Method for joining plates, plate joining structure, and display module having the same

摘要

At least a portion of a first plate and at least a portion of a second plate are arranged to have an overlapping portion, a first deformation unit is formed at the overlapped portion, and a second deformation unit is formed in the first deformation unit. The first deformation unit and the second deformation unit protrude in opposite directions from each other, and the second deformation unit has a smaller cross-sectional width than the first deformation unit. Such a joining structure may be utilized to couple elements together in a display device, such as a plasma display device.
