Abstract
A projection device including a lens module and an actuating module is provided. The lens module includes at least one lens and is used for transferring an image beam. The actuating module is disposed beside the lens module, and is relatively close to the at least one lens. The actuating module includes a frame, a transparent element and at least one actuator. The transparent element is fixed on the frame. The actuator is disposed on at least one side edge of the frame, and is connected to the frame. In a light emission direction of the lens module, an orthographic projection of the actuator on a first reference plane does not overlap with an orthographic projection of the at least one lens on the first reference plane.
