LIGHT CONTROL FILM AND LAMINATED GLASS
To provide a light control film that can effectively avoid reduction in external appearance quality of a product and can be sufficiently stably driven even when the film is used as intermediate material of laminated glass, and that can effectively avoid reduction in transmittance and degradation in aligning property of liquid crystal and prevents diffracted light from being seen.SOLUTION: A light control film 10 includes: a first laminate 13; a second laminate 12; a liquid crystal layer 14 sandwiched between the first laminate 13 and the second laminate 12 and comprising liquid crystal molecules 14A; a spacer 24 disposed in the liquid crystal layer 14 to hold thickness of the liquid crystal layer 14; and electrodes 22B and 22A disposed on the first laminate 13 and/or the second laminate 12. The spacer 24 has a columnar shape. A proportion of area occupied by the spacer 24 per unit area in a light-controllable region of the liquid crystal layer 14 in a frontal view of the light control film 10 is 0.5% or more and 10% or less.SELECTED DRAWING: Figure 2
【課題】合わせガラスの中間材に利用する場合等においても、外観品位の低下を有効に回避して十分に安定に駆動することができ、また透過率の低下、液晶の配向性の低下を有効に回避して回折光が見て取られたりすることが無いようにする。【解決手段】調光フィルム１０は、第１の積層体１３と、第２の積層体１２と、第１の積層体１３及び第２の積層体１２により挟持されるとともに液晶分子１４Ａを含む液晶層１４と、液晶層１４に配置された、液晶層１４の厚みを保持するスペーサー２４と、第１の積層体１３及び又は第２の積層体１２に設けられた電極２２Ｂ，２２Ａとを備え、スペーサー２４が柱形状であり、液晶層１４の調光可能領域における、調光フィルム１０を正面視した場合の単位面積当たりのスペーサー２４の占有面積の割合が、０．５％以上１０％以下である。【選択図】図２
