Abstract: PROBLEM TO BE SOLVED: To attain cost reduction by realization of a COG(chip on glass) and a WOA(wiring on array) by reducing the number of inputs of LCD(liquid crystal display) drivers. SOLUTION: The COG and the WOA are realized by reducing wirings to respective source divers IC 20 as much as possible while cascading the source drivers IC 20 to which the video signal inputted through a video I/F(interface) 3 is distributed in a liquid crystal display device. That is, this device is provided with a liquid crystal cell 2 forming a picture display area and a source driver 7 applying voltages to the liquid crystal cell 2 based on the video signal inputted through the video I/F 3 on a substrate and the driver 7 has plural source drivers IC 20 which are mounted on the same substrate on which the cell 2 is mounted and, also, which are cascaded by using signal lines.
