Description

一种显示基板及其制造方法、液晶显示装置
技术领域
本发明涉及显示技术领域，特别涉及一种显示基板及其制造方法、液晶显示装置。
背景技术
薄膜晶体管液晶显示器(英文：Thin Film Transistor-Liquid CrystalDisplay，简称：TFT)LCD)技术经过最近几十年的发展，技术和工艺日趋成熟。已经取代冷阴二极管(英文：Cold Cathode Fluorescent Lamp，简称：CCFL)显示器，成为显示领域的主流产品。
随着TFT)LCD产业的发展，液晶显示产品的竞争日趋激烈，一般地，在移动显示产品中，将显示区域到显示屏边缘定义为边框。边框的存在会降低整个显示屏的视觉效果，尤其边框区域越大，视觉效果越差。因此窄边框甚至无边框视觉效果成为高品质显示屏的主流趋势。
但是，随着TFT)LCD面板尺寸越来越小，在液晶滴注工艺中，液晶在滴下之后，封框胶紫外固化之前，液晶分子就可能与未固化的封框胶产生接触，从而发生液晶与封框胶的互相污染以及液晶穿刺封框胶现象。特别是对于窄边框产品，相邻的两个待切割基板的封框胶之间甚至没有距离，容易造成封框胶的流动，导致封框胶的分布不均匀，从而影响面板的切割，进一步导致显示面板产生分断不良，甚至产生液晶泄漏等不良。
发明内容
为了克服由于封框胶流动而导致的面板切割分断不良等问题，本发明实施例提供了一种显示基板及其制造方法、液晶显示装置。所述技术方案如下：
本发明实施例的一方面，提供了一种显示基板，包括：呈阵列形式排列的至少一个待切割基板区域；
在所述显示基板的表面，沿所述待切割基板区域四周涂布有封框胶，相邻待切割基板区域之间设置有用于阻挡封框胶的挡墙。
本发明实施例的另一方面，提供了一种显示基板制造方法，包括：
在显示基板表面形成挡墙，所述显示基板包括呈阵列形式排列的至少一个待切割基板区域，所述挡墙位于相邻待切割基板区域之间；
在所述待切割基板区域四周涂布封框胶。
本发明实施例的又一方面，提供了一种液晶显示装置，所述液晶显示装置包括对盒成型的一对显示基板，至少一个显示基板为如上所述的显示基板。
本发明实施例提供的显示基板及其制造方法、液晶显示装置，显示基板包括呈阵列形式排列的至少一个待切割基板区域；在显示基板的表面，沿待切割基板区域四周涂布有封框胶，相邻待切割基板区域之间设置有用于阻挡封框胶的挡墙。采用这样一种挡墙结构，通过在与两个相邻的待切割基板区域中间的切割线上制作用于限制未固化的封框胶流动的挡墙，从而可以有效达到限制封框胶流动的目的，有效避免了由于封框胶流动而导致的封框胶分布不均匀，从而保证了胶宽，显著克服了显示面板产生分断不良，甚至产生液晶泄漏等不良的问题。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
本发明实施例提供的显示基板1，如图1所示，包括：呈阵列形式排列的至少一个待切割基板区域2。
在显示基板1的表面，沿待切割基板2区域四周涂布有封框胶3，相邻待切割基板2区域之间设置有用于阻挡封框胶的挡墙4。
本发明实施例提供的显示基板，包括呈阵列形式排列的至少一个待切割基板区域；在显示基板的表面，沿待切割基板区域四周涂布有封框胶，相邻待切割基板区域之间设置有用于阻挡封框胶的挡墙。采用这样一种挡墙结构，通过在与两个相邻的待切割基板区域中间的切割线上制作用于限制未固化的封框胶流动的挡墙，从而可以有效达到限制封框胶流动的目的，有效避免了由于封框胶流动而导致的封框胶分布不均匀，从而保证了胶宽，显著克服了显示面板产生分断不良，甚至产生液晶泄漏等不良的问题。
具体的，如图2所示，在本发明实施例中，显示基板1可以为彩膜基板，该彩膜基板包括彩色滤光结构5。
挡墙4与彩色滤光结构5的材料可以相同，且挡墙4与彩色滤光结构5同层形成。

优选的，在本发明实施例中，挡墙4的长度可以大于等于待切割基板2的长度，挡墙4的宽度大于0.3μm(微米)小于0.5μm。
采用这样一种挡墙结构，通过在与两个相邻的待切割基板区域中间的切割线上制作用于限制未固化的封框胶流动的挡墙，从而可以有效达到限制封框胶流动的目的，有效避免了由于封框胶流动而导致的封框胶分布不均匀，从而保证了胶宽，显著克服了显示面板产生分断不良，甚至产生液晶泄漏等不良的问题。
本发明实施例提供的显示基板制造方法，如图4所示，包括：
步骤401、在显示基板表面形成挡墙，显示基板包括呈阵列形式排列的至少一个待切割基板区域，挡墙位于相邻待切割基板区域之间。

具体的，如图5所示，所述在显示基板表面形成挡墙的步骤具体可以包括：
步骤501、在透明基板的表面形成彩膜层。
步骤502、在彩膜层的表面通过一次构图工艺分别形成位于每一待切割基板区域内的彩色滤光结构以及挡墙，挡墙位于相邻待切割基板区域之间。

或者，还可以如图6所示，所述在显示基板表面形成挡墙的步骤具体可以包括：
步骤601、在显示基板表面形成隔垫物材料层。
步骤602、在隔垫物材料层的表面通过一次构图工艺分别形成隔垫物以及挡墙，挡墙位于相邻待切割基板区域之间。
这样一来，通过将挡墙与隔垫物同时制作，从而可以无需额外增加工序即可实现挡墙的制作，大大降低了该结构显示基板的生产成本。
优选的，在本发明实施例中，挡墙的长度可以大于等于待切割基板的长度，挡墙的宽度大于0.3μm小于0.5μm。
