1. A display apparatus comprising on a substrate:

  • a plurality of scanning lines;

    a plurality of data lines extending in a direction intersecting the extension direction of the scanning lines;

    a plurality of common power-feed lines parallel to the data lines; and

    pixels formed in a matrix by said data lines and said scanning lines, each of the pixels comprising;

    a first thin-film transistor in which a scanning signal is supplied to its first gate electrode via said scanning lines;

    a holding capacitor for holding an image signal supplied from said data lines via the first thin-film transistor; and

    a second thin-film transistor in which said image signal held by the holding capacitor is supplied to its second gate electrode; and

    a light-emission element having an organic semiconductor film, which emits light by a driving current that flows between a pixel electrode and a counter electrode when said pixel electrode is electrically connected to said common power-feed lines via said second thin-film transistor in a section between layers of said pixel electrode formed for each of said pixels and said counter electrode opposing the pixel electrode, wherein pixels in which said driving current is passed in the section between the pixels and the common power-feed line are arranged on both sides of said common power-feed line, and said data lines pass on a side opposite to said common power-feed line with respect to the pixels.
