Title:
METHOD FOR MANUFACTURING TRANSPARENT INSULATING COLUMNAR STRUCTURE FOR TRANSPARENT SPEAKER, TRANSPARENT SPEAKER MODULE, TRANSPARENT SPEAKER, PHOTOSENSITIVE RESIN COMPOSITION AND PHOTOSENSITIVE ELEMENT
Document Type and Number:
Japanese Patent JP2019041260
Kind Code:
A
Abstract:
To provide a method for manufacturing a columnar structure to achieve both of an insulating property and the shapability enough to mold a columnar structure without a defect, thereby complying with the need for forming a transparent columnar structure in order to support a speaker vibration plate in addition to insulation between a conductive layer face of a transparent speaker substrate and a conductive layer of the vibration plate in use of a transparent speaker.SOLUTION: A method for manufacturing a columnar pattern according to the present invention comprises the steps of: providing, on a substrate for a transparent speaker, a layer of a photosensitive resin composition containing a binder polymer, a photopolymerizable compound and a photoinitiator, applying an activation beam to the photosensitive resin composition layer to adjust a reaction rate of the photopolymerizable compound and cure it, thereby forming an insulating film composed of a cured product of the photosensitive resin composition; and thereafter, providing a layer of a photosensitive resin composition on the insulating film, and curing a predetermined part of the photosensitive resin composition layer by applying an activation beam, and then removing a part of the photosensitive layer other than the predetermined part, thereby forming a columnar structure composed of a cured product of the photosensitive resin composition.SELECTED DRAWING: Figure 1
