are inputted to the first gate driver substrate 3 through the flexible cable 6 from the signal process substrate 27 these driver control signals are supplied to the gate drivers 18 to 21 thus each of the gate drivers 18 to 21 drives the signal line of the left half in the x axis direction it should be noted that the number of gate drivers mounted on the first gate driver substrate 3 is not limited to 4 it may be an arbitrary number the second gate driver substrate 4 loads with four gate drivers 22 to 25 the gate rivers 22 to 25 are constituted by the tcp the driver control signals are inputted to the second gate driver substrate 4 through the flexible cable 5 the wiring pattern 200 on the source driver substrate 2 and the flexible cable 7 from the signal process substrate 27 these driver control signals are supplied to the gate drivers 22 to 25 thus each of the gate drivers 22 to 25 drives the signal line of the right half in the x axis direction also it should be noted that the number of gate drivers mounted on the second gate driver substrate 4 is not limited to 4 it may be an arbitrary number the backlight unit 26 generates a light and irradiates.
