Abstract:
1. A method for fabricating a thin film transistor substrate comprising the steps of: forming a thin film transistor on a substrate; forming a protective film on the thin film transistor and the substrate, the protective film covering over a step of the thin film transistor and having a first flat surface and a plurality of first projections extending upwardly from the first flat surface and spaced from each other, the plurality of first projections each having a rectangular cross section; forming a pixel electrode on only a portion of the protective film such that the pixel electrode can maintain the same profile as a top profile of the protective film; and forming a non-electrically conductive alignment film having a second flat surface and a plurality of second projections extending upwardly from the second flat surface and spaced from each other in the alignment film in same step, the alignment film being formed on and in direct contact with both the protective film and the pixel electrode so that the alignment film can maintain the same profile jointly defined by the top profile of the protective film and the profile of the pixel electrode.
