A liquid crystal display (LCD) includes an LCD panel, a backlight module, and a circuit board. The backlight module disposed under the LCD panel includes a back plate, a light emitting diode (LED) light source, a protrusion, and a light guide plate. The LED light source disposed in the back plate includes a substrate and LEDs. The protrusion and the LEDs are disposed on the substrate, and the protrusion has first power contacts. The light guide plate is disposed between the back plate and the LCD panel and has a light entering surface. A light emitting surface of each of the LEDs faces the light entering surface. The circuit board disposed under the back plate is electrically connected to the LCD panel. The circuit board has a circuit layout and second power contacts, and the second power contacts contact the first power contacts correspondingly.
