Electrophoretic display sheet, electrophoretic display device, and electronic apparatus
View Patent ↗In at least one embodiment of the disclosure, an electrophoretic display sheet includes an electrophoretic display layer and a substrate provided with the electrophoretic display layer. An end portion of the substrate includes a chamfered edge. The electrophoretic sheet may be attached to a driving substrate.
1. An electrophoretic display sheet, comprising:
an electrophoretic display layer;
a substrate having a first portion, a second portion, and a third portion, the second portion being positioned between the first portion and the third portion, the first portion having a uniform thickness and being positioned overlapping with the electrophoretic display layer, the second portion having a uniform thickness and a curved surface and extending beyond the electrophoretic display layer, and the third portion having a chamfered edge for making surface contact with a driving substrate for an electrophoretic display device; and
an electrode being positioned between the electrophoretic display layer and the substrate.
2. The electrophoretic display sheet according to claim 1 , the third portion of the substrate including an elastic member.
3. The electrophoretic display sheet according to claim 1 ,
the chamfered edge being on a side of the substrate facing the electrode.
4. The electrophoretic display sheet according to claim 1 , the third portion of the substrate further including another chamfered edge.
5. The electrophoretic display sheet according to claim 1 , the curved surface having a radius of curvature that is equal to or greater than one tenth of the thickness of the substrate.
6. An electrophoretic display device, comprising:
the electrophoretic display sheet according to claim 1 ; and
the driving substrate.
7. The electrophoretic display device according to claim 6 , the driving substrate including a first portion having a transistor and a second portion surrounding the first portion, the third portion of the substrate being configured to make contact with the second portion of the driving substrate.
