Abstract
Dummy holesare made for every one of display dotandat pixelsthrough interlayer filmup to gate electrode and scanning linesbefore interlayer filmon glass substrateis washed. When interlayer filmis washed, electric charges stored at semiconductor layerare substantially the same in quantity as those stored at gate electrode and scanning linesthrough dummy holes. Thus, electric potentials at gate electrode and scanning linesare substantially equal in magnitude to those at semiconductor layer. This can suppress the occurrence of voltage differences imposed between gate electrode and scanning linesand semiconductor layer
