Abstract
A plurality of cascade-connected register circuits which comprises a bidirectional shift register include a top register circuit, a bottom register circuit, and main register circuits. The register circuit has an output circuit which outputs one of four-phase clock pulses when a voltage of a first node is an active level; a second output circuit which outputs a non-active level when a voltage of a second node is the active level; a second node reset circuit which sets the second node to the non-active level when a voltage of a second node reset terminal is the active level. The forward scan signal sets the voltage of the first node of the top register circuit to the active level, and the forward scan signal sets the voltage of the second node reset terminal of the bottom register circuit to the active level.
