The present invention discloses a liquid crystal display (LCD) device, which includes a display panel, a back light module, a flexible printed circuit board, and a chip. The back light module includes a back cover. The back cover has a protrusion facing the display panel, and the back cover has a recess corresponding to the protrusion on a bottom surface of the back cover. The flexible printed circuit board is electrically coupled to one side of the display panel, and bent to the bottom surface of the back cover. The chip is fixed on the flexible printed circuit board and located at the recess of the back cover, so that the chip is positioned away from the light source located beside the light guide plate, thereby overcoming an overheating problem of the chip in a narrow bezel LCD.
