Abstract

The invention provides a liquid crystal display (LCD) device. The device comprises a backlight module, a gel frame, an LCD panel and a front frame, wherein the gel frame is arranged on the backlight module; the LCD panel is arranged on the gel frame; the front frame is arranged on the LCD panel; the backlight module comprises a back board, a lightbar and a graphite sheet; the lightbar is installed on the back board; the graphite sheet is arranged between the back board and the lightbar; the lightbar comprises an inverted U-shaped metal base printed circuit board (PCB) and a plurality of LED (light emitting diode) lamps installed on and electrically connected with the metal base PCB; and the metal base PCB is clamped on the back board and then the lightbar is installed on the back board. The LCD device has the following beneficial effects: the lightbar is clamped on the back board by the inverted U-shaped metal base PCB and the graphite sheet is arranged between the lightbar and the back board to conduct heat to the back board to dissipate heat, the difficulty in assembly or disassembly caused by adopting the method that the lightbar is pasted by heat dissipation gel or locked by a screw so as to be fixed is avoided, a simpler assembly or disassembly method is provided and the operation time is saved.
