Abstract: A light control sheet includes two transparent substrate layers each including an electrode layer, and a light control layer formed between the two transparent substrate layers. The light control layer includes a transparent resin layer defining a void, a liquid crystal composition filling the void, and a spacer that determines a thickness of the light control layer. Each transparent substrate layer in the light control sheet has external haze of less than 0.1%, and each transparent substrate layer in the light control sheet has internal haze of 0.1% or more and 2.0% or less.

Abstract: A light control sheet is reversibly changeable between transparent and opaque in response to a change in alignment of a liquid crystal compound. The light control sheet includes a light control layer including a polymer resin layer in which voids are dispersed, and a liquid crystal composition containing the liquid crystal compound. The liquid crystal composition is filling the voids. In the light control layer, a percentage of a volume of the liquid crystal composition relative to a total volume of the polymer resin layer and the liquid crystal composition is 40% or greater and 60% or less. Avoid diameter of the voids is 2 μm or less.

Abstract: A display device includes a substrate, a barrier layer, light-emitting diodes, and lenses. The barrier layer is provided on the substrate. The barrier layer has through holes. The light-emitting diodes are disposed in the through holes. The lenses is disposed at positions of the through holes. Each of the lenses has a first surface and a second surface, the second surface is a convex surface, and height of a top of the convex surface based on the substrate is greater than a height of an upper surface of the barrier layer based on the substrate. The first surface is opposed to the substrate with the light-emitting diode therebetween. The second surface is a back of the first surface.

Abstract: A battery pack includes: a case; a plurality of batteries housed in the case; at least one of a heat-insulating material or an endothermic material disposed between the plurality of batteries; and a fire extinguisher disposed in the case. The heat-insulating material suppresses heat transfer to adjacent batteries when a battery is ignited. The heat-insulating material also blocks heat after the fire is extinguished by the action of the fire extinguisher.

Abstract: A evaluation method of an anticancer drug includes culturing a cell structure containing a cancer cell and a stromal cell in a presence of one or two or more of anticancer drugs and evaluating an anticancer effect of the anticancer drug using, as an index, the number of cells having a proliferation ability of the cancer cell in the cell structure after the culturing, in which a signal transduction pathway in the cancer cell stimulated by a hepatocyte growth factor, a placental growth factor, or a vascular endothelial growth factor is more activated than a signal transduction pathway in a normal cell.
