The present disclosure discloses a light emitting diode (LED) backlight driving circuit, a backlight module, and a liquid crystal display (LCD) device. The LED backlight driving circuit includes an LED lightbars. An output end of the LED lightbar is connected with a control integrated circuit (IC) in series, and is also connected with a shunt controllable switch. The shunt controllable switch is switched on when a voltage of the output end of the LED lightbar exceeds a preset value and is switched off when the voltage is less than the preset value. In the present disclosure, because a shunt controllable switch is connected in parallel in the control IC, when the LED lightbars are short-circuited, the shunt controllable switch is switched on, a part of current flows towards the shunt controllable switch, and the burden of the control IC is alleviated. Thus, the temperature of the control IC is reduced.
