The present invention provides a liquid crystal display device having a backlight structural body which ensures dilating of an inverter circuit by adopting an electrolytic capacitor having temperature lifetime characteristic in an inverter circuit. The backlight structural body which is mounted on a back surface of the liquid crystal display panel includes a plurality of external electrode fluorescent lamps which is arranged in parallel on a surface of the back surface plate on which the liquid crystal display panel is mounted, a pair of power supply terminals which electrically connects the external electrode fluorescent lamps in parallel, an inverter printed circuit board which controls the external electrode fluorescent lamps, and power supply cables which connect the power supply terminals and the inverter printed circuit board, and the inverter printed circuit board is arranged on a lower side portion of a back surface of the back surface plate on a side opposite to a surface of the back surface plate on which the liquid crystal display panel is mounted. Due to such a constitution, an electrolytic capacitor which is mounted on the inverter printed circuit board is hardly influenced by the heat convention in the inside of the backlight structural body and hence, it is possible to largely enhance the temperature lifetime characteristic of the electrolytic capacitor.
