GATE SIGNAL LINE DRIVE CIRCUIT AND DISPLAY DEVICE

摘要

Provided is a gate signal line drive circuit including a shift register basic circuit for applying a high voltage for a signal high period and a low voltage for a signal low period to a gate signal line at the time of a screen display. The shift register basic circuit includes a gate line high voltage applying circuit applying a high voltage for the signal high period to the gate signal line, and a gate line low voltage applying circuit applying a low voltage to the gate signal line, wherein in the shift register basic circuit, the off-voltage is applied to the switch of the gate line low voltage applying circuit for a predetermined period at the time of a screen non-display.
