摘要:
An protective film and a resin layer are stacked on an insulation substrate on which a TFT is formed, and after a contact hole is formed in the resin layer, the protective film below the contact hole is etched and removed. A pixel display electrode is allowed to contact a drain electrode at the area of the contact hole; thus, a liquid crystal display is formed. A cut-out section, which communicates with the lower layer is formed in the drain electrode in the area of the contact hole. Upon forming a TFT section island-shape semiconductor layer so as to provide a TFT, a hole section island-shape semiconductor layer is also formed in the area of the contact hole. With this arrangement, it is possible to provide a manufacturing method of a liquid crystal display which can avoid the occurrence of a step discontinuity in the pixel display electrode and the subsequent disconnection in the pixel display electrode.
