1. A display apparatus, comprising:

  • a current driving type light-emitting device provided for each pixel;

    a driving device provided for each of said pixels that controls a driving current flowing to said light-emitting device;

    a power source unit that supplies a power source voltage through a power wire to cause said driving current to flow to said light-emitting device via said driving device;

    a signal wire driving unit that supplies a data signal having a voltage to said driving device through a signal wire, said driving device controlling said driving current in accordance with the voltage with said data signal; and

    a voltage adjusting unit that adjusts at least one of said power source voltage of said power source unit and said data signal at said signal wire driving unit, in such a manner that, when a data signal of a predetermined voltage is supplied to said driving device through said signal wire, at least one of a quantity of driving current flowing and a quantity of light emitted by said light-emitting device comes close to a predetermined reference value.
