A substrate-cutting method includes preparing a first substrate in which a plurality of first active areas spaced apart from each other and a first non-active area surrounding the first active areas are defined in a plane, forming an adhesive layer on the first substrate where the adhesive layer is disposed within the first active areas, disposing a second substrate in which a plurality of second active areas spaced apart from each other and a second non-active area surrounding the second active areas are defined in the plane, and cutting a cutting line of the second substrate, which corresponds to a boundary between the second active areas and the second non-active area, using a laser beam. The adhesive layer does not overlap the cutting line of the second substrate.

Substrate-stacking structure and substrate-cutting method

A display device includes a display module including: a folding area, and first and second non-folding areas; a first support member bendable together with the display module and including: a bending area corresponding to the folding area, and first and second non-bending areas corresponding to the first and second non-folding areas; and a support layer facing the display module with the first support member therebetween, and including: a second support member in the bending area and the first and second non-bending areas; a first support plate facing the first support member with the second support member therebetween and in the bending area and the first non-bending area; and a second support plate facing the first support member with the second support member therebetween and in the bending area and the second non-bending area. The second support plate is disconnected from the first support plate at the bending area.

Display device

A display apparatus includes: a substrate including a display area and a peripheral area; a thin-film encapsulation layer overlapping the display area and including an inorganic film and an organic film; a conductive layer located in the peripheral area; and a dam overlapping an outer edge of the conductive layer, wherein the dam includes a first inclined portion extending from a top surface of the dam toward the display area and at least partially overlapping the conductive layer and a second inclined portion extending in an opposite direction to the first inclined portion. A shape of the first inclined portion and a shape of the second inclined portion are asymmetric to each other.

Display apparatus and mask for manufacturing the same

A dummy removal device includes a picker picking a point of a dummy portion of a preliminary display module and moving in a first moving direction to separate a first portion of the dummy portion from the preliminary display module; and a separator disposed adjacent to the separated first portion and moving in a second moving direction intersecting the first moving direction to remove a second portion of the dummy portion from the preliminary display module, and the dummy portion is disposed around an effective portion of the preliminary display module.

Dummy removal device and method of driving the same

A display device may include a first non-folding region, a second non-folding region, and a folding region. The display device may include a display member including a display module, a supporting member supporting the display member, an adhesion member disposed between the display member and the supporting member, and a compensation member attached to one of top and bottom surfaces of the adhesion member and overlapped with the folding region. Thus, it may be possible to provide a display device configured to reduce a stress, which is exerted on a folding region when it is in a folded state, and to prevent the folding region from being deformed to a bent shape when it is in an unfolded state.

The display device includes a display module which displays an image at a front surface of the display module and includes a rear surface, a folding area and a non-folding area extended from the folding area; and a supporter facing the rear surface of the display module and including a first portion corresponding to the non-folding area, a second portion corresponding to the folding area, and a boundary between the first portion and the second portion. The display module which is unfolded disposes the supporter bent at the boundary, and the supporter which is bent includes the first portion and the second portion together forming a curvature of the supporter having a center of curvature at the front surface of the display module.
