Particularly, since the upper electrostatic chuck 60 is provided with a viewer hole region having a model-specific viewer hole so as to correspond to various models, the area of the upper electrostatic chuck 60 to be adsorbed is further reduced.

Second, by using the electrostatic chucks 30 and 50 for supporting the display panel 1 and the transparent cover 2, the attraction force is low and the structure is complicated.

Thirdly, since the positions of the display panel 1 and the transparent cover 2 are aligned through the movement of the lower stage 20 in the gap space between the driving shaft 80 and the lower chamber 10, The volume of the interior of the lower chamber 10 for forming the vacuum chamber is large, thereby increasing the process tact time as the time for forming the vacuum is increased.
