摘要： An initial resin substrate is formed by laminating resin layers, and one surface of the initial substrate is heated and pressed by a molding die to mold a projected and dented surface such that substantially no deformation occurs on the resin layer providing a surface opposed to the one surface of the initial substrate. A reversible image display medium is produced by a method comprising the steps of accommodating a dry developer into the concavities and fixing a second substrate to the first substrate using an adhesive. Alternatively a reversible image display medium may be produced by, e.g., a method comprising the steps of providing a first substrate having one surface including concavities, spreading the dry developer over the one surface, removing the excess developer while accommodating the developer into the concavities, and fixing a second substrate to the one surface, or alternatively forming a cell sheet having the cells and accommodating a dry developer therein by use of supersonic oscillation, magnetic force or vacuum suction force.
