A display driver integrated circuit and a method of manufacturing the same are provided. The method of manufacturing a display driver integrated circuit (DDI) including a first area, a second area, and an overlapping area in which the first area and the second area overlap each other includes forming a first pattern in the first area using a first reticle; and forming a second pattern in the second area using a second reticle, and ends of the first pattern and the second pattern are connected within the overlapping area and the first area and the second area are asymmetrically set based on the overlapping area such that the overlapping area includes only a metal line.
