PROBLEM TO BE SOLVED: To provide a display device capable of deciding a correct OEM destination, even when an analog input voltage value becomes unstable at the establishing of an OEM destination, based on an analog input voltage value to a microcomputer. SOLUTION: In a display device which is made so as to establish an OEM' destination, based on an analog input voltage value to be inputted to a controller and to change over one part of a software processing according to the decided OEM destination, this device is provided with a means which decides an OEM destination based on an analog input voltage value, when the value is stable. Also it stores the OEM destination in a nonvolatile memory at the performing the establishing processing of the OEM destination and a means which decides an OEM destination based on OEM destination data stored in the nonvolatile memory, when the value is unstable at the time of performing the deciding processing of the OEM destination.
