Abstract: A display device includes a display panel, a support film, and a polymer layer. The display panel includes a display area comprising a first area that is bendable, and a non-display area adjacent to the display area. The support film is coupled to a bottom surface of the display panel. The support film includes a first groove overlapping with the first area. The polymer layer is disposed in the first groove. The polymer layer includes a material with higher flexibility than the support film. Angles formed by the top surface of the support film and inner sides of the support film defining the first groove are acute angles.

Abstract: A manufacturing method of a display device, includes: providing a display module bendable at a bending area and including: a passivation film including a polyimide and disposed both in and outside of the bending area, and an adhesive layer attaching a display panel to the passivation film and including a first adhesive portion in the bending area and a second adhesive portion outside of the bending area; reducing an adhesive force of the first adhesive portion, by irradiating a first laser which is a CO2 laser to the adhesive layer at the bending area, to provide the first adhesive portion which has reduced adhesive force; providing a groove in the passivation film and the adhesive layer, along a boundary of the bending area; and removing the passivation film and the first adhesive portion which has the reduced adhesive force, from the display panel, at the groove.

Abstract: A laser ablation apparatus includes: a laser beam generator including beam sources for generating laser beams, the laser beam generator using a solid-state laser; an output beam generator for generating an output beam using the laser beams; and a substrate stage including at least one stage on which a carrier substrate formed on the front of a panel substrate is disposed. The output beam generator may include: mixers for generating mixed laser beams having two linear-polarizations orthogonal to each other by mixing the laser beams; and a photo molding machine for generating the output beam using the mixed laser beams.
