The first electrode layer 110 is a transparent electrode layer. Each microcup structure 120 includes a base 122 and a plurality of partition walls 124 . The base 122 of each microcup structure 120 is disposed on the first electrode layer 110 , and the partition walls 124 of each microcup structure 120 are disposed on the corresponding base 122 . In the conventional electrophoretic display 100 , the microcup structures 120 are neatly distributed on the first electrode layer 110 in an array.

The electrophoretic fluid 130 fills the microcup structures 120 , and the electrophoretic fluid 130 includes a dielectric solvent 132 and a plurality of charged pigment particles 134 . The charged colored particles 134 are dispersed in the insulating solvent 132 , one side of each charged colored particle 134 is white, and the other side is black.

The second electrode layer 140 is disposed on each microcup structure 120 and opposite to the first electrode layer 110 . The sealing layer 150 is disposed between each microcup structure 120 and the second electrode layer 140 , and the second electrode layer 140 is disposed on the sealing layer 150 through the adhesive layer 160 .

When the conventional electrophoretic display 100 operates, the first electrode layer 110 and the second electrode layer 140 and each microcup structure 120 generate different electric fields. At this time, the charged colored particles 134 will move to the bases 122 , and the charged colored particles 134 will rotate in different ways, and then present different colors to display certain information. Therefore, the user can view the electrophoretic display 100 from the viewing direction D1 shown in FIG. 1A to interpret the displayed information (information is information).

In addition, the conventional electrophoretic display 100 can be bent so as to be convenient for users to use or carry. However, when the conventional electrophoretic display 100 is bent, the intersection I1 of the partition walls 124 adjacent to the microcup structures 120 is where the stress concentrates. Due to the consideration of the structural strength of the containing structure 12 , the thickness 124a of each partition wall 124 cannot be too small, and the width 120a of each microcup structure 120 cannot be too large, otherwise the containing structure 12 will be easily damaged. Therefore, the aperture ratio of the accommodating structure 12 of the conventional electrophoretic display 100 is small, or the size of the electrophoretic display 100 is small.

At this time, the charged colored particles 234 will move to the first substrates 222a and the second substrates 224a, and the charged colored particles 234 rotate in different ways, and then present different colors to display certain information . Therefore, the user can view the electrophoretic display 200 from the viewing direction D2 shown in FIG. 2A to interpret the displayed information.

In each microcup structure group 220 of the accommodating structure 22, the first microcup structures 222 are connected to the second microcup structures 224, and are adjacent to the extension surface of the junction C of the first microcup structures 222 through the interior of one of the second microcup structures 224 . In other words, each of the first microcup structures 222 and the directly connected second microcup structures 224 are misaligned and not aligned, so compared with the conventional technology (also refer to FIG. 1A and FIG. 1B ), overall, the accommodation The structural strength of the structure 22 is relatively strong. Therefore, when the size of the electrophoretic display 200 is the same as that of the electrophoretic display 100, the thickness T1 of each partition wall 222b can be smaller, the thickness T2 of each partition wall 224b can be smaller, and the width W1 of each first microcup structure 222 can also be smaller.
