ABSTRACT:
In an image display panel: in which at least one group of particles or liquid particles is sealed between opposed substrates, at least one of two substrates being transparent; in which the particles or the liquid powders, to which an electrostatic field is applied, are made to move so as to display an image; and in which partition walls arranged between the substrates according to need, use is made of the substrate in which at least a surface, to which the particles or the liquid powders are contacted, is subjected to a hydrophobic treatment (first aspect), at least a surface of the partition wall, to which the particles or the liquid powders are contacted, is subjected to a hydrophobic treatment (second aspect), at least a surface of the partition wall, to which the particles or the liquid powders are contacted, is coated by a material having a small charge decay property (third aspect), a universal hardness of a binder resin used for a material constituting the partition wall is not less than 400 N/mm2, which is obtained by a method of measuring a universal hardness in which the binder resin constituting the partition wall having a thickness of 3 μm is formed on a glass substrate having a universal hardness of 2000 N/mm2(fourth aspect), a ratio Lh/Lw between a height Lh and a width Lw of the partition wall satisfies 0.5≦Lh/Lw≦20 (fifth aspect), and the partition wall has a predetermined drying function (sixth aspect).
