DISPLAY SYSTEM FOR WORK MACHINE

There is provided a system that enables a user, who is remote from a work machine, to recognize a situation around the work machine even when communication between a slave control device mounted in the work machine and a master control device is interrupted. An image of a work attachment (240) (operation mechanism) of a work machine (200) and the periphery of the work attachment, which corresponds to captured image data acquired by an imaging device (11), is displayed on an image output device (130) by means of a first communication mode established between a slave control device (110) mounted in the work machine (200) and a master control device (120). When the first communication mode is interrupted, instead of the image of the operation mechanism of the work machine and the periphery of the operation mechanism, a point cloud image corresponding to distance image data acquired by a distance sensor (12) is displayed on the image output device (130) by means of a second communication mode established between the slave control device (110) and the master control device (120).
