A backlight unit for a display device includes a light guide plate; a reflective sheet under the light guide plate; a lamp at least one side of the light guide plate and providing a light into the light guide plate; and an optical sheet disposed on the light guide plate and including a first lenticular sheet, the first lenticular sheet including a base film for diffusing the light through the light guide plate, a first lenticular lens disposed on a front surface of the base film and having a half-cylinder shape and a first printing pattern on at least one edge of a rear surface of the base film.

Backlight unit and liquid crystal display module including the same

A display device and a method of fabricating a reflective sheet for the same are provided. The display device includes: a display panel to display an image, a plurality of light emitting diodes (LEDs) to: generate and supply light to the display panel, a light guide plate to guide the light to the display panel, and a reflective sheet to reflect light toward a cover bottom below the LEDs toward the light guide plate, the reflective sheet including: a reflective layer, first and second skin layers respectively on upper and lower portions of the reflective layer, the first and second skin layers each including an embossing surface including a plurality of first reflective patterns to: prevent adhesion between the reflective layer and the light guide plate, and increase efficiency of light, and the reflective layer including a plurality of second reflective patterns, each including a filler in an air layer.

Display device and method for fabricating reflective sheet for the same

A light guide plate for a backlight unit of a liquid crystal display device includes one side surface where light from a first light source is incident; the other side surface opposite to the one side surface; a front surface combining the one and the other one side surfaces; and a rear surface including a plurality of light guide patterns, each of the plurality of light guide patterns including a protruding portion and a groove portion, wherein one of the protruding portion and the groove portion is positioned at a center of the other one of the protruding portion and the groove portion.

Light guide plate and liquid crystal display device including the same

A liquid crystal display device capable of preventing a split between a light guide plate and a prism sheet disposed at an upper side thereof and improving concentration efficiency, the device including a liquid crystal panel configured to represent an image, a lamp disposed below the liquid crystal panel to provide light to the liquid crystal panel, a light guide plate having the lamp disposed at least at one side thereof, and a birefringence optical sheet disposed between the liquid crystal panel and the light guide plate, and having a first prism pattern with a first refractive index, the pattern facing the liquid crystal panel, and a second prism pattern with a second refractive index higher than the first refractive index, the pattern facing the light guide plate.

Liquid crystal display device including back light having improved light concentration efficiency

A backlight unit for a liquid crystal display panel includes a diffusor that diffuses light emitted from a front surface thereof, a reflective plate that reflects light toward a rear surface of the diffusor; and a collimator that collimates the light emitted from the front surface of the diffusor toward the liquid crystal display panel. The collimator includes a base layer that refracts the diffused light from the diffusor toward the liquid crystal panel, a collimating layer of lenses disposed along two perpendicular directions on a front surface of the base layer, and a reflective pattern on a rear surface of the base layer along a boundary of each of the lenses, the reflective pattern exposing an aperture portion of the base layer facing each of the lenses.
