Abstract
In a display device that includes a display space provided on a display surface side and a liquid sealed inside the display space so as to be operable and is constituted so as to be able to change a display color on the display surface side according to an application of an electric field to the liquid, the liquid is an ionic liquid containing an ambient temperature molten salt combining a cation and an anion. Further, an amount of water blended in the liquid is 0 to 10 parts by weight with respect to 100 parts by weight of the ionic liquid. This makes it possible both to reduce a voltage to be applied to the liquid so as to allow driving at a low voltage and to improve an operation performance.
