A borderline (side edge) of the semiconductor layer (stripe) is positioned at the outside of a borderline (side edge) of the data line. In this way, by minimizing the overlap of the data line and the pixel electrode (so that a width of the data line is smaller than that of the semiconductor layer (stripe), parasitic capacitance is reduced, so that vertical line blur can be prevented.
