Problems solved by technology

[0007] Although the liquid crystal film that does not use a sealing material can prevent the intrusion of air or moisture from the outside of the dimming window by the intermediate film, because the liquid crystal layer of the liquid crystal film is in direct contact with the intermediate film, the liquid crystal layer is contained by the intermediate film. The damage of the plasticizer of the liquid crystal film causes problems such as the deterioration of the liquid crystal layer near the peripheral part of the liquid crystal film.

[0046] Such as figure 1 As shown, the sealing tape 10 includes: a strip-shaped base material 11; an adhesive portion 12 formed by disposing an adhesive on both edge portions 11a in the longitudinal direction of the base material 11; The area between the two edge portions 11a of the base material 11 is exposed along the length direction of the base material 11;

[0047] The base material 11 is a film with transparency, insulation, flexibility, toughness, heat resistance, cold resistance or chemical corrosion resistance, such as a polyester film, especially polyethylene terephthalate : PET) film. In addition, the base material 11 which concerns on this embodiment uses "Lumira (registered trademark)" manufactured by Toray Co., Ltd. with a width of 6 mm.

[0048] Adhesive portion 12 may be formed by directly applying an adhesive to base material 11 and drying the applied adhesive, or may be formed by affixing one side of the base material 11 with a double-sided adhesive tape. I...

Abstract

Provided is a seal tape that can prevent deterioration of a light modulating layer by an intermediate film that includes a plasticizer and that can also improve workability during the production of a light modulating structure. The seal tape (10) comprises: a band-like base material (11); an adhesive section (12) formed by the provision of an adhesive on both edges (11a) in the longitudinal direction of the base material (11); an exposed section of base material (11b) that extends in the longitudinal direction of the base material (11) and is a region between both edges (11a) of the base material (11) located on the surface on which the adhesive section (12) is formed; and a releasing material (13) which covers the adhesive section (12) on both edges (11a) of the base material (11).

Description

technical field [0001] The present invention relates to a sealing tape that is arranged on the periphery of a pair of insulating substrates and seals a light-adjusting layer of a light-adjusting element, a light-adjusting element using the sealing tape, a light-adjusting structure, and a method for manufacturing a light-adjusting structure. The dimming element includes: a pair of substrates (hereinafter referred to as insulating substrates) at least one of which is transparent and insulating; transparent electrodes respectively arranged on the pair of insulating substrates; The lead-out electrodes electrically connected to the transparent electrodes exposed on the opposite surfaces of the insulating substrates; and the dimming layer sandwiched between a pair of insulating substrates. Background technique [0002] In recent years, dimming windows in which dimming elements such as liquid crystal films and dimming films are laminated on glass substrates have been used for windo...
