Abstract: In an airtight container manufacturing method including sealing a through-hole by a cover, it secures sealing performance and restrains a sealant from flowing into the through-hole. The method comprises: (a) exhausting the inside of a container (1) through the through-hole (5) provided on the container; (b) arranging a plate member (8) having, at its periphery, grooves penetrating the plate member in its plate thickness direction on the outer surface of the container the inside of which has been exhausted, so as to close up the through-hole; and (c) arranging the cover (13) so as to cover the plate member via the sealant (12) and bonding the cover and the outer surface of the container via the sealant, wherein the sealing includes hardening the sealant after deforming the sealant as pressing the plate member by the cover so that the sealant is positioned between the cover and the outer surface of the container via the grooves.

Abstract: A chiral smectic liquid crystal device with a good planar homogeneity in a layer normal direction can be constituted by disposing a chiral smectic liquid crystal having no cholesteric phase between a pair of substrates having mutually different characters, particularly in terms of Iso - SmA phase transition temperature. The liquid crystal may preferably have a layer spacing-changing characteristic such that it provides a layer spacing dA at a first transition point where the layer spacing of the liquid crystal begins to decrease on temperature decrease in the vicinity of a transition temperature from SmA phase to SmC* phase and a layer spacing dmin at a second transition point where the layer spacing of the liquid crystal begins to increase on further temperature decrease from the first transition point, satisfying 0.96

Abstract: PROBLEM TO BE SOLVED: To control the influence of anti-electric field in the case of switching liquid crystal and to reduce asymmetry in the switching by providing an electrode on either of base plates, an electric characteristic control layer on the electrode and an orientation control layer having specified thickness and a volume resistance larger than the electric characteristic control layer on the electric characteristic control layer. SOLUTION: A pair of base plates 101 and 102 is arranged to be opposed and the electrodes 103 and 104 are respectively formed in specified pattern shape on the base plates. The electrodes 103 and 104 are formed in a stripe state and arranged to substantially orthogonally cross with each other, so that matrix electrode structure is formed. The base plates 101 and 102 are opposed through a specified distance and interpose the liquid crystal 109, for example, the liquid crystal showing a chiral smetic phase. The electric characteristic control layer 105 is the layer having a smaller volume resistance value than the oriented control layer 107 of the upper layer has. The layer 107 is formed on the layer 105, and its layer thickness is set to
