Abstract: Provided is a perfume retaining member which is easy to handle and in which perfume can be stored for a long period of time without leakage. The perfume retaining member 101 includes: a housing 111 that includes an internal space, a first opening 117 and a second opening 118 that open the internal space to an outside, and movable portions 113 and 114 that are movable to open and close at least one of the first opening 117 or the second opening 118; a perfume storage unit 120 that stores perfume in a sealed manner; a perfume releasing mechanism 124 that releases the perfume from the perfume storage unit 120; and an impregnating material 115 in which the perfume released from the perfume storage unit 120 impregnates to be retained. The movable portions 113 and 114 seal the first opening 117 and/or the second opening 118 in a normal state, and open the first opening 117 and/or the second opening 118 when the internal space is opened.

Abstract: Liquid crystal is prevented from leaking out into a terminal hole in a liquid crystal injection process, and the productivity of a liquid crystal light control device is improved. A liquid crystal light control device according to the present technology includes a plurality of liquid crystal layers, terminals provided for respective electrodes disposed to face each other across the liquid crystal layers, and terminal holes formed above the terminals, and an injection mark of a liquid crystal for the liquid crystal layer is formed on a back face side which is a face on a side opposite to a face that has been opened by the terminal hole.
