Liquid crystal display apparatus, semiconductor devices, and manufacturing methods therefor

摘要

The invention relates to a bright image liquid crystal display apparatus, a semiconductor device and a manufacturing method therefor. The apparatus comprises gate lines (GL) formed on a substrate (SUB1) and an insulating film formed on the substrate, data lines (DL) formed so as to cross the gate lines, thin film transistors (TFTs) formed at the respective intersections of the gate lines with the data lines, and pixel electrodes (IT01) connected to the TFTs, wherein the central portion of the pixel electrodes is in contact with the substrate (SUB1) or the insulating film, and the peripheral portion of the pixel electrode is in contact with an insulating film which was the same layer as the gate insulating film (GI) of the (TFT). The end portion of the gate electrode of the TFT is tapered with a taper angle equal to or less than three times the taper angle at the end portion of the semiconductor pattern.
