Liquid crystal display device
Provided is a liquid crystal display device. The liquid crystal display device includes a guide frame, a plurality of light sources disposed on the guide frame, a diffusion member disposed above the plurality of light sources as being spaced away from the plurality of light sources, and a plurality of wires disposed between the plurality of light sources and the diffusion member. The liquid crystal display device according to an exemplary embodiment of the present disclosure uses the diffusion member having a smaller thickness than a related art diffusion plate. Thus, it is possible to reduce the overall thickness of the liquid crystal display device. Further, it is possible to support the diffusion member with the plurality of wires.
1. A liquid crystal display device comprising:
a guide frame;
a plurality of light sources on the guide frame;
a diffusion member above and spaced away from the plurality of light sources, configured to diffuse light emitted from the plurality of light sources, and formed of a fiber material;
a plurality of optical sheets on the diffusion member; and
a plurality of wires in contact with the diffusion member so as to support the diffusion member and the plurality of optical sheets and fixed to the guide frame,
wherein the plurality of wires includes a plurality of first wires and a plurality of second wires disposed to intersect with each other so as to form a mesh pattern,
wherein the plurality of first wires has first portions on the plurality of second wires and second portions under the plurality of second wires in an area where the plurality of first wires intersect with the plurality of second wires, and the first portions and the second portions are located alternately, and
wherein the plurality of wires is formed of fluorocarbon.
2. The liquid crystal display device according to claim 1 ,
wherein the thickness of the diffusion member is between 0.1 to 30 μm, and
wherein the plurality of wires has a thickness of 0.5 mm or less.
3. The device of claim 2 , wherein said diffusion member contains birefringent microfibers configured to reduce mura phenomenon.
4. The device of claim 3 , wherein said birefringent microfibers are made of one or more materials among polyester, polyurethane, polymethyl methacrylate (PMMA), and nylon.
5. The device of claim 1 , wherein said mesh-like mesh pattern is configured to have certain dimensions in accordance with the size, shape and weight of said functional film.
6. The device of claim 5 , wherein said wires are configured to have a relatively high refractive index to provide additional light diffusion.
7. The device of claim 6 , wherein said light sources are configured as direct-type light emitting diodes.
