Title:
a modulated light film -- and -- uniting -- glass
Document Type and Number:
Japanese Patent JP6213653
Kind Code:
B2
Abstract:
The purpose of the present invention is to, for example, even when a light control film is used as an intermediate material of laminated glass, enable effective avoidance of a reduction in external appearance quality, and sufficiently stable driving, and prevent diffracted light from being discerned by effectively avoiding a reduction in transmittance and a deterioration in liquid crystal alignment. A light control film 1 is provided with: a first laminate 13 in which an alignment layer 23B is provided; a second laminate 12 in which an alignment layer 23A is provided; a liquid crystal layer 14 which is sandwiched between the first laminate 13 and the second laminate 12 and contains liquid crystal molecules; a spacer 24 which is disposed in the liquid crystal layer 14 to hold the thickness of the liquid crystal layer 14; and electrodes 22B, 22A provided in the first laminate 13 and/or the second laminate 12, and controls transmitted light by controlling the alignment of the liquid crystal molecules by driving by the electrodes 22B, 22A, wherein the proportion of an area occupied by the spacer 2 per unit area when the light control film 1 is viewed from the front in a light controllable-region of the liquid crystal layer is 0.1-10% inclusive.
