A method for introducing openings into a decorative material laminated onto a carrier comprises the following steps: providing a fixing device with at least two indicator pins and at least one absorption chamber, providing a carrier with holes for receiving the indicator pins and a decorative material with holes for receiving the indicator pins, pushing the carrier onto the indicator pins and then pushing the decorative material onto the indicator pins. The indicator pins extend through the holes in the carrier and the decorative material and visible parts of the indicator pins protrude above the decorative material, and the decorative material is positioned on the carrier and laminated onto the carrier. Openings are introduced into the decorative material above the openings in the carrier by means of a laser, by detecting the positions of the indicator pins and the heights of the visible parts of the indicator pins.

A method is disclosed for dividing a composite material 10 including a brittle material layer 1 and a resin layer 2 that are laminated together, the method includes: a resin removing step of applying laser light L1 oscillated from a CO.sub.2 laser light source 20 to the resin layer along a planned division line DL of the composite material, so that a processed groove 24 is formed along the planned division line; and a brittle material removing step of applying, after the resin removing step, laser light L2 oscillated from an ultrashort pulsed laser light source 30 to the brittle material layer along the planned division line, so that processed marks 11 are formed along the planned division line. The processed marks formed in the brittle material removing step open on the resin layer side and do not penetrate through the brittle material layer.

A method for fabricating a display panel including a bending area includes: providing a substrate; forming a first flexible layer on the substrate; forming an organic layer on the first flexible layer, wherein a wavelength of light absorbed by the organic layer is different from a wavelength of light absorbed by the first flexible layer; irradiating a part of the organic layer in the bending area with a laser to make at least a portion of the part of the organic layer a carbonized layer, thereby forming a spacer layer; forming a second flexible layer covering the first flexible layer and the spacer layer, wherein the first flexible layer and the second flexible layer are made of a same material and separated by the spacer layer; and cutting a part of the substrate and a part of the first flexible layer in the bending area.
