Abstract: The present disclosure provides a vacuum ring for removing bubbles of a laminated assembly and a method for bonding the laminated assembly using the same. The vacuum ring includes an indented portion receiving a laminated assembly to be sealed, and an inner space of the indented portion is in communication with a vacuum source to remove the bubbles. The vacuum ring also includes projection members that are projected inside on the bottom of the indented portion at positions where the projection members are spaced upward from a lower end of the indented portion to receive the laminated assembly, and the projections members are spaced downward from the upper end of the indented portion. Further, the laminated assembly is produced by using the vacuum ring to achieve effective exhaustion by using an aperture formed between side ends of the projection members and the bonding cover.
