A gradation display apparatus includes: a plurality of pixels, each including a light emitting element, a driving transistor, and a storage capacitor; a data line; a reference voltage line; and a control circuit. During a one frame period, the control circuit supplies a data voltage to each of the pixels through the data line, to write the data voltage in the storage capacitor, and, thereafter, supplies to the reference voltage line respectively different first and second voltages successively in this order or reversed order, so that, in each of the pixels, a sum of a light emitting quantity of the light emitting element during a period of supplying the first voltage and a light emitting quantity of the light emitting element during a period of supplying the second voltage equals to a predetermined light emitting quantity of the light emitting element predetermined according to image data.
