Abstract

There is provided a charged particle migration-type display panel ( 1 ) which has a plurality of cells ( 40 ) partitioned by partitions ( 31 ) between a transparent substrate ( 10 ) and a back substrate ( 20 ) placed opposite to each other, and charged particles ( 41, 42 ) sealed in the respective cells ( 40 ), and in which the partitions ( 31 ) provided upright on the back substrate ( 20 ) are formed of a translucent material, and the tips and the side faces of the partitions ( 31 ) are covered with a resin ( 32 ) containing an opaque or semi-transparent dark-colored coloring material, thereby forming a black matrix structure.

Claims (6)

1. A charged particle migration-type display panel comprising:

a plurality of cells partitioned by partitions between two substrates placed opposite to each other, with charged particles sealed in the respective cells, wherein

the partitions provided upright on one of the substrates are formed of a translucent material,

the partition is formed into a tapered shape or a wedge shape, and

tips of the partitions and at least parts of side faces thereof are covered with a resin containing an opaque or semi-transparent dark-colored coloring material to form a black matrix structure,

wherein the resin is set taller than the partition, and a width of a lower end of the resin is set wider than a width of a lower end of the partition, so that the whole partitions are covered with the resin thereby forming a black matrix structure.
