PROBLEM TO BE SOLVED: To provide a low cost TFT display device capable of suppressing the dynamic variation in a gate-off voltage and suppressing block unevenness. SOLUTION: The TFT display device is equipped with two or more gate driving modules 22 for controlling voltage supply timing for each of gate lines 11 on a TFT substrate 10 and a display control board 40 for supplying the gate-off voltage to the gate driving modules 22. The gate-off voltage is transmitted from the display control substrate 40 through a gate power source supply line 41 on the TFT substrate 10 to the gate driving modules 22. The display control substrate 40 has a gate-off power source circuit 213 generating the gate-off voltage and a resistance element 70 consisting of the resistance value higher than the wiring resistance of the gate power source supply line 41 up to the gate driving modules 22 nearest to the display control board 40. The gate-off voltage is supplied through the resistance element 70 to the gate power source supply line 41. COPYRIGHT: (C)2005,JPO&NCIPI |
