Problems solved by technology

[0007] However, in this production method, although the sealing liquid is coated or sprayed and then solidified, there is a problem that when the specific gravity of the electrophoretic fluid is lower than the specific gravity of the sealing composition, the sealing liquid is solidified. before sinking from the surface, making it impossible to seal electrophoretic fluids, etc.

Abstract

The purpose of the present invention is to provide the following: a low-cost, high-quality electrophoretic display sheet that is highly durable, exhibits excellent display characteristics, and can be produced with high yield; and an electrophoretic display medium using said electrophoretic display sheet. This electrophoretic display sheet (A) can be obtained, for example, by: using diving walls (15) comprising an insulating material to form a cell structure (20) on a light-transmitting electrode surface (11) formed on a light-transmitting substrate material (10); filling said cell structure (20) with an electrophoretic ink (25); and bonding a film (35) on which an adhesive sealing layer or pressure-sensitive adhesive sealing layer (30) is formed to the top surface of the cell structure (20).

Description

technical field [0001] The present invention relates to an electrophoretic display panel and an electrophoretic display medium using the electrophoretic display panel. Background technique [0002] In recent years, demands for lower power consumption, thinner, lighter, and more flexible displays have increased, and electronic paper, one of them, has attracted attention. An electrophoretic display device using electrophoretic ink or the like is known as one of such electronic papers. [0003] Generally, an electrophoretic display device has a structure in which two electrode substrates including at least one transparent electrode substrate are arranged facing each other, and electrophoretic ink is provided between the facing electrodes to form a display panel. Then, content can be displayed on the transparent electrode surface by applying an electric field to the display panel. [0004] The electrophoretic display device is a display medium that can obtain the desired displ...
