1. A method of display on a display apparatus including a display unit in which a plurality of light-emitting elements emitting light corresponding to flowing current are arranged, the plurality of light-emitting elements including light-emitting elements of different colors each of which emits light at the maximum luminance to display white, wherein electric current densities per unit light-emitting area of the light-emitting elements of different colors to display white are mutually different, the method comprising:

  • providing electric current to a first light-emitting element group which includes the light-emitting elements of the different colors and forms a character or a graphic in a certain position in the display unit; and

    providing electric current to a second light-emitting element group which includes the light-emitting elements of the different colors same as the first light-emitting element group and forms a background of the character or the graphic in a position surrounding the first light-emitting element group;

    wherein, during providing of electric current to the first and second light-emitting groups to form the character or the graphic and the background, respectively, a ratio for the light-emitting elements of the color having the largest electric current density to display white is closer to 1 than a ratio for light-emitting elements of the other colors, with respect to the ratio of the electric current flowing through the light-emitting elements in the second light-emitting element group to the electric current flowing through the light-emitting elements in the first light-emitting element group.
