An active matrix display panel has (1) a plurality of row electrode lines; (2) a plurality of column electrode lines; (3) a first MOS transistor for each pixel; and (4) a second MOS transistor for each pixel. The first MOS transistor has (a) a first terminal connected to each of the column electrode line, (b) a second terminal connected to a liquid crystal, (c) a control terminal connected to each of the row electrode line, wherein an ON potential is higher than a signal potential supplied to the row electrode line. The second MOS transistor has (a) a first terminal connected to each of the row electrode line, (b) a second terminal connected to the electro-optic element, and (c) a control terminal connected to the column electrode line, wherein an ON potential is higher than a signal potential supplied to the column electrode line.
