Patent ID: 7682651

Claim:
A method for manufacturing a display device having hollows containing fine particles for displaying an image by controlling the distribution of the fine particles, the hollows being defined by a substrate, a plurality of partitions arranged on the substrate, and a support layer placed on the partitions; the support layer having a face (i) opposed to the substrate and (ii) covered with a sealing layer; the partitions having end portions covered with the sealing layer, the method comprising: a step of providing a dispersion in the hollows, the dispersion containing the fine particles, a dispersion medium and a sealing layer precursor containing an amphipathic compound, dissolved or dispersed in the dispersion medium for forming the sealing layer; a step of providing the support layer on the partitions; a step of extending the sealing layer precursor between the face of the support layer and the end portions of the partitions and allowing the face of the support layer and the end portions of the partitions to absorb the sealing layer precursor, the face of the support layer and the end portions of the partitions being in contact with the dispersion; and a step of forming the sealing layer by subjecting the coated precursor to at least one of polymerization and cross-linking.
