<P>PROBLEM TO BE SOLVED: To provide a display device that automatically changes target fuel economy corresponding to street mode and work mode, and appropriately displays fuel economy information for each operation mode on a fuel economy display unit. <P>SOLUTION: A multi-monitor (display device) 53 mounted on a self-propelling construction machine including a lower part traveling body and a work machine both having an engine as a power source, and receiving data of instantaneous fuel economy from a controller for controlling an amount of fuel to be supplied to the engine includes: a display unit 112 having an eco-gauge (fuel economy display unit) for displaying the fuel economy information in the street mode for actuating the lower part traveling body, and the fuel economy information in the work mode for actuating the work machine, a full-scale fuel economy calculating means 122 for calculating a fuel economy value when the eco-gauge is at a full-scale, on the basis of each target fuel economy in each mode, and a gauge display value calculating means 123 for calculating a ratio of the instantaneous fuel economy with respect to the full-scale fuel economy calculated by the full-scale fuel economy calculating means 122. <P>COPYRIGHT: (C)2013,JPO&INPIT |
