A liquid crystal display includes a liquid crystal display panel which has first and second drain lines groups, a control circuit board which has a control unit, a first and second drain drivers groups connected to the corresponding first and second drain lines groups, a back light unit, a metal frame, and a shield member which shields against EMI. Both of the first and second drain drivers groups are arranged at a same peripheral side of the liquid crystal display panel. The control unit supplies first and second signals to the drain drivers groups via flexible printed circuits which are connected to the control circuit board. The control circuit board is sandwiched between the metal frame and the shield member, and the metal frame is arranged between the control circuit board and the liquid crystal display panel.
