no. 1 Embodiment approach

[0088]

[0089] figure 1 It is a perspective view of an electronic device equipped with an electrophoretic device. As follows, while referring to figure 1 The structure of the electronic device will be described.

[0090] Such as figure 1 As shown, the electronic device 100 includes the electrophoretic device 10 and an interface for operating the electronic device 100 . The so-called interface is specifically the operation unit 110 and includes switches and the like.

[0091] The electrophoretic device 10 is a display module having a display area E. As shown in FIG. The display area E includes a plurality of pixels, and an image is displayed on the display area E by electrically controlling these pixels.

[0092] In addition, the electronic device 100 including the electrophoretic device 10 can also be applied to electronic paper (EPD: Electronic Paper Display), watches, wearable devices, and the like.

[0165]

[0166] Figure 14 It is a schematic plan view showing the structure of the electrophoretic device. Figure 15 is along Figure 14 A schematic cross-sectional view of the line A-A' of the electrophoretic device shown. As follows, while referring to Figure 14 as well as Figure 15 The structure of the electrophoresis device will be described.

[0167] Such as Figure 14 as well as Figure 15 As shown, the electrophoretic device 210 has an element substrate 251 as a first substrate, a counter substrate 252 as a second substrate, and an electrophoretic layer 233 . A pixel electrode 221 is arranged for each pixel 211 on the first base material 231 including, for example, a light-transmitting glass substrate constituting the element substrate 251 .

[0168] If described in detail, as Figure 14 as well as Figure 15 As shown, the pixels 211 (pixel electrodes 221 ) are formed, for example, in a matrix when viewed from above. As a material of the pixel electrode ...

Abstract

An electrophoretic apparatus includes: an electrophoretic layer that is disposed between an element substrate and a counter substrate, and has a dispersion medium in which electrophoretic particles are dispersed; a partition wall that is disposed to separate the electrophoretic layer into a plurality of cells; a seal material that bonds the element substrate and the counter substrate, and is disposed so as to surround the electrophoretic layer; and a sealing film that is disposed at least between the partition wall and the counter substrate, and has no adhesive material, in which a top section of the partition wall is disposed in the sealing film.

Description

technical field [0001] The present invention relates to an electrophoretic device, a method for manufacturing the electrophoretic device, and electronic equipment. Background technique [0002] In the above-mentioned electrophoretic device, an image is formed in the display region by applying a voltage between the pixel electrode and the common electrode facing each other across the electrophoretic material to move electrophoretic particles such as charged black particles and / or white particles in space. As an electrophoretic device, for example, a pair of substrates is divided into a plurality of spaces by a partition wall, and an electrophoretic dispersion liquid containing electrophoretic particles and a dispersion liquid is enclosed in each space. [0003] Regarding the electrophoretic device, it is disclosed that, for example, as described in Patent Document 1, in order to seal the electrophoretic dispersion liquid (electrophoretic ink) in the cell without gaps, the top...
