Description

一种液晶显示面板及其制造方法
【技术领域】
本发明涉及液晶显示面板，具体而言涉及一种液晶显示面板及其制造方法。
【背景技术】
随着高科技的发展，视频产品，特别是数字化的视频或影像装置已经成为一般生活中所常见的产品。这些数字化的视频或影像装置中，显示器是一个重要组件，用来显示相关信息。使用者可由显示器读取信息，进而控制装置的运作。
液晶显示面板作为液晶显示器的主要元件，其主要包含彩色滤光片基板（CF基板）和薄膜晶体管基板（TFT基板）。两片基板的相对内侧设置透明电极，且两片基板之间滴设有一层液晶分子。液晶显示面板是通过电场对液晶分子取向的控制，改变光的偏振状态，并藉由偏光板实现光线的穿透与阻挡，从而实现显示的目的。
CF基板和TFT基板一般通过辐射固化剂（框胶）进行对组。辐射固化剂一般由亚克力、环氧树脂、光起始剂等组成，通过加热或紫外光（UV光）照射、或者两种兼有的方式实现辐射固化剂的固化，使CF基板与TFT基板黏合在一起。现今主流的固化方法是采用加热与UV光照射两种方式相结合共同实现固化。当用UV光照射辐射固化剂使之固化时，UV光一般从TFT基板一侧进行照射。在固化制程中，UV光与TFT基板之间会放置UV光罩（UV mask）用以遮挡UV光照射到显示区域，防止UV光对显示区域内的聚酰亚胺（PI）材料与液晶材料造成损伤。
以上方法存在以下缺陷：每当改变面板尺寸时，就要制作相应的UV光罩，造成资源浪费的问题，增加了制造成本。同时，由于TFT基板***通常会有大面积的不透光金属走线，固化制程中金属走线下方的辐射固化剂会由于金属走线的遮光而造成固化的不足。

【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
图1是本发明实施例的液晶显示面板的制造方法的流程图。图2是由图1所示的制造方法制造的液晶显示面板的一实施例的结构示意图。如图1和2所示，本实施例的液晶显示面板的制造方法包括如下步骤：
步骤S100：相对设置第一基板21和第二基板22。
在本实施例中，第一基板21包括彩色滤光片阵列区211以及设置于彩色滤光片阵列区211***的第一非显示区212，第二基板22包括与彩色滤光片阵列区211相对的薄膜晶体管阵列区221以及位于薄膜晶体管阵列区221***的第二非显示区222，第二非显示区222上形成有第一黑矩阵2221。薄膜晶体管阵列区221是指由薄膜晶体管（即TFT，未图示）以及像素电极（未图示）所构成的阵列区。第一黑矩阵2221包围薄膜晶体管阵列区221，用于阻挡其边缘区域因固化辐射的衍射而导致的不良。
在本实施例中，彩色滤过片阵列区211包括以阵列方式排列的多个彩色滤光片单元2111以及位于彩色滤光片单元2111之间的第二黑矩阵2112。其中，多个彩色滤光片单元2111用于透射预定波段的光线，同时反射或吸收其他波段的光线，以实现液晶显示面板的彩色显示。多个彩色滤光片单元2111一般按照不同基色交替排列，比如：红色、绿色、蓝色等。第二黑矩阵2112的主要作用是用于防止彩色滤光片单元2111之间的漏光，以增强液晶显示面板色彩反差的对比。
在本实施例中，在第一非显示区212的与第一黑矩阵2221对应的区域涂布辐射固化剂23。在其他实施例中，辐射固化剂23也可以涂布于第一黑矩阵2221上，或者是涂布于第一基板21或第二基板22上的与第一非显示区212对应的任意适当位置。
步骤S200：利用固化辐射从第一基板21的远离第二基板22的一侧照射第一基板21，以使入射到彩色滤光片阵列区211的固化辐射被彩色滤光片阵列区211吸收，入射到第一非显示区212的固化辐射对辐射固化剂23进行固化，进而黏合第一基板21和第二基板22。
在本实施例中，辐射固化剂23优选为紫外固化剂，而固化辐射优选为紫外光。当紫外光从第一基板21的一侧照射时，第一基板21的彩色滤光片阵列区211的彩色滤光片单元2111以及第二黑矩阵2112会吸收约95%的紫外光，而彩色滤光片阵列区211***的第一非显示区212不能吸收紫外光。紫外光入射到第一非显示区212上的辐射固化剂23后，辐射固化剂23中的光引发剂吸收紫外光的光能量而分解成游离基进而引发单体进行光聚合反应，进而黏合第一基板21和第二基板22。其中，在进行固化时，优选加热与固化辐射两种方式共同进行。
图3是由图1所示的制造方法制造的液晶显示面板的另一实施例的结构示意图。如图3所示，本实施例的液晶显示面板包括相对设置的第一基板31和第二基板32。
在本实施例中，第一基板31包括彩色滤光片阵列区311以及设置于彩色滤光片阵列区311***的第一非显示区312，第二基板32包括与彩色滤光片阵列区311相对的薄膜晶体管阵列区321以及位于薄膜晶体管阵列区321***的第二非显示区322，第二非显示区322上形成有第一黑矩阵3221，薄膜晶体管阵列区321上形成有第二黑矩阵3211。彩色滤过片阵列区311包括以阵列方式排列的多个彩色滤光片单元3111。第二黑矩阵3211的位置与彩色滤光片单元3111之间的分界位置对应。
在本实施例中，在第一非显示区312的与第一黑矩阵3221对应的区域涂布辐射固化剂33。在其他实施例中，辐射固化剂33也可以涂布于第一黑矩阵3221上，或者是涂布于第一基板31或第二基板32上的与第一非显示区312对应的任意适当位置。
本实施例与图2所示的实施例的区别在于，第一黑矩阵3221和第二黑矩阵3211均形成于第二基板32上，进而可同步形成，减少了在第一基板31上形成第二黑矩阵3211的步骤，简化了制程。当利用固化辐射从第一基板31的远离第二基板32的一侧照射第一基板31，第一基板31的彩色滤光片阵列区311的彩色滤光片单元3111吸收大部分固化辐射，而彩色滤光片阵列区311***的第一非显示区312不能吸收固化辐射，进而对辐射固化剂33进行固化。此时，虽然彩色滤光片单元3111之间会透射少量的固化辐射，但透射的固化辐射所造成的不良被第二基板32上的第二黑矩阵3211遮挡，进而不会影响显示效果。
本发明进一步提供了由上述制造方法制造的如图1和图2所示的液晶显示面板，该液晶显示面板的具体结构已经在上文进行详细描述，在此不再赘述。
通过上述方式，本发明的液晶显示面板的制造方法采取固化辐射从彩色滤光片阵列区所在基板一侧进行照射，利用彩色滤光片阵列区对入射到其上的固化辐射进行吸收，并利用彩色滤光片阵列区***的非显示区对入射到其上的固化辐射进行透射，进而实现辐射固化剂的固化，有效的解决了因薄膜晶体管阵列区的***金属走线的遮挡而产生的辐射固化剂固化不足的问题，并且不需要UV光罩，从而降低了液晶显示面板的制造成本。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
