A liquid crystal display device includes a liquid crystal display panel, a plurality of light sources for irradiating onto the liquid crystal display panel, at least two electrode boards at ends of each of the light sources for electrically connecting the light sources, an inverter board aligned parallel to the light sources for providing drive signals to the light sources through the electrode boards, and a first cover for accommodating the liquid crystal display panel, the light sources and the electrode boards on a first side thereof and for accommodating the inverter board on a second side thereof such that the inverter board is substantially on a same plane as a main portion of the cover.
