FIELD: images forming devices.
SUBSTANCE: invention relates to the field of liquid crystal displays. Technical result is achieved by first transistor having a gate and a drain connected to a high-voltage direct current; a second transistor having a gate connected to the source of the first transistor, a drain connected to a high-voltage direct current, and a source connected to the first common point; a third transistor having a gate connected to the point of the gate signal of the N-th level, a drain connected to the source of the first transistor and a source connected to the first low voltage direct current; a fourth transistor having a gate connected to the point of the gate signal of the N-th level and a drain connected to the common point; a fifth transistor having a gate connected to a point of the gate signal of the N-th level, and the drain connected to the common point; a sixth transistor having a gate connected to the source of the fourth transistor, a drain connected to the source of the fifth transistor, and a source connected to the third low voltage direct current.
EFFECT: technical result is to increase the efficiency of the scan bus for each point in the circuit.
