A backlight unit and a display device including the backlight unit are provided. A backlight unit includes a substrate, light sources disposed on one surface of the substrate, a first reflective film disposed on one surface of the substrate and including first openings, each of the first openings of the first reflective film exposing each of the light sources, and wavelength filter layers disposed above the first reflective film and disposed to correspond to the first openings, the wavelength filter layers are spaced apart from each other, and each of the wavelength filter layers covers at least one of the first openings.

Backlight unit and display device including the same

A backlight unit includes a light source array including at least one light source which emits light and a circuit board on which the light source is disposed, and a first optical layer disposed on the light source array. The first optical layer includes a first layer which defines at least one concave portion in a bottom of the first layer, where the at least one concave portion is coupled to the light source, a second layer disposed on the first layer, the second layer guiding light incident from the first layer in one direction, a plurality of optical patterns disposed on one surface of the second layer, the plurality of optical patterns selectively emitting light passing through the one surface, and a reflective layer disposed on the bottom of the first layer.

Backlight unit and display device having the same

An optical member and a display device, the optical member including a light guide plate; a low refractive index layer disposed on a top surface of the light guide plate; a first optical pattern layer disposed on a bottom surface of the light guide plate; and a second optical pattern layer disposed to cover a light-incident surface of the light guide plate. The second optical pattern layer includes a focusing lens structure.

Optical member and display device including the same

A backlight unit and a display device including the same are provided. The backlight unit includes a light source; a mold frame configured to accommodate the light source and having a window frame shape with an opening therein; and a supporting member disposed on the mold frame and comprising an optical pattern, wherein the mold frame comprises a first sidewall, and an inclined surface protruding obliquely downward and inward from an inner side surface of the first sidewall, and wherein the supporting member is disposed on the inclined surface of the mold frame.

Provided is a LED light source package comprising a circuit board, a light source seated on an upper portion of the circuit board, and a lens structure arranged on the upper portion of the circuit board via the light source. A surface that faces the light source in the lens structure includes a first inclined surface that projects toward the light source as going to a center portion of the lens structure.

LED light source package

Reflection plate, backlight unit and liquid crystal display are provided. In one aspect, there is provided a reflection plate comprising a bottom portion and a side wall portion that extends from circumferences of the bottom portion, wherein an upper surface of the bottom portion includes a diffusion reflection surface and an inner surface of the side wall portion includes a mirror reflection surface.

Reflection plate, backlight unit, and liquid crystal display including the same

Provided are a light emitting diode package and a backlight assembly including the light emitting diode package. The light emitting diode package may comprise a package main body including a cavity; a light emitting diode (LED) chip positioned in the cavity; a lead frame installed in the package main body, positioned in the cavity at least partly, electrically connected to the light emitting diode chip mounted on the lead frame, and having one surface having a diffusion reflective layer thereon.
