Abstract
A display device in which partial driving can be performed with a simplified configuration of a circuit including a wiring. One of signal processing circuits includes a first transistor that controls the potential of its respective gate signal line, and a second transistor that outputs a start signal for the subsequent stage and a reset signal for the preceding stage. A signal for controlling whether the gate signal line is in an active state (a state where a selection signal is output) or a non-active state (a state where a selection signal is not output or a non-selection signal continues to be output) is input to the first transistor. A clock signal is input to the second transistor. Thus, the number of wirings necessary for operating the device is reduced.
