Abstract
A magnetophoresis type display device, according to one embodiment, is provided with a transparent front panel sheet, a back panel sheet arranged with respect to the front panel sheet so as to form a sealed space with it, a partitioning member provided between the front panel sheet and the back panel sheet for partitioning the sealed space into a large number of cells and a liquid dispersion containing magnetic particles and a single-color fluid to be sealed inside the cells formed by partitioning by the partitioning member. The single-color fluid is a white fluid that includes at least titanium oxide and silicon oxide in which when the total weight of the white fluid is 100 wt %, the wt % of the titanium oxide in the white fluid is C, and the wt % of the silicon oxide is D, the weight ratio C/D is in the relationship of 1≦C/D≦2.5.
