Abstract
A display control substrate and a method of manufacturing thereof, includes a thin film transistor (TFT) that is provided for each of a multiplicity of pixel sections provided in two dimensions and is an inversely staggered TFT. A gate electrode wiring, a Cs wiring and a source electrode wiring of the TFT are simultaneously formed. An interlayer insulation film is deposited after gate insulation films and semiconductor islands are formed. After contact holes are formed in the interlayer insulation film, at the time of forming a pixel electrode, a connecting portion for connecting cut portions of the source electrode wirings via the contact hole is formed. The source electrode wiring is connected to a source region of the semiconductor island by the connecting portion. This process reduces the number of masks required at the time of manufacturing a TFT substrate, and also reduces the lead time, increases the yield and reduces the manufacturing cost.
