In the adhesive pad 132, the adhesive 130 has adhesiveness. Therefore, the second substrate 20 is adhered to the adhesive pad 132. The adhesive pad 132 may have elasticity. The adhesive pad 132 may be a rubber, a synthetic rubber, a fluorocarbon rubber, or a Viton rubber having adhesiveness.

The adhesive force of the adhesive pad 132 can be controlled by a chemical change during the manufacturing process. The adhesive force of the adhesive pad 132 may be changed depending on the degree of adhesion between the second substrate 20 and the second substrate 20. As the degree of contact between the second substrate 20 and the adhesive pad 132 increases, the area of contact with the second substrate 20 increases. Accordingly, the adhesive force of the adhesive pad 132 increases as the area of contact with the second substrate 20 increases.

The adhesive pad 132 is formed to protrude from the lower surface of the stage 140 toward the first support portion 110. The adhesive pad 132 may be detachably attached to the adhesive chuck 131. Accordingly, the adhesive pad 132 can be replaced.

The diaphragm 151 is formed in the form of a thin film having elasticity or stretchability and is installed on the adhesive chuck 131. Accordingly, the diaphragm 151 can be expanded or contracted depending on whether the pneumatic pressure is supplied from the pneumatic supply mechanism 152 or not. That is, the diaphragm 151 is inflated when the air pressure is supplied from the air pressure supply mechanism 152, and may be contracted if no air pressure is supplied from the air pressure supply mechanism 152. The diaphragm 151 is inflated by air pressure to separate the second substrate 20 from the adhered portion 130.

The substrate separating unit 150 may further include a pneumatic pipe 153 for guiding a pneumatic pressure supplied from the pneumatic supply mechanism 152. The pneumatic piping 153 connects the pneumatic supply mechanism 152 and the diaphragm 151.

The elevation part 160 moves the second substrate 20 adhered to the adhesion part 130 from the adhesion part 130 by raising the adhesion part 130 and inserting the adhesion part 130 into the elevation guide groove 141 Can be separated. The second substrate 20 is separated from the adhesive 130 by contacting the lower surface of the stage 140 as the adhesive 130 is retracted in the direction in which the adhesive 130 is inserted into the elevation guide groove 141. The second substrate 20 is detached from the adhered portion 130 and then dropped on the substrate adhering member (not shown) formed on the first substrate 10, ). ≪ / RTI > Here, the first and second substrates 10 and 20 may be bonded to each other by a vent process for converting a vacuum atmosphere of the process chamber to an atmospheric pressure atmosphere.

When the diaphragm 151 is inflated, the lifting unit 160 can raise the adhesive 130. The lifting unit 160 may lift the adhesive 130 at the same time as the diaphragm 151 is expanded. The elevation part 160 raises the adhesion part 130 to increase the adhesion between the second substrate 20 and the adhesive part 130 by the expansion of the diaphragm 151, The substrate 20 can be separated. That is, the second substrate 20 is detached from the adhesive 130 due to the expansion of the diaphragm 151, and contacts the lower surface of the stage 140 as the adhesive 130 is lifted, (130) and dropped onto the first substrate (10). Accordingly, the apparatus for attaching the display panel according to the present invention can efficiently separate the second substrate 20 from the adhered portion 130 by operating the elevation portion 160 after the operation of the diaphragm 151 have. That is, when the diaphragm 151 is operated after the lifting unit 160 is raised (or retracted) first, due to the strong adhesive force between the adhesive pad 132 and the second substrate 20, The substrate 20 is not detached from the adhesive pad 132 and the adhesive portion of the second substrate 20 adhered to the adhesive pad 132 rises with the rise of the adhesive pad 132, So that the shape of the body 20 is deformed. In order to prevent the deformation of the second substrate 20, the elevating unit 160 preferably operates after the diaphragm 151 operates.
