Abstract
In order to provide a liquid crystal display apparatus having bright image display and a preferred production yield, a gate insulating film under a transparent pixel electrode on a transparent substrate is provided with an aperture smaller than a plane area of the pixel electrode, and a source electrode pattern under the pixel electrode is composed so as to cross the aperture. Thin film transistors (TFT) of the liquid crystal display apparatus have a gate electrode and a laminate layer of a gate insulating film and a semiconductor film. End portions of the gate electrode and the laminate layer are tapered, and the end portion of the gate electrode is tapered with a taper angle equal to or less than three times (where, less than 90.degree.) of a taper angle at the end portion of the laminate layer.
