ABSTRACT:
A liquid crystal display and its producing method which prevents induction of electrons in a back channel part of a TFT by a positive voltage applied to an opposite electrode formed on a color filter substrate so as to reduce a leakage current in off of the transistor. A TFT substrate and the color film substrate are bonded together via a liquid crystal interposed therebetween. On the TFT substrate, a pixel electrode and the TFT including a gate electrode, a gate insulating film, an a-Si film, an n+ a-Si film, a drain electrode and a source electrode are formed. On the color filter substrate, a color filter and the opposite electrode are formed and an opening is further formed in a part facing to the TFT in the opposite electrode.
