The present invention discloses a method for fabricating a dam-free glued structure. Firstly, a multi-point piezoelectric spraying device is provided, and the multi-point piezoelectric spraying device stores a water glue. Then, at least one film-forming process is performed. In the film-forming process, the multi-point piezoelectric spraying device sprays multiple droplets formed of the water glue on a first plate at the same time, all of which do not touch each other before landing on the first plate, and each droplet does not have a long and narrow tail shape. After all the droplets land on the first plate, all the droplets spread and combine on the first plate to form an adhesive film with a smooth surface. Finally, the adhesive film is pre-cured. After the film-forming process, the adhesive film is formed between the first plate and a second plate. A main curing process is performed on the adhesive film, the first plate, and the second plate to fix the adhesive film between the first surface and the secon
