Patent ID: 7800394

Claim:
A display device comprising: a gate signal line; a source signal line; a driver circuit which outputs a signal to the gate signal line and which includes a shift register circuit ; a switch configured to connect the gate signal line to the shift register circuit; a pixel connected to the gate signal line and the source signal line, to which a signal is written from the source signal line when the gate signal line is selected; a wiring to which a signal for controlling the switch is inputted; and an inspecting circuit connected to the source signal line and the wiring, the inspecting circuit detecting whether a potential of the source signal line is a potential for making the pixel emit no light when the switch changes from being in an on state to being in an off state, wherein the driver circuit comprises a signal correcting circuit for correcting a timing to output a signal to the gate signal line in accordance with the detection by the inspecting circuit of whether the potential of the source signal line is the potential for making the pixel emit no light.
