The present invention relates to a reflection plate for a backlight unit in a liquid crystal display device, and more particularly, to a reflection plate for a backlight unit in a liquid crystal display device, which is made of a thermoplastic thermal conductive resin composition having a thermal conductivity of at least 0.35 W/mK, thereby effectively solving the thermal problem of the backlight unit, and having excellent properties such as shock resistance, heat resistance, mechanical strength, and the like, as well as having excellent reflectivity, thereby improving the durability of the liquid crystal display device. Furthermore, the present invention relates to a backlight unit of a liquid crystal display device, comprising a reflection plate positioned at a lower portion of a lamp of the backlight unit for reflecting the light coming out of the lamp, a supporting rod for the lamp, and a lower plate functioning as a heat sink, wherein the reflection plate and the lower plate are made of the same material, thereby effectively solving the thermal problem of the backlight unit, and simplifying the manufacturing process.

Reflection plate for backlight unit and backlight unit of liquid crystal display having good thermal conductivity

Provided is a wholly aromatic liquid crystalline polyester resin compound. The wholly aromatic liquid crystalline polyester resin compound includes a wholly aromatic liquid crystalline polyester resin having a high melting point and mica having a predetermined size.

Wholly aromatic liquid crystalline polyester resin compound having improved fluidity

Provided is a wholly aromatic liquid crystalline polyester resin compound having excellent electrical insulating properties, heat resistance, and mechanical strength due to the inclusion of an inorganic filler having low electrical conductivity, high heat resistance, and high mechanical strength.

Wholly aromatic liquid crystal polyester resin compound having improved insulation properties

Disclosed are a wholly aromatic liquid crystal polyester resin compound and a preparation method thereof. The disclosed wholly aromatic liquid crystal polyester resin compound comprises a wholly aromatic liquid crystal polyester resin having a high melting point, and an inorganic filler having a high thermal conductivity. In addition, the disclosed wholly aromatic liquid crystal polyester resin compound can be prepared by using a twin screw extruder having a barrel temperature of 350 to 450&#xb0; C.
