Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal display with reduced noise by controlling the capacitance of a capacitor in a current controller to ≤100 nF and the frequency of a common voltage to out of an audio frequency range. SOLUTION: The liquid crystal includes a first display panel unit; a second display panel unit; a first FPC (flexible printed circuit film) having an opening exposing the second display panel unit; a light source unit including a plurality of lamps and supplying light to the first and second display panel units;, and a current controller controlling a current applied on the light source unit and including a capacitor, wherein the capacitance of the capacitor is specified to ≤100 nF.
