A liquid discharge device is provided with a head, a cover member, a negative pressure source, a seal member, and a controller. The head has a nozzle plane in which a nozzle is formed. The cover member has a fluid passage and is capable of covering the nozzle plane such that one end of the fluid passage is in communication with the nozzle. The negative pressure source is connected to the fluid passage. The seal member has a non-nozzle plane in which the nozzle is not formed. The non-nozzle plane is capable of sealing the one end of the fluid passage. The controller drives the negative pressure source in a first state in which the cover member is covering the nozzle plane. The controller drives the negative pressure source in a second state in which the non-nozzle plane is sealing the one end of the fluid passage.
