Display device
According to one embodiment, a display device includes a first substrate including a first insulating substrate, a second substrate including a second insulating substrate and opposing the first substrate, and an adhesive layer which attaches the first substrate and the second substrate together. The adhesive layer includes a first portion extending in a first direction. The first portion includes a first end portion and a second end portion, each extending in the first direction. The second substrate includes a third end portion located between the first end portion and the second end portion and extending in the first direction. The first substrate and the second substrate are bent in a position overlapping the first portion.
1. A display device comprising:
a first substrate comprising a first insulating substrate;
a second substrate comprising a second insulating substrate and opposing the first substrate;
a liquid crystal layer held between the first substrate and the second substrate; and
an adhesive layer which attaches the first substrate and the second substrate together,
the adhesive layer comprising a first portion extending in a first direction,
the first portion comprising a first end portion and a second end portion, each extending in the first direction,
the second substrate comprising a third end portion located between the first end portion and the second end portion and extending in the first direction,
the third end portion of the second substrate overlapping the first portion in a plan view,
a part of the first portion extending outside the third end portion of the second substrate in a plan view, and
the first substrate and the second substrate being bent in a position overlapping the first portion.
2. The display devices of claim 1 , wherein
the first substrate and the second substrate are bent in a position between the second end portion and the third end portion.
3. The display device of claim 1 , wherein
the first substrate comprises a fourth end portion extending in the first direction, and comprises a mounting portion between the first end portion and the fourth end portion.
4. The display device of claim 1 , wherein
the first insulating substrate and the second insulating substrate are each formed from a polyimide.
5. The display device of claim 1 , wherein
the first portion requires energy higher than that of the second substrate, to be decomposed by light of a wavelength shorter than 350 nm.
6. The display device of claim 1 , wherein
the adhesive layer is formed from an epoxy acrylate.
7. The display device of claim 1 , wherein
the adhesive layer comprises a second portion crossing the first portion and extending along a second direction crossing the first direction, and
a first width of the first portion is greater than a second width of the second portion.
8. The display device of claim 1 , wherein
the first substrate comprises a signal wiring line extending in a second direction crossing the first direction in a position overlapping the first portion.
9. The display device of claim 3 , further comprising:
a display area surrounded by the adhesive layer; and
a wiring substrate provided on the mounting portion, wherein
the first substrate and the second substrate are bent such that the wiring substrate opposes the display area.
10. The display device of claim 1 , further comprising:
a support member adhered to the first substrate,
wherein
the first substrate and the second substrate are bent to interpose the support member.
11. The display device of claim 1 , wherein the first insulating substrate and the second insulating substrate are different from each other in thickness.
