ABSTRACT:
A driving circuit of a liquid crystal display device including a first insulating substrate on which a plurality of signal lines and a plurality of scan lines are disposed, and pixel transistors made of thin film transistors are disposed in matrix at intersection points of those lines; a second insulating substrate opposite to the first insulating substrate; and a liquid crystal held between the first and second insulating substrates, in which the driving circuit is disposed on the first insulating substrate; each of clock lines or base portions of the clock lines for supplying clock signals to the driving circuit is made of a two-layer structure of the same wiring material as a gate electrode of the thin film transistor and the same wiring material as a source electrode or drain electrode of the thin film transistor; and a wiring line crossing the clock lines or the base portions of the clock lines is made of a wiring line in the same layer as a black matrix covering the pixel transistors.
