Abstract: A bonding apparatus includes a support including a cavity, and a window fixing chuck facing the support. The support includes a first part including a first through hole extending from the cavity, and a second part extending in a downward direction from the first part and including a second through hole extending from the cavity. A first distance between a first inner surface of the first part and a first outer surface of the first part is less than a second distance between a second inner surface of the second part and a second outer surface of the second part. The first inner surface of the first part and the second inner surface of the second part form the cavity.

Abstract: A display apparatus includes a roller extending in a first direction and a display module coupled to the roller. The roller includes a cylinder body having an inner accommodation space, and the cylinder body defines a slot that exposes the inner accommodation space to the outside and extends in the first direction. An outer surface of the cylinder body includes a support surface spaced apart from an axis of the cylinder body by a first distance and a guide surface extended to or from the support surface and recessed a predetermined distance toward the axis such that a distance to the axis is less than the first distance. The guide surface is extended to or from a first end of the slot.

Abstract: Provided is a window molding apparatus including an inner molding part including a core molding part, which includes a plurality of sub-bottom surfaces having different curvature radii, and a flat molding part spaced apart from the sub-bottom surfaces and disposed on the core molding part, and an outer molding part which is disposed below the inner molding part with a member to be processed therebetween and in which a groove corresponding to the core molding part is defined. The outer molding part includes a lower surface, an upper surface configured to face the lower surface, and a plurality of sub-groove surfaces having different curvature radii that define the groove to provide a window including sub-bent portions having different curvature radii.
