A stacked display driver integrated circuit (DDIC) configured to drive a display panel of a display device includes a first circuit and a second circuit. The first circuit is formed by a low-end process according to a first design rule such that the first circuit has a first critical dimension. The second circuit is formed by a high-end process according to a second design rule smaller than the first design rule such that the second circuit has a second critical dimension smaller than the first critical dimension. The first circuit and the second circuit are stacked in a vertical direction. The size of the stacked DDIC may be reduced by stacking, in the vertical direction, the first circuit including analog circuits and the second circuit including digital circuits.
