A liquid crystal display (LCD) comprising an LCD panel on which an electrode pad is provided; a driving part connected to the electrode pad and applying a driving signal to the LCD panel; a light source part providing light to a rear surface of the LCD panel; and a circuit board comprising a driving circuit part applying a driving control signal to the driving part and an inverter providing a light source driving voltage to the light source part. Accordingly, the LCD may improve work efficiency in a modular assembly process and decrease voltage overload of a voltage converter.
