display panel. The mold frame includes a sidewall and a protrusion which protrudes inward from the sidewall. The bottom chassis includes a bottom portion and a sidewall portion and houses the mold frame, the LGP and the light source assembly. The display panel is placed on an upper surface of the protrusion, at least a portion of the circuit board is disposed between a lower surface of the protrusion and the bottom portion, and an upper surface of the light source does not overlap the protrusion.

Display device

Disclosed is a light guide plate including a base sheet and a first light transmissive adhesive layer disposed on a surface of the base sheet. The first light transmissive adhesive layer together with the base sheet define a light entrance portion. The thickness of the first light transmissive adhesive layer becomes gradually smaller from the light entrance portion toward a center portion of the base sheet. A backlight assembly includes the light guide plate.
