    • An LCD is provided to enhance the grounding structure of a flexible circuit board, thereby reducing EMI(Electro-Magnetic Interference) degree generated in the flexible circuit board, by directly connecting a ground wiring of the flexible circuit board to a bottom chassis. An LCD panel(10) has electrode pads. A light source(51) applies light toward a rear surface of the LCD panel. A bottom chassis(90) contains the light source. A driving part(20) is connected to the electrode pads, and applies driving signals to the LCD panel. A driving circuit controls the driving part. The driving circuit includes a first driving circuit board(31) connected to the driving part and positioned at one lateral surface of the bottom chassis, and a second driving circuit board(33) connected to the first driving circuit board and positioned at a rear surface of the bottom chassis. A flexible circuit board(100) connects the first and second driving circuit boards to each other, and has a ground wiring electrically connected to the bottom chassis.
