Liquid crystal display device

An LCD display device comprising:

• a backlight unit including a plurality of light emitting diodes which generate light, and emitting the light generated by the light emitting diodes to a liquid crystal panel;
• a main flexible circuit board on which driving circuits to drive the light emitting diodes and the liquid crystal panel;
• a sub-flexible circuit board on which the light emitting diodes are mounted, electrically connected to a wire pattern formed on the main flexible circuit board by being soldered to a side surface of the main flexible circuit board to electrically connect the light emitting diodes and the driving circuits for the light emitting diodes;
• and
• a support main encompassing the liquid crystal panel and the backlight unit and including a step portion at a side surface thereof to accommodate a soldering portion between the side surface of the main flexible circuit board and the sub-flexible circuit board which are connected by soldering.
