Abstract
The utility model provides a back plate, a light-emitting diode (LED) back light module and an LED liquid crystal display device. The back plate comprises a back plate main body and nut columns. The nut columns are fixedly arranged on one edge of the back plate main body. The height values of the nut columns are larger than the thickness value of a liquid crystal panel source drive board of the LED liquid crystal display device. Installation holes of the liquid crystal panel source drive board are sleeved on the nut columns, and screws are in thread connection with the nut columns. The height values of the nut columns are larger than the thickness value of the liquid crystal panel source drive board so that a gap is reserved between the liquid crystal panel source drive board and the end faces of the screws, and the liquid crystal panel source drive board can move along the nut columns. When the liquid crystal display panel is jolted to drive a chip on film (COF) to move, the COF draws the liquid crystal panel source drive board to move along the nut columns, thereby preventing the COF from being damaged by drawing. Accordingly, the LED liquid crystal display device is prevented from being damaged, and the reliability of the LED liquid crystal display device is improved.
