A self-luminous display device is provided to display a correct inversion image by replacing a white signal level with a black signal level according to the polarity of a video signal. A self-luminous display device includes a display panel(10), a video signal processing circuit, a polarity changing circuit(28), a first DAC(29), a second DAC(30), and a third DAC(Digital to Analog Converter)(31). The video signal processing circuit includes a serial/parallel converter(21), an RGB matrix(22), a selector circuit(23), a color compensation circuit(24), a contrast/brightness adjusting circuit(25), a gamma correction circuit(26), and an ACL(Auto Color Limit) circuit(27). The polarity changing circuit changes the polarity of a digital video signal. The first DAC converts the RGB video signal from the polarity changing circuit to a digital signal. The second DAC converts high-level reference data from the polarity changing circuit to a digital signal. The third DAC converts low-level reference data from the polarity changing circuit to a digital signal.
