Title:
DIMMING SHEET AND LAMINATED GLASS
Document Type and Number:
Japanese Patent JP2020177039
Kind Code:
A
Abstract:
To propose a configuration of a peripheral seal part that is also effective in improving design in addition to improving a waterproof function by sealant, and in particular, improve an actual situation where poor appearance occurs due to the structure of the peripheral seal part when a dimming sheet is made into a laminated glass form.SOLUTION: At an outer peripheral end of a dimming sheet, end faces of a first transparent conductive film and a liquid crystal layer are cut so as to be inside an end face of a second transparent conductive film. The length in a thickness direction of a seal portion that protects the liquid crystal layer exposed at the cut end is smaller than the sum of the thickness of a pair of transparent conductive films and the thickness of the liquid crystal layer. The seal portion is not outside outer surfaces of the first and second transparent films in the thickness direction of the dimming sheet.SELECTED DRAWING: Figure 1
