Liquid crystal device and manufacturing method therefor
View Patent ↗The present invention provides a manufacturing method or a structure capable of reducing occurrence of sealing defects and breaking defects by resolving defects in form of a joined area between a sealing material and an anisotropic conductive material. A sealing material ( 2 ) is formed in such a manner as to superimpose ends ( 2 b ) on alignment marks ( 15 ) formed on the surface of a first substrate ( 6 a ), an anisotropic conductive material is formed in such a manner as to superimpose ends 3 b on alignment marks ( 16 ) formed on the surface of a second substrate ( 6 b ), and the sealing material 2 and the anisotropic conductive material ( 3 ) are joined by bonding the first substrate ( 6 a ) and the second substrate ( 6 b ) to form one-piece sealing section ( 4 ).
1. A method for manufacturing a liquid crystal device comprising liquid crystal sealed between a pair of substrates bonded by a sealing section;
wherein one of a sealing material and an anisotropic conductive material is arranged on the surface of one of the substrates;
the other one of the sealing material and the anisotropic conductive material is arranged on the surface of the other one of the substrates;
an end of at least one of the sealing material and the anisotropic conductive material to be joined to the other one is formed to have a width thinner than other portions or formed in a thin wall, wherein the ends formed to have a width thinner than other portions is formed in a shape such that both of an inner edge and an outer edge thereof are retracted from other portions; and
the pair of substrates is bonded to each other so that the end of the sealing material and the end of the anisotropic conductive material are joined to each other, and the sealing section is formed in the shape of surrounding liquid crystal by the sealing material and the anisotropic conductive material joined to each other.
2. The method for manufacturing a liquid crystal device as claimed in claim 1 , wherein the distance between portions of both sides of a joined area between the sealing material and the anisotropic conductive material and an outer edge of a liquid crystal display area formed inside the sealing section is formed longer than the distance between the portions of both sides of the joined area and a substrate outer edge located outside the sealing section; and
an outer edge of the end formed to have a width thinner than the other portions is formed in a flat shape with respect to the other portions, or formed in a shape retracted from the portions of both sides of the joined area.
3. The method for manufacturing a liquid crystal device as claimed in claim 1 , wherein the distance between portions of both sides of a joined area between the sealing material and the anisotropic conductive material and an outer edge of a liquid crystal display area formed inside the sealing section is formed shorter than the distance between the portions of both sides of the joined area and a substrate outer edge located outside the sealing section; and
an inner edge of the end formed to have a width thinner than the other portions is formed in a flat shape with respect to the other portions, or formed in a shape retracted from the portions of both sides of the joined area.
