Title:
MANUFACTURING METHOD FOR MULTILAYER STRUCTURE FOR IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/194958
Kind Code:
A1
Abstract:
Proposed is a manufacturing method for a multilayer structure for an image display device, the multilayer structure being formed by interposing at least a portion of a frame (3) between a screen display panel (2) and a front surface panel (4) and affixing the screen display panel and the front surface panel with a double-sided adhesive sheet (5), wherein: the double-sided adhesive sheet is designed so that a prescribed formula is satisfied by the thickness and area of the double-sided adhesive sheet prior to affixing, and the maximum thickness of the double-sided adhesive sheet after fixing and the area of the valid image display surface of the image display panel; and the manufacturing method includes the following steps. (a) A step for producing a double-sided adhesive sheet by molding, into a sheet shape, an adhesive compound which was crosslinked by active energy ray projection. (b) A step for producing a multilayer structure by interposing the frame between the screen display panel and the front surface panel and stacking the screen display panel and the front surface panel with the double-sided adhesive sheet interposed therebetween. (c) A step for softening the double-sided adhesive sheet. (d) A step for projecting active energy rays onto the double-sided adhesive sheet.
