Document Type and Number:
WIPO Patent Application WO/2019/103115
Kind Code:
A1
Abstract:
Provided are a liquid crystal film and laminated glass that are capable of reducing liquid crystal accumulation and the occurrence of air gaps. This laminated glass (1) has a form in which a light-modulating film (10) is sandwiched between a first glass sheet (33A) and a second glass sheet (33B), and the light-modulating film (10) is provided with, in order in the thickness direction, a first base material layer (21A), a first transparent electrode layer (22A), a liquid crystal layer (14), a second transparent electrode layer (22B), and a second base material layer (21B). The liquid crystal layer (14) is provided with, within the layer, a plurality of spacers (24) for maintaining the thickness thereof. The first base material layer (21A) and the second base material layer (21B) each satisfy t×Y≥215 (μm×GPa), with t (μm) being the thickness thereof and Y (GPa) being the Young's modulus. The spacers (24) are provided in an amount of at least 60 spacers per 1 mm2.
