Electrophoretic device having an opening
View Patent ↗An electrophoretic display device of the present invention is formed of a first substrate, a second substrate, and microcapsules which are accommodated between these substrates and which contain an electrophoretic dispersion, wherein each of the microcapsules has an opening in at least a part thereof.
1. A method for manufacturing an electrophoretic device, comprising:
a step of enclosing a dispersion medium and electrophoretic particles in capsules; and
a step of forming an opening portion in at least a part of each of the capsules after the enclosing step.
2. A method for manufacturing an electrophoretic device, comprising:
a step of enclosing a dispersion medium and electrophoretic particles in capsules;
a step of accommodating the capsules between a first substrate and a second substrate after the enclosing step; and
a step of forming an opening portion in at least a part of each of the capsules after the accommodating step.
3. A method for manufacturing an electrophoretic device, according to claim 2 ,
wherein the capsules are accommodated with a binding agent between the first substrate and the second substrate.
4. A method for manufacturing an electrophoretic device, comprising:
a step of enclosing a dispersion medium and electrophoretic particles in capsules;
a step of disposing the capsules on at least one of a first substrate and a second substrate after the enclosing step;
a step of forming an opening portion in at least a part of each of the capsules after the disposing step; and
a step of providing the other of the first and second substrate on the at least one substrate on which the capsules are disposed.
5. A method for manufacturing an electrophoretic device, according to claim 4 ,
wherein the capsules are disposed together with a binding agent on at least one of the first substrate and the second substrate.
6. A method for manufacturing an electrophoretic device, according to claim 4 , wherein the step of forming the opening operation comprises an opening step performed by using at least one of the group selected from heat, mechanical stress, light, sonic waves, solvents, and corrosive gases.
7. A method for manufacturing an electrophoretic device, according to claim 6 , wherein the binding agent has at least one property selected from the group of volatility, contractility, plasticity, and flexibility.
