A liquid crystal display device converts input signals into liquid crystal drive signals so as to display an image on a liquid crystal panel. A plurality of flexible boards are connected to the liquid crystal panel, each of the flexible boards having a drive IC which converts the input signals into the liquid crystal drive signals. A connection board is connected to the liquid crystal panel so as to supply the input signals to first input lines formed on the liquid crystal panel. Each of the flexible boards has second input signal lines for supplying the input signals to the drive IC; a first end of each of the second input signal lines is connected to a respective one of a first group of the first input signal lines. A second end of each of the second input signal lines is connected to a respective one of a second group of the first input signal lines which are formed in positions different from positions where the first ends of the second input lines are connected to the first group of the first input lines.
