METHOD FOR PRODUCING INDIVIDUALIZED FILM, INDIVIDUALIZED FILM, METHOD FOR PRODUCING DISPLAY DEVICE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/057755
Kind Code:
A1
Abstract:
The present invention provides: a method for producing an individualized film, the method enabling the achievement of excellent processability of an individualized piece; an individualized film; a method for producing a display device; and a display device. According to the present invention, an anisotropic conductive film (22) that is provided on a base material (21) is irradiated with laser light from the base material (21) side so as to remove the anisotropic conductive film (22) (a removal part (23)) in the irradiated portion, thereby forming an individualized piece which is formed of the anisotropic conductive film (22) and has a predetermined shape. Meanwhile, the thickness of the anisotropic conductive film (22) is 1 µm to 10 µm; the melt viscosity of the anisotropic conductive film (22) at 30°C is 2,000 Pa∙s to 800,000 Pa∙s; and 90% or more of conductive particles in the anisotropic conductive film (22) are present on the average value of the center positions of the conductive particles in the thickness direction of the anisotropic conductive film (22). Consequently, the present invention enables the achievement of excellent processability of an individualized piece, thereby being capable of improving the takt time.
