The present invention concerns lighting systems and particularly active lighting systems which are capable of providing automated changing lighting effects. These polynucleotides comprise nucleic acid sequences isolated from cDNA library from human ovary. The dipolar illumination mode of the first exposure is used to image mask features parallel to a first direction, and the dipolar illumination mode of the second exposure is used to image mask features perpendicular to the first direction. A plurality of storage capacitor conductors overlapping the storage wire to form storage capacitance are formed on the gate insulating layer.
