Display device with overlapping substrate
A display device includes a substrate including a peripheral region folded back to face a rear surface of the substrate, and a counter region facing the peripheral region; and a filling member held between the peripheral region and the counter region. The substrate is folded such that the display device includes a first overlapping portion where a part of the peripheral region is bonded with the counter region with an adhesive material being provided therebetween; a second overlapping portion where a part of the peripheral region is in direct contact with the filling member; and a third overlapping portion where a part of the peripheral region is bonded with the filling member with an adhesive material being provided therebetween.
1. A display device, comprising:
a substrate having a front surface at which pixels are provided and a rear surface opposite to the front surface, the substrate including a peripheral region located along a first side of the substrate and folded back to face the rear surface, and a counter region facing the peripheral region;
a filling member held between the peripheral region and the counter region;
a first overlapping portion of the substrate where a part of the peripheral region is bonded with the counter region with an adhesive material being provided therebetween;
a second overlapping portion of the substrate where a part of the peripheral region is in contact with the filling member; and
a third overlapping portion of the substrate where a part of the peripheral region is bonded with the filling member with the adhesive material being provided therebetween,
wherein the first overlapping portion is located along the first side, the third overlapping portion is located further inward than the first overlapping portion from the first side of the substrate, the second overlapping portion is located between the first overlapping portion and the third overlapping portion, and the first overlapping portion of the substrate and the filling member do not overlap.
2. The display device according to claim 1 , wherein:
the peripheral region includes a curved portion; and
the curved portion is contacting with the filling member.
3. The display device according to claim 2 , wherein the peripheral region includes a non-curved portion between the curved portion and the first side.
4. The display device according to claim 3 , wherein the non-curved portion has a driving circuit provided therein.
5. The display device according to claim 1 , wherein:
the peripheral region includes a curved portion; and
a space is not provided between the curved portion and the filling member.
6. The display device according to claim 1 , wherein:
the filling member is made gradually thinner from the second overlapping portion toward the first overlapping portion.
7. The display device according to claim 1 , further comprising a protective film provided on the rear surface of the substrate;
wherein the adhesive material is provided on the protective film.
8. The display device according to claim 7 , wherein:
the peripheral region includes a curved portion; and
the protective film includes a portion in contact with the rear surface of the curved portion.
9. The display device according to claim 8 , wherein:
the peripheral region includes a non-curved portion between the curved portion and the first side; and
the protective film includes a portion in contact with the non-curved portion.
10. The display device according to claim 7 , wherein an end of the protective film is located on the counter region.
11. The display device according to claim 1 , wherein:
the adhesive material is formed of a pressure-sensitive adhesive tape; and
the pressure-sensitive adhesive tape is located along the entirety of the first side.
12. The display device according to claim 1 , wherein:
the adhesive material is formed of a pressure-sensitive adhesive tape; and
the pressure-sensitive adhesive tape is located along a part of the first side.
13. The display device according to claim 1 , wherein the filling member is formed of a resin.
14. The display device according to claim 1 , wherein the substrate is formed of a resin.
15. The display device according to claim 1 , further comprising a counter substrate facing the substrate, wherein:
the counter substrate covers a part of the front surface of the substrate; and
the front surface of the peripheral region is not covered with the counter substrate.
