Abstract:
A display apparatus displays a character or a graphic formed by a first light-emitting element group (first group) and a background of the character or the graphic formed by a second light-emitting element group (second group) on a display unit. The ratio of the electric current flowing through the light-emitting elements (elements) in the second group to the elements in the first group with respect to the elements of a same color as the elements whose electric current per unit light-emitting area is the largest among the elements of different colors when the display unit displays white, is closer to 1 than the ratio of the electric current flowing through each of the elements in the second group to the elements in the first group with respect to the elements of different colors from the elements whose electric current per unit light-emitting area is the largest when the display unit displays white.
