Display device and manufacturing method thereof
A display device includes a plurality of layers stacked such that outer edges thereof coincide with each other at both ends in at least one of a first direction and a second direction that are orthogonal to each other and each layer including holes communicating in the stacking direction at a plurality of positions, and a resin continuously filled in the holes over the entirety of the plurality of layers. The plurality of layers include a display panel including a display area. The display panel includes the corresponding holes outside the display area. The holes of the plurality of layers are displaced in a plan view, as compared with the matching accuracy of the outer edges.
1. A display device comprising:
a plurality of layers stacked such that outer edges thereof coincide with each other at both ends in at least one of a first direction and a second direction that are orthogonal to each other, and each layer including holes communicating with each other in the stacking direction at a plurality of positions; and
a resin continuously filled in the holes over the entirety of the plurality of layers, wherein
the plurality of layers include a display panel including a display area,
the display panel includes the corresponding holes outside the display area, and
the holes in the plurality of layers are displaced in a plan view, as compared with the matching accuracy of the outer edges.
2. The display device according to claim 1 , wherein
the uppermost layer or the lowermost layer of the plurality of layers includes a concave portion as the hole, and
the plurality of layers except for the uppermost layer or the lowermost layer include through-holes as the holes.
3. The display device according to claim 2 , wherein
the uppermost layer or the lowermost layer is a cover glass or a housing.
4. The display device according to claim 1 , wherein
each of the plurality of layers includes a through-hole as the hole.
5. The display device according to claim 1 , wherein
the plurality of layers include at least one of a support film, a cushion sheet, and a heat equalizing sheet.
6. The display device according to claim 1 , wherein
the outer edges of the plurality of layers coincide with each other at both ends in only one of the first direction and the second direction.
7. The display device according to claim 1 , wherein
the holes in the plurality of layers are displaced in a plan view in at least one of the center and the inner surface.
8. A manufacturing method of a display device comprising:
stacking a plurality of layers such that outer edges thereof coincide with each other at both ends in at least one of a first direction and a second direction that are orthogonal to each other, and holes at a plurality of positions included in each layer communicate with each other in the stacking direction;
continuously filling the holes with a resin over the entirety of the plurality of layers; and
curing the resin, wherein
the plurality of layers include a display panel including a display area,
the display panel includes the corresponding holes outside the display area, and
the holes of the plurality of layers are displaced in a plan view, as compared with the matching accuracy of the outer edges.
9. The manufacturing method of a display device according to claim 8 , wherein
the resin is in a liquid, gel, or paste form in the step of filling the resin.
