Abstract
In an active matrix-type display device where scan bus lines (S.sub.i) and data bus lines (D.sub.j) are formed on different substrates, two kinds of scan bus lines (SP.sub.i, SN.sub.i) are provided. A first switching element (TFTN.sub.ij) is connected between a reference voltage supply line (V.sub.R) and a display electrode (E.sub.ij), and is controlled by a first scan bus line (SN.sub.i), and a second switching element (TFTP.sub.ij) is connected between the reference voltage supply bus line (V.sub.R) and the display electrode, and is controlled by a second scan bus line (SP.sub.i). The first switching element (TFTN.sub.ij) is turned ON by a positive or negative potential at the first scan bus line.
