Display device
A display device includes: an insulating substrate having flexibility and including a bent portion that is bent at 90 degrees or more outside a display area provided with an image display function; and a spacer disposed inside the bent portion and including a curved area around which the bent portion is wrapped and a plane area facing the insulating substrate, wherein the insulating substrate includes a flat portion adjacent to the bent portion and provided so as to face the plane area.
1. A display device comprising:
a flexible substrate including a first portion, a second portion, and a bent portion between the first portion and the second portion, the bent portion bent at 90 degrees or more;
a display area on the first portion; and
a spacer inside the bent portion,
the spacer comprising:
a curved portion along an arc with an axis as a center; and
a projecting portion projecting outward from the arc, and having a first plane portion and a second plane portion, wherein
the first plane portion extends from one end of the arc in a direction tangential to the arc,
the second plane portion extends from another end of the arc in a direction tangential to the arc,
the second plane portion is at an angle of 90 degrees or less with respect to the first plane portion,
the bent portion is in contact with the curved portion,
a part of the first portion is in contact with the first plane portion, and
the first portion and the second portion face each other.
2. The display device according to claim 1 , wherein
the arc is a part of a circle with a diameter larger than a distance between the first portion and the second portion which face each other.
3. The display device according to claim 1 , wherein
the spacer has a groove in the curved portion so as to extend in a direction parallel to the axis, and
the bent portion and the spacer are bonded with an adhesive member in the groove.
4. The display device according to claim 1 , wherein
the spacer has a groove in the curved portion so as to extend along the arc, and
the bent portion and the spacer are bonded with an adhesive member in the groove.
5. The display device according to claim 1 , wherein
the bent portion has a bent angle of 180 degrees or more.
6. The display device according to claim 1 , wherein
the flexible substrate includes a folded-back portion, folded back through the bent portion, on a side opposite to a viewing side of the display area, and
the folded-back portion includes the second portion and is bonded, at an inner surface thereof, to the side opposite to the viewing side.
7. The display device according to claim 1 , wherein
the bent portion includes two bent portions that are arranged so as to hold the first portion therebetween,
the second portion includes two second portions that are arranged so as to hold the two bent portions therebetween in a developed view of the flexible substrate, and
each of the two bent portions is between the first portion and a corresponding one of the two second portions.
8. The display device according to claim 1 , further comprising a flexible printed circuit board, wherein
the flexible printed circuit board is mounted on an end part of the flexible substrate.
9. The display device according to claim 6 , further comprising a flexible printed circuit board, wherein
the flexible printed circuit board is mounted at the folded-back portion.
