Abstract
An active matrix panel includes a gate line connected to control electrodes of a plurality of transistors; and a drive circuit supplying the gate line with a conducting voltage and a non-conducting voltage. The drive circuit includes a shift register including a plurality of shift register unit circuits connected to each other, and a demultiplexer including a plurality of demultiplexer unit circuits into which output signals of the shift register unit circuits are input. The demultiplexer unit circuit includes a first transistor for supplying the gate line with the conducting voltage, and a second transistor for supplying the gate line with the non-conducting voltage. The first transistor is changed from a non-conducting state into a conducting state when the second transistor is in the conducting state.
