Abstract:
1. A liquid crystal display module, comprising: a liquid crystal display panel; a backlight unit including at least one light emitting diode; a bottom frame surrounding the backlight unit, the bottom frame comprising a printed circuit board and the at least one light emitting diode disposed on the printed circuit board; a backlight driving circuit on an outer surface of the bottom frame and electrically connected to the at least one light emitting diode, wherein the bottom frame is formed of a metal core printed circuit board including: a metal core layer electrically insulated from the at least one light emitting diode; a first insulating layer on a first surface of the metal core layer; a first conductive line on the first insulating layer and electrically connected to the at least one light emitting diode; a second insulating layer on a second surface of the metal core layer; and a second conductive line on the second insulating layer and electrically connected to the backlight driving circuit, and wherein the metal core layer has at least one contact hole penetrating the metal core layer, and the first and second insulating layers are formed on an inner surface of the at least one contact hole; a main frame surrounding the liquid crystal display panel; and a top frame surrounding a front edge of the liquid crystal display panel and is combined with the bottom frame through the main frame.
