1. display device has:

  • sweep trace, and data line, supply lines, pixel, described display device are characterised in that to have on the described pixel;

    sweep signal supplies to the 1st thin film transistor (TFT) of grid via described sweep trace;

    By described the 1st thin film transistor (TFT), keep the electric capacity of keeping of the picture signal supplied with by described data line;

    Apply with by described the 2nd thin film transistor (TFT) of keeping the suitable current potential of described picture signal that electric capacity keeps;

    And the light-emitting component that possesses light-emitting film, when the pixel electrode that described light-emitting film forms on by described pixel is electrically connected to described supply lines by described the 2nd thin film transistor (TFT), undertaken luminous by the drive current that between described pixel electrode and opposite electrode, flows through;

    Described the 1st thin film transistor (TFT) constitutes with the thin film transistor (TFT) of described the 2nd thin film transistor (TFT) with mutually reciprocal conductivity type,Described light-emitting component is with the luminous current drive-type organic EL luminous element of direct current.
