在本发明的实施例提供的阵列基板中, 通过使阵列基板的村底基板形成 有凹槽, 并将第一电极层设置在凹槽内, 第二电极层设置在凹槽外, 这样利 用村底基板上的凹槽, 可以精确地保证这两个电极层之间的零重叠, 降低制 作成本和制作工艺的难度。
优选地, 村底基板上的凹槽 110可以是等间距的。
优选地, 凹槽 110的深度可以大于第一电极层的厚度。
优选地, 如图 2所示, 每个凹槽内都可以设置有第一电极条 120, 每个 槽外都可以设置有第二电极条 130。

在本发明实施例提供的阵列基板中, 第一电极层和第二电极层中的一个 电极层要作为像素电极而与漏极连接, 与漏极连接的电极层可以是第一电极 层, 也可以是第二电极层。 这里需要说明的是, 无论第一电极层还是第二电 极层, 只要与公共电极线电连接的电极层就用作公共电极, 与薄膜晶体管的 漏极电连接的电极层就用作像素电极。
可选地, 第一电极层可以与薄膜晶体管的漏极连接, 即第一电极层为像 素电极, 第二电极层为公共电极, 此时可以有以下两种情况:
一种情况为: 第一电极层通过栅绝缘层中的过孔与漏极连接。 在此种情 况下, 在阵列基板上先形成第一电极层再形成薄膜晶体管, 然后形成钝化层 和第二电极层。 第一电极层与第二电极层之间可以设置有栅绝缘层。 此时, 栅绝缘层可以位于第一电极层上方, 在栅绝缘层中形成过孔, 栅绝缘层中的 过孔在第一电极层的上方, 漏极可以通过栅绝缘层中的过孔与第一电极层连 接。 另一种情况为: 第一电极层直接连接到漏极。 在此种情况下, 在阵列基 板上先形成薄膜晶体管, 再依次形成第一电极层、 钝化层和第二电极层, 第 一电极层与第二电极层之间可以设置有钝化层。 此时, 第一电极层位于栅绝 缘层的上方, 第一电极层与漏极之间没有其他层级结构, 第一电极层可以直 接搭接在漏极上。
可选地, 也可以是第二电极层与薄膜晶体管的漏极连接, 即第二电极层 为像素电极, 第一电极层为公共电极, 此时可以有以下两种情况:
一种情况为: 第二电极层可以通过钝化层中的过孔与漏极连接。 在此种 情况下, 在阵列基板上先形成钝化层然后再形成第二电极层, 第二电极层位 于钝化层上方, 钝化层中的过孔在漏极的上方, 第二电极层可以通过钝化层 中的过孔与第二电极层连接。
另一种情况为: 第二电极层可以直接连接到漏极, 此种情况下, 在阵列 基板上先形成第一电极层然后再形成薄膜晶体管, 然后依次形成第二电极层 和钝化层, 第二电极层位于钝化层下方, 第二电极层与漏极之间没有其他层 级结构, 第二电极层可以直接搭接在漏极上。

55、 进行光刻胶剥离工艺以将第一光刻胶图案剥离, 形成如图 7所示的 村底基板。
56、 在形成有第一电极层的村底基板上形成绝缘层, 然后在形成有绝缘 层的村底基板上涂敷第二光刻胶 13b, 形成如图 8所示的基板。 这里需要说 明的是, 绝缘层可以包括栅绝缘层和钝化层中的至少一个。 如图 8所示, 由 于村底基板具有凹槽, 使得在绝缘层中形成与村底基板中的凹槽相对应的凹 槽。
57、 对第二光刻胶 13b进行灰化处理以形成如图 9所示的第二光刻胶图 案 13c, 第二光刻胶图案 13c只覆盖绝缘层中的凹槽的底部。
58、如图 10所示,在形成有第二光刻胶图案 13c的村底基板上形成第二 透明导电薄膜 13a。

所形成的第一电极层可以与薄膜晶体管的漏极连接, 或者所形成的第二 电极层可以与薄膜晶体管的漏极连接。 这里需要说明的是, 无论第一电极层 还是第二电极层, 只要与公共电极线电连接的电极层就用作公共电极, 与薄 膜晶体管的漏极电连接的电极层就用作像素电极。
