Estimating the term…
Provisions of a large screen, thin sheet-like display device capable of realizing usages just like paper, a sphere-like resin body made of two semispheres capable of being manufactured easily, and a microcapsule containing electrophoretic particles capable of being manufactured easily. The sheet-like display device 10 has a sheet-like display layer 12 and at least one layer 14 containing an element for activating the sheet-like display layer, the layers being integrally formed. The sphere-like resin body has first and second portions made of resins, the absolute value of a difference between both the solubility parameters δ1 and δ2 of the resins being |δ1−δ2|≧0.2. The phoretic particle-containing microcapsule has a resin shell in which phoretic particles are contained in a core. The diameter of the core is in a range from 10 μm to 200 μm and the circumferential length L of the microcapsule is in a range of (4.1×T)≦L≦(20.1×T) where T is a Martin diameter of the microcapsule.
