Title:
LIGHT CONTROL SHEET, LIGHT CONTROL DEVICE AND METHOD FOR PRODUCING LIGHT CONTROL SHEET
Document Type and Number:
WIPO Patent Application WO/2024/058041
Kind Code:
A1
Abstract:
According to the present invention, a light control layer (31) comprises: an ionizing ray curable resina layer (31P) which defines a void (31D); and a liquid crystal composition (31LC) with which the void (31D) is filled. A first acrylic compound has a functionality of 3 or more, while having a double-bond equivalent weight of 150 g/eq or less. A second acrylic compound is a monofunctional alkyl acrylate which has a saturated alkyl group. A third acrylic compound has one to three functional groups and a polyethylene oxide chain, while having a double-bond equivalent weight of 300 g/eq to 700 g/eq. The content of the first acrylic compound is 5% by mass to 40% by mass. The content of the second acrylic compound is 55% by mass to 80% by mass. The content of the third acrylic compound is 5% by mass to 20% by mass. Consequently, this light control sheet can be driven in a low temperature environment.
