Electronic device
According to one embodiment, an electronic device includes a first substrate, a second substrate opposing the first substrate, a pressure sensitive layer disposed between the first substrate and the second substrate, and an elastic member that covers the first substrate, the second substrate and the pressure sensitive layer. The first and second substrates include a first and second insulating substrates formed into a mesh-like shape. The elastic member includes slits that are formed around a first island-shaped portion of the first insulating substrate and a second island-shaped portion of the second insulating substrate. The slits open when the elastic member is expanded.
1. An electronic device comprising: a first substrate; a second substrate opposing the first substrate; a pressure sensitive layer disposed between the first substrate and the second substrate; and an elastic member that covers the first substrate, the second substrate and the pressure sensitive layer, wherein the first substrate comprises: a first insulating substrate including a plurality of first island-shaped portions and a plurality of first strip-shaped portions each connecting a respective adjacent pair of first island-shaped portions, and formed into a mesh-like shape; a wiring line disposed on the first strip-shaped portion; and a sensor electrode disposed on the first island-shaped portion and electrically connected to the wiring line, the second substrate comprises: a second insulating substrate including a plurality of second island-shaped portions and a plurality of second strip-shaped portions each connecting a respective adjacent pair of second island-shaped portions, and formed into a mesh-like shape; and a common electrode disposed under the second island-shaped portions and the second strip-shaped portions, and formed in a mesh-like shape, and the elastic member includes slits that are formed around the first island-shaped portion and the second island-shaped portion and that open when the elastic member is expanded, wherein the first island-shaped portion and the second island-shaped portion are each formed in a rectangular shape and respectively overlap each other in plan view, and the slits are each formed at a predetermined distance from a respective side of each of the first island-shaped portion and the second island-shaped portion, into a straight line along each respective side thereof.
2. The electronic device of claim 1 , wherein
the slits are each formed at a predetermined distance from a respective end portion of each of the first island-shaped portion and the second island-shaped portion.
3. The electronic device of claim 2 , wherein
the slits are each formed at such a distance away from the respective end portion of each of the first island-shaped portion and the second island-shaped portion by a distance that the slits are not brought into contact with the first island-shaped portion and the second island-shaped portion when the slits are opened during expansion of the elastic member.
4. The electronic device of claim 3 , wherein
the slits are each formed at a distance of at least 10 μm from the respective end portion of each of the first island-shaped portion and the second island-shaped portion.
5. The electronic device of claim 1 , further comprising an adhesive layer disposed at a position overlapping an outer periphery of the first island-shaped portion and the second island-shaped portion in plan view, which bonds the first substrate and the second substrate to each other.
