Apparatus having a plurality of curable resin parts with different hardening state
View Patent ↗There are provided an apparatus and a method of manufacturing the apparatus. The apparatus includes: a plate-shaped base; a cover plate; and a curable resin adhering the plate-shaped base and the cover plate together. At least one of the plate-shaped base and the cover plate includes a light-shielding member covering a peripheral part of the at least one of the plate-shaped base and the cover plate. In an area which is shielded by the light-shielding member, a part of the curable resin at a side of an inner edge of the light shielding member is lower in one of an elastic modulus, a curing degree, and an adhesion strength than another part of the curable resin at a side of an outer edge of the light shielding member.
1. An apparatus comprising:
a plate-shaped base;
a cover plate;
a curable resin located in a gap between the plate-shaped base and the cover plate and adhering the plate-shaped base and the cover plate together; and
a light-shielding member located on a peripheral part of at least one of the plate-shaped base and the cover plate,
wherein the curable resin includes a first curable-resin part, a second curable-resin part, and a third curable-resin part,
the first curable-resin part, the second curable-resin part, and the third curable-resin part are arranged from an outside of the apparatus toward an inside of the apparatus,
the first curable-resin part contacts the second curable-resin part,
the second curable-resin part contacts the third curable-resin part,
the first curable-resin part and the second curable-resin part are shielded by the light-shielding member,
the third curable-resin part is not shielded by the light-shielding member,
the one of an elastic modulus, a degree of cure, and an adhesion strength of the first and second curable-resin part decreases continuously from an outer edge of the light-shielding member to an inner edge of the light-shielding member, and
the one of an elastic modulus, a degree of cure, and an adhesion strength of the third curable-resin part is uniform.
2. The apparatus of claim 1 ,
wherein the elastic modulus of the second curable-resin part is equal to 5 KPa or less.
3. The apparatus of claim 1 ,
wherein the second curable-resin part has the degree of cure of about 60%, and the first curable-resin part has the degree of cure equal to 80% or more.
4. The apparatus of claim 1 ,
wherein the gap is filled with the curable resin up to the end of the plate-shaped base.
5. The apparatus of claim 1 , further comprising a gap-forming member located in the gap between the plate-shaped base and the cover plate.
6. The apparatus of claim 5 ,
wherein the gap-forming member is located at a position between the outer edge and the inner edge of the area in the gap, which is shielded by the light-shielding member, to separate the first curable-resin part and the second curable-resin part from each other.
7. The apparatus of claim 1 ,
wherein the plate-shaped base includes an image display unit or an input unit.
8. The apparatus of claim 7 ,
wherein the plate-shaped base includes an image display unit,
the image display unit includes substrates facing each other, a seal joining the substrates together, and liquid crystal sealed within a space inside the seal,
the second curable-resin part is located in the gap to cover an area from the inner edge of the light-shielding member to an inner edge of the seal, and
the first curable-resin part is located in the gap to cover an area from the inner edge of the seal to the outer edge of the light-shielding member.
9. The apparatus of claim 1 ,
wherein the cover plate includes an input unit, a substrate, or a composite substrate.
10. The apparatus of claim 1 ,
wherein the second curable-resin part is interposed between the first curable-resin part and the third curable-resin part.
11. The apparatus of claim 10 ,
wherein the first curable-resin part includes an end of the curable resin.
12. The apparatus of claim 1 ,
wherein the degree of cure changes step-wise between the first curable-resin part and the second curable-resin part.
