A transfer plate wetting system and an alignment liquid transfer system are provided. The transfer plate wetting system includes a first plate wetting device. The first plate wetting device includes an alignment agent storage tank (7), an alignment agent solvent storage tank (8), a nozzle (10) and a pipeline connector (T) configured for communicating the alignment agent storage tank (7), the alignment agent solvent storage tank (8) and the nozzle (10). The nozzle (10) is configured to spray out alignment liquid including an alignment agent and an alignment agent solvent. The transfer plate wetting system is capable of forming alignment layer with uniform thickness, thus improving display effect of display device.
