Structure of LCD manufactured by one-drop fill technology including a substrate with transparent conductive patterns
View Patent ↗A structure of liquid crystal display and manufacture method thereof are described. The liquid crystal display is manufactured by a one drop fill process. The display comprises a first substrate, a second substrate, a conductive pattern layer, a black matrix layer, a liquid crystal layer and an ultraviolet-type seal. The metal pattern layer is made of indium tin oxide and formed on the first substrate. Therefore, the metal pattern layer is a transparent layer allowing the ultraviolet light to pass through. The ultraviolet-type seal is pre-cured by the ultraviolet light from the first substrate direction to the seal, and then cured by a heating process. Hence, the liquid crystal pollution problem is reduced.

spreading an ultraviolet-type seal on the first substrate;
dropping a liquid crystal material on the first substrate;
gluing the first substrate and the second substrate in a vacuum chamber;
exposing the seal to an ultraviolet ray from the first substrate to pre-harden the seal for a predetermined period; and
heating the seal.
