A liquid crystal display device includes: a bottom frame having a bent portion at an edge thereof; a light guide plate over the bottom frame, the light guide plate spaced apart from the bent portion by a gap; a light emitting diode (LED) assembly facing a side of the light guide plate, the LED assembly fixed to the bent portion; a main frame having a rectangular band shape over the bottom frame, the main frame having a rib corresponding to the gap; a liquid crystal panel over the light guide plate; and a top frame surrounding a front boundary portion of the liquid crystal panel, the top frame combined with the bottom frame and the main frame.
摘要:
Disclosed is a liquid crystal display (LCD) device having a good heat radiating function. Surface areas of a lower cover, an upper cover, and a guide panel are increased by forming grooves at the lower cover, the upper cover, and the guide panel. Heat generated from an optical source is rapidly radiated through the lower cover, the upper cover, and the guide panel having increased surface areas. This may prevent temperature increment of a backlight unit.

Provided is a lens driving unit for an optical pickup and an optical disc drive employing the lens driving unit. First and second driving coils are directly wound around a coil winding unit included in the lens frame, which is different from a conventional lens frame in which a driving coil is manufactured as a separate element and is separately attached to a lens frame.
