所述像素区 203 内设置有阵列分布的若干薄膜晶体管，所述薄膜晶体管包括有栅极、源极以及漏极；所述第一区域还包括若干条数据线以及若干条扫描线，一条所述扫描线与一条所述数据线垂直交错形成一像素单元，所述像素单元内形成有像素电极，一所述像素单元内设置一所述薄膜晶体管；所述扫描线连接位于同一行的各所述薄膜晶体管的栅极，所述数据线连接位于同一列的各所述薄膜晶体管的源极，所述像素电极连接相应的所述薄膜晶体管的漏极。
所述框胶涂布区 205 内设置有第一金属走线 206 、覆盖所述第一框胶涂布区 205 及所述第一金属走线 206 的绝缘层，以及设置于所述绝缘层表面的第二金属走线 207 ，所述绝缘层上开设有过孔 208 ，所述第一金属走线 206 与所述第二金属走线 207 通过所述过孔 208 连接；其中，所述第一金属走线 206 为金属跨接线，所述第一金属走线 206 的输入端连接所述第二金属走线 207 ，所述第二金属走线 207 为功能走线，例如时钟信号电路、电源电路等。
所述 GOA 电路区 204 内设置有 GOA 走线，所述第一金属走线 206 的输出端连接所述 GOA 走线。
所述第一金属走线 206 与所述第二金属走线 207 制备于所述阵列基板 202 的不同膜层，所述第一金属走线 206 上表面制备有第一绝缘层 209 ，所述第二金属走线 207 与所述第一金属走线 206 之间制备有第二绝缘层 210 ，所述第一金属走线 206 与所述第二金属通过过孔 208 连接；所述过孔 208 包括贯穿于所述第一绝缘层 209 的第一孔洞 211 ，以露出所述第一金属走线 206 ，以及贯穿于所述第二绝缘层 210 的第二孔洞 212 ，以露出所述第二金属走线 207 ，所述第一孔洞 211 的表面至所述第二孔洞 212 的表面制备透明金属层 213 ，以实现所述第一金属走线 206 与所述第二金属走线 207 的连通。
所述框胶涂布区 205 内还设置有冗余间隔件 214 ，所述冗余间隔件 214 覆盖相应的所述过孔 208 表面，以将框胶 215 与位于所述框胶 215 底部的所述过孔 208 进行隔绝，从而避免在高温环境下，所述框胶 215 吸收水汽，水汽浸入金属层而腐蚀金属层。
所述冗余间隔件 214 的形状接近长方形，每一所述冗余间隔件 214 覆盖有至少两个所述过孔 208 。
由于所述冗余间隔件 214 具有一定厚度，为了保证所述阵列基板 202 与所述彩膜基板 201 之间的间隙厚度均匀，需要减小所述框胶 215 的厚度，但是，较薄的框胶 215 存在粘接不牢以及框胶 215 脱落的风险；因此，将所述冗余间隔件 214 的厚度，将所述冗余间隔件 214 表面所处高度设置为低于所述主间隔件表面的高度， 从而避免上述风险。
所述冗余间隔件 214 与所述主间隔件均采用光阻材料制备，从而，所述冗余间隔件 214 与所述主间隔件可同时制备于所述阵列基板 202 表面，节省制程；其中，为了使所述冗余间隔件 214 的厚度尽可能减小，对应所述冗余间隔件 214 的光罩使用半色调光罩，所述光罩表面设置有狭缝；所述冗余间隔件 214 采用负向感光材料，负向感光材料的照到光的部分不会溶于光阻显影液，而没有照到光的部分会溶于光阻显影液。
采用设置有狭缝的半色调光罩形成的所述冗余间隔件 214 ，表面形成有至少两个条形凹部；所述条形凹部用以锁存涂布于所述冗余间隔件 214 表面的所述框胶 215 ，减小所述框胶 215 的流动性；例如，所述条形凹部与所述冗余间隔件 214 的长边相平行；又如，所述条形凹部与所述冗余间隔件 214 的短边相平行。
如图 3 所示，本发明提供的液晶显示面板的框胶涂布区 301 ；包括有第一金属走线 302 、第二金属走线 303 以及 冗余间隔件 304 。
所述第一金属走线 302 与所述第二金属走线 303 之间设置有绝缘层，所述绝缘层上设置有过孔，所述第一金属走线 302 与所述第二金属走线 303 通过所述过孔连接；所述第一金属走线 302 的输入端连接所述第二金属走线 303 ，所述第一金属走线 302 的输出端连接连接 GOA 走线。
所述冗余间隔件 304 覆盖所述过孔。
所述冗余间隔件 304 表面形成有条形凹部 305 ，其中，所述条形凹部 305 与所述冗余间隔件 304 的长边相平行。
如图 4 所示，本发明提供的液晶显示面板的框胶涂布区 401 ；包括有第一金属走线 402 、第二金属走线 403 以及 冗余间隔件 404 。
其中，与图 3 所示的液晶显示面板的区别在于，所述冗余间隔件 404 表面的条形凹部 405 与所述冗余间隔件 404 的短边相平行。
如图 5 所示，依据本发明上述目的，提出一种液晶显示面板制备方法，所述方法包括：
步骤 S10 ，提供阵列基板，所述阵列基板表面定义有像素区和位于所述像素区***的框胶涂布区。
步骤 S20 ，在所述框胶涂布区设置第一金属走线。
步骤 S30 ，在所述框胶涂布区设置绝缘层，并在所述绝缘层上开设过孔，所述绝缘层覆盖所述第一金属走线。
步骤 S40 ，在所述绝缘层上设置第二金属走线，并使得所述第二金属走线与所述第一金属走线通过所述过孔连接。
步骤 S50 ，在所述过孔表面设置冗余间隔件。
步骤 S60 ，在所述冗余间隔件表面设置框胶。
步骤 S70 ，提供彩膜基板，将所述彩膜基板与所述阵列基板相对设置，并使得所述彩膜基板与所述阵列基板通过所述框胶粘接。
本发明的有益效果为： 相较于现有的液晶显示面板，本发明提供的液晶显示面板，通过在框胶涂布区表面与过孔之间设置间隔层，以保护过孔免受水汽腐蚀，保证过孔实现正常的线路连接功能；解决了现有的 液晶显示面板，由于阵列基板的框胶涂布区设置有框胶，框胶覆盖有部分用以实现功能信号线与 GOA 线路连接的过孔，框胶吸收水汽而导致所接触的过孔被腐蚀，进而影响显示 的技术问题 。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
