[0099] figure 1 is a diagram showing a structural example of an electrowetting display as an example of the structure of an electrowetting element manufactured by the present invention. in addition, figure 2 It is a figure for explaining the operation concept of an electrowetting display. It should be noted that, in figure 2 In , the diagrams are simplified for the structures of parts that do not need to be explained.
[0100] Such as figure 1 As shown, the electrowetting display 100 has a first substrate 110 and a second substrate 120 , and these substrates 110 , 120 are oppositely arranged with a high surface energy liquid 130 interposed therebetween. The high surface energy liquid 130 is arranged in a region defined by the sealing material 140 provided along the outer circumference of the substrates 110 , 120 . Here, the high surface energy liquid 130 refers to a liquid having relatively higher surface energy than the low surface energy liquid 131 described later. I...

[0149] Next, a second manufacturing method of the electrowetting display 100 described above will be described as a second embodiment of the present invention. Figure 7 It is a figure showing the manufacturing process of this embodiment, and illustration of the common electrode 111 is abbreviate|omitted. However, the same symbols are assigned to the same components as those in the first embodiment, and detailed description thereof will be omitted or simplified.
[0150] In the manufacturing method of this embodiment, first, as image 3 As shown, a second substrate 120 manufactured by a conventional method is prepared, and pixel walls 127 are formed on the second substrate 120 . Next, if Figure 7 As shown in (a), a high-viscosity material 131A composed of a low surface energy liquid 131 whose viscosity has been increased to a viscosity of 1 Pa·s or higher is arranged in each pixel G of the second substrate 120 . Among them, the so-called high-viscosity material 131A includ...

[0201] Next, a third manufacturing method of the electrowetting display 100 described above will be described as a third embodiment of the present invention. Figure 8 It is a figure showing the manufacturing process of this embodiment, and illustration of the common electrode 111 is abbreviate|omitted. Here, the same symbols are assigned to the same components as those in the first embodiment and the second embodiment, and detailed description thereof will be omitted or simplified.
[0202] In the manufacturing method of this embodiment, first, as image 3 As shown, a second substrate 120 manufactured by a conventional method is prepared, and pixel walls 127 are formed on the second substrate 120 . Next, if Figure 8 As shown in (a), a mixed high-viscosity material 132A is arranged in each pixel G of the second substrate 120 .
[0203] The mixed high-viscosity material 132A is composed of a high-surface-energy liquid 130 adjusted to a viscosity of 1 Pa·s or more, a low-sur...
