Abstract
A liquid crystal display device can readily achieve uniformization of the threshold voltages of individual thin film transistors in spite of its simple construction. The liquid crystal display device includes gate signal lines juxtaposed in one direction, drain signal lines juxtaposed to intersect with the gate signal lines, thin film transistors which are respectively formed in areas each surrounded by the gate signal lines and the drain signal lines and are driven by supply of scanning signals from the gate signal lines, pixel electrodes to which video signals from the drain signal lines are to be supplied via the respective thin film transistors, a first terminal for applying voltages to the respective gate signal lines via diodes, and a second terminal for applying voltages to the respective drain signal lines via diodes.
