A display control device is provided to realize a bypass function of a display controller by using fewer chip select signal lines without causing a malfunction. In the display control device, bypassing a display controller is realized by using one chip select signal line and one signal line for the general ports provided to a host. Therefore, bypassing the display controller can be realized by using fewer chip select signal lines. In addition, malfunctioning is prevented when a bypass mode is provided because the switching to/from the bypass mode and the transmission of the CS signal are not performed by one common chip select signal line.
