WORK MACHINE

A hydraulic excavator includes a controller having an actuator control section that executes machine control of operating a work implement in accordance with a predetermined condition in a case in which a work implement is positioned in a deceleration area, and that does not execute machine control in a case in which the work implement is positioned in a non-deceleration area. The controller further includes an operation deciding section that decides operation of the work implement on the basis of an operation amount of an operation device, and a display control section that displays, on a display device, a positional relationship among the work implement, a target surface and a boundary line between the deceleration area and the non-deceleration area. The actuator control section executes machine control while changing the position of the boundary line depending on a result of the decision by the operation deciding section, and the display control section changes the display position of the boundary line on the display device, depending on the result of the decision by the operation deciding section.
