而采用中框分段设计， 即采用分段件组合实现中框的功能， 这样又会导致 分段件之间的空隙会漏光， 光学品味下降。

优选的， 所述遮光层环绕整个光学膜片的边缘， 覆盖整个非显示区。 这样 可以最大限度地遮盖中框表面， 防漏光效果更好。
优选的， 所述光学膜片有多层， 其中一层的非显示区表面设有所述遮光层。 光学膜片可以采用多层结构， 只需要在其中一层设置遮光层即可， 有利于筒化 生产工序， 节约成本。 优选的， 所述光学膜片的非显示区的表面覆盖有油墨层， 形成所述遮光层。 此为一种具体的遮光层材料， 油墨遮光效果好， 粘附性强， 方便加工。
一种液晶显示装置， 包括光学膜片， 所述光学膜片包括中间部分的显示区 和边缘部分的非显示区， 所述非显示区在所述液晶显示装置的漏光处设有遮光 层。
优选的， 所述液晶显示装置还包括中框， 所述中框表面铺设有光学膜片， 所述中框由多条中框构造单元拼接而成， 所述光学膜片的非显示区至少在中框 构造单元的拼接处设有遮光层。 此为一种带拼接式中框的液晶显示装置。
优选的， 所述中框由多个框边单元和四个框角单元拼接形成， 所述光学膜 片的非显示区在中框构造单元的拼接处设有遮光层。 此为一种具体的中框拼接 形式， 中框的拼接处漏光最严重， 因此有针对性地在拼接处设置遮光层， 可以 降低成本。
优选的， 所述中框由多个框边单元拼接形成， 所述光学膜片的非显示区在 所述中框构造单元的拼接处以及所述中框的四个角位置对应设有遮光层。 此为 另一种具体的中框拼接形式， 中框的拼接处漏光最严重， 因此有针对性地在拼 接处设置遮光层， 可以降低成本。
优选的， 所述遮光层环绕整个光学膜片的边缘， 覆盖整个非显示区。 样可 以最大限度地遮盖中框表面， 防漏光效果更好。
发明人研究发现， 光学膜片的非显示区刚好能覆盖住中框表面， 因此可以 就地取材， 直接在光学膜片的非显示区设置遮光层， 防止中框在拼接处漏光。 另外， 本发明利用现有的材料实现中框的遮光， 筒单实用， 成本低。

【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
一种液晶显示装置， 包括背光模组和液晶面板， 背光模组的出光面设有光 学膜片。 如图 1和 2所示， 光学膜片包括中间部分的显示区和边缘部分的非显 示区， 非显示区在所述液晶显示装置的漏光处设有遮光层。 由于光学膜片位于 背光模组的出光面， 因此无论液晶显示装置有无中框， 都能实现遮光效果， 不 过一般的液晶显示装置都设有中框， 因此本实施方式选用带拼接式中框的液晶 显示装置为例进行说明。 该液晶显示装置包括中框， 中框表面铺设有光学膜片， 中框由多条中框构造单元拼接而成， 光学膜片包括中间部分的显示区和边缘部 分的非显示区， 非显示区设有遮光层（如图 1、 2所示）。
发明人研究发现， 光学膜片的非显示区刚好能覆盖住中框表面， 因此可以 就地取材， 直接在光学膜片的非显示区设置遮光层， 防止中框在拼接处漏光。 另外， 本发明利用现有的材料实现中框的遮光， 筒单实用， 成本低。 下面结合 不同种类的拼接式中框的液晶显示装置， 进一步产生本发明的应用。
实施例一
如图 3所示， 一种液晶显示装置， 包括中框 100, 中框 100表面铺设有光学 膜片 200, 中框 100由多个框边单元 120和四个框角单元 110拼接形成， 光学膜 片 200的非显示区在中框构造单元的拼接处设有遮光层 210,光学膜片 200可以 是单层结构， 也可以采用多层结构， 对于多层结构的光学膜片， 只需要在其中 一层的表面设置遮光层即可。 中框 100 的拼接处漏光最严重， 因此有针对性地 在拼接处设置遮光层 210, 可以降低成本。
当然， 也可以如图 4所示， 遮光层 210可以环绕整个光学膜片 200的边缘， 覆盖整个非显示区， 这样可以最大限度地遮盖中框 100表面， 防漏光效果更好。
遮光层 210可以采用油墨等可用于遮光的材料制成， 比如， 可以在光学膜 片 200的非显示区的表面覆盖油墨层， 形成遮光层 210。 油墨遮光效果好， 粘附 性强， 方便加工。
实施例二
如图 5所示， 一种液晶显示装置， 包括中框， 中框由多个框边单元 120拼 接形成， 光学膜片 200 的非显示区在中框构造单元的拼接处以及中框的四个角 位置对应设有遮光层 210,光学膜片 200可以是单层结构，也可以采用多层结构， 对于多层结构的光学膜片， 只需要在其中一层的表面设置遮光层即可。 中框的 拼接处漏光最严重， 因此有针对性地在拼接处设置遮光层 210, 可以降低成本。
当然， 也可以如图 6所示， 遮光层 210可以环绕整个光学膜片 200的边缘， 覆盖整个非显示区， 这样可以最大限度地遮盖中框表面， 防漏光效果更好。
遮光层 210可以采用油墨等可用于遮光的材料制成， 比如， 可以在光学膜 片 200的非显示区的表面覆盖油墨层， 形成遮光层 210。 油墨遮光效果好， 粘附 性强， 方便加工。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
