Abstract

A substrate for a display device wherein a plurality of row electrode lines and a plurality of column electrode lines are arranged in a matrix form on a substrate; pixel electrodes and pixel-drive-TFTs each having a polycrystalline semiconductor channel are provided so as to correspond to each intersection of the row electrode lines and the column electrode lines; the pixel-drive-TFTs are arranged in a line-like form in the direction of row electrode line; row signals are supplied through the row electrode lines to the pixel-drive-TFTs; and column signals are supplied through the column electrode lines to the pixel-drive-TFTs; a plurality of row driver circuits for supplying row signals are formed on the substrate so as to correspond to each of the row electrode lines; each of the row driver circuits has row-drive-TFTs; the row-drive-TFT has a polycrystalline semiconductor channel; and the row-drive-TFT is arranged in a line-like form in the direction of row electrode line with respect to the pixel-drive-TFTs for a single row electrode line.
