A light emitting display device is provided to represent the same grayscale on the same data voltage by reducing a swing range difference of data voltages using light emitting efficiencies according to colors. A light emitting display device includes a light emitting element(OLED), a first switching element, a transistor(M6), and first and second storage elements(C1,C2). The first switching element delivers a data signal from data lines in response to a first selection signal from scan lines. The transistor, which is diode-connected while the data signal is delivered, supplies a driving current to the light emitting element. The first storage element stores a first voltage from the first switching element corresponding to the data voltage. The second storage element, which is connected between the first scan line and a control electrode of the transistor, converts the first voltage to a second voltage through the first storage element when the first selection signal is changed from a first level to a second level.
