Abstract

A display device includes a first substrate, a second substrate arranged to face the first substrate, and a seal member arranged to bond the first substrate and the second substrate to each other with a display medium layer enclosed between the first substrate and the second substrate. At least one of the first substrate and the second substrate has a layered structure of a reinforcing layer and one or more layers having a lower strength than that of the reinforcing layer, and at least a portion of the seal member is bonded directly to the reinforcing layer.

Claims

1. A display device comprising:

a first substrate;

a second substrate arranged to face the first substrate; and

a seal member arranged to bond the first substrate and the second substrate to each other with a display medium layer enclosed between the first substrate and the second substrate;

wherein

at least one of the first substrate and the second substrate has a layered structure of a reinforcing layer and one or more layers having a lower strength than that of the reinforcing layer, an opening is formed in the one or more layers so as to expose a portion of the reinforcing layer, and at least a portion of the seal member is bonded directly to the reinforcing layer in the opening.

2. The display device according to claim 1, wherein the seal member has an approximately frame shape when viewed from a normal direction to the first substrate or the second substrate, and the opening has a ring shape extending along a circumferential direction of the seal member.

3. The display device according to claim 2, wherein a plurality of ring-shaped openings are coaxially arranged.

4. The display device according to claim 1, wherein the seal member has an approximately frame shape when viewed from a normal direction to the first substrate or the second substrate, and the opening has a staggered pattern when viewed from the normal direction to the first substrate or the second substrate.

5. The display device according to claim 1, wherein the seal member has an approximately rectangular frame shape when viewed from a normal direction to the first substrate or the second substrate, and the opening is formed in four corner regions of the seal member when viewed from the normal direction to the first substrate or the second substrate.

6. The display device according to claim 1, wherein the opening extends through the reinforcing layer.

7. The display device according to claim 1, wherein, of the first substrate and the second substrate, a substrate having the reinforcing layer is a flexible substrate.

8. The display device according to claim 1, wherein the reinforcing layer is a layer made of a plurality of fiber bodies.

9. The display device according to claim 8, wherein the fiber bodies are made of glass fibers.

10. The display device according to claim 8, wherein the fiber bodies are made of aromatic polyamide resin fibers.

11. The display device according to claim 1, wherein each of the first substrate and the second substrate has the reinforcing layer.

12. The display device according to claim 1, wherein the reinforcing layer has a smaller linear thermal expansion coefficient than that of the one or more layers.

13. The display device according to claim 1, wherein the display medium layer is a liquid crystal layer.
