Liquid crystal display device and fabricating method thereof
View Patent ↗A liquid crystal display device that reduces manufacturing cost, contributes to a thin profile, and generates uniform brightness, and a fabricating method thereof are disclosed. In the liquid crystal display device, a liquid crystal display panel is prepared. A backlight includes a plurality of lamps, a diffusion plate which is located on the lamps, and an intermediate diffusion medium located between the lamps and the diffusion plate to diffuse light from the lamps, and irradiates light to the liquid crystal display panel. Furthermore, in the method of fabricating the liquid crystal display device, a diffusion material is molded using a mold to form an intermediate diffusion medium that includes a plurality of ribs connected to an external band of square type and both sides of the external band of square type, respectively. The intermediate diffusion medium is located between lamps and a diffusion plate.
1. A liquid crystal display device, comprising:
a liquid crystal display panel; and
a backlight including a plurality of lamps, a diffusion plate which is located on the lamps, and an intermediate diffusion medium located between the lamps and the diffusion plate to diffuse light from the lamps, and irradiating light to the liquid crystal display panel,
wherein the intermediate diffusion medium includes a first ribs corresponding with a diffusion area overlapped with the lamps and a second ribs corresponding with a transmission area not overlapping with the lamps,
wherein the first ribs and the second ribs are connected to an external band of square type that is formed along the circumference of the edges of the first and second ribs,
wherein the transmission area includes an open area and a second ribs, and
wherein the length of the open area is more than the length of the second rib.
2. The liquid crystal display device according to claim 1 , further includes:
a bottom cover receiving the lamps to an internal space and having an aperture part which is covered by the diffusion plate.
