Description

液晶显示装置及其液晶显示面板
【技术领域】
本发明涉及显示技术领域，具体涉及一种液晶显示装置及其液晶显示面板，特别涉及液晶显示面板的非显示区域的密封结构。
【背景技术】
液晶显示面板普遍设置有框胶（Sealant），所述框胶设置于其边缘以对液晶显示面板进行密封，从而防止液晶分子泄露，并且为了提高显示效果，框胶一般被设计的很窄，以适应窄边框的趋势。此外，框胶中设置有用以支撑上下基板的液晶盒间隙（Cell Gap）并实现上下基板导通的间隔件（Spacer）和金球（Au Ball）。间隔件主要由密胺树脂、聚苯乙烯树脂等材料制成，这些材料比显示区（Active Area，AA）中的支撑物（Photo Spacer，PS）的压缩率要大，框胶所受压缩的情况比较严重，这使得框胶所在区域中的液晶盒间隙小于显示区中的液晶盒间隙，从而使得框胶所在区域出现间隙光斑（Gap Mura）的现象。
【发明内容】
鉴于此，本发明实施例提供一种液晶显示装置及其液晶显示面板，可在确保窄边框效果的前提下避免框胶所在区域出现间隙光斑现象。

【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，本发明以下所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
图1是本发明的液晶显示面板一实施例的结构俯视图，图2是图1所示的液晶显示面板的结构剖视图。结合图1和图2所示，液晶显示面板10包括相对间隔设置的阵列基板（Thin Film Transistor，TFT基板或薄膜晶体管阵列基板）11和彩膜基板12（Color Filter，CF基板或彩色滤光片基板）、填充于阵列基板11和彩膜基板12之间的液晶13、包围液晶13的密封框件14。所述密封框件14夹设于阵列基板11和彩膜基板12之间且设置为矩形，并且密封框件14用于对由阵列基板11和彩膜基板12组成的液晶盒进行密封，或者说，所述密封框件14利用自身的胶黏性对盒连接阵列基板11和彩膜基板12。
液晶显示面板10包括显示区和非显示区，非显示区设置于显示区的外侧且包围显示区，密封框件14位于非显示区内。
图3是图1所示的液晶显示面板沿A-A方向一实施例的剖视图。如图3所示，所述密封框件14包括框胶141以及多个第一支撑物142（并不限于图中示例性的三个），多个第一支撑物142内嵌形成于框胶141中，且每一第一支撑物142均开设有接触孔143，使得阵列基板11和彩膜基板12之间通过接触孔143实现导通。
例如，接触孔143沿垂直于阵列基板11的方向上贯穿设置于阵列基板11上且临近液晶13的平坦层L，接触孔143的侧壁上可以覆盖有导电介质层144，彩膜基板12上的公共电极121和阵列基板11上的公共线111通过导电介质层144即可实现电连接。
所述第一支撑物142与位于液晶显示面板10的显示区内的第二支撑物的材料相同，第二支撑物即为控制阵列基板11和彩膜基板12之间间隙厚度及均匀性的PS，即，本发明实施例的液晶显示面板10的显示区和非显示区都采用PS作支撑物，两者保持相同的压缩率，使得显示区和非显示区的液晶盒间隙保持一致，从而避免框胶141所在区域出现间隙光斑现象，并确保液晶显示面板10的窄边框效果。
此外，阵列基板11和彩膜基板12之间通过第一支撑物142开设的接触孔143即可实现导通，无需现有技术中普遍采用的间隔件和金球，相比之下，节省了间隔件和金球的材料成本，并且避免了间隔件和金球的设置工序，从而大大降低了生产制造成本。
鉴于第一支撑物142与第二支撑物的材料相同，为进一步减少液晶显示面板10制造工序，本发明实施例可同步形成第一支撑物142与第二支撑物，即二者采用同一道PS光罩刻蚀得到。
图4是图1所示的液晶显示面板沿A-A方向另一实施例的剖视图。如图4所示，密封框件14还包括包围液晶13的第一挡墙144和第二挡墙145，框胶141以及第一支撑物142夹持于第一挡墙144和第二挡墙145之间，不仅可以避免框胶141因外压朝向或背向液晶13外溢，还能够作为阵列基板11和彩膜基板12之间的支撑物。
参照该原理，本发明其他实施例可设置密封框件14包括框胶141和多个色阻块，此时设置框胶141包括多个间隔设置的框胶分段，色阻块与框胶分段并列设置，密封框件14同样可实现密封及支撑作用。
上述第一挡墙144和第二挡墙145与阵列基板11上的任意结构同步形成，所述结构包括栅极绝缘层、钝化层、黑矩阵层以及像素电极层（上述公共线111），或者，与彩膜基板12上的任意结构同步形成，所述结构包括彩膜基板12上的公共电极121、黑矩阵层（此时阵列基板11上可未设置黑矩阵层）。在本发明的其他实施例中，密封框件14还可以仅包括第一挡墙144和第二挡墙145中的一个。
图5是图1所示的液晶显示面板沿A-A方向又一实施例的剖视图。如图5所示，在图3所示实施例的描述基础上但与之不同的是，本实施例的密封框件14进一步包括形成于阵列基板11上的第一色阻层146，第一支撑物142设置于第一色阻层146上，具体设置于平坦层L上，并且接触孔143在垂直于阵列基板11的方向上贯穿平坦层L和第一色阻层146。
对于图3和图4所示实施例，如果仅采用第一支撑物142作支撑物，那么对于阵列基板11和彩膜基板12之间具有较大间隙的液晶显示面板10，则需要额外的增加制造工序，例如在第一支撑物142上继续采用相同材料分段涂布及光罩刻蚀形成支撑物。然而，本实施例可在液晶显示面板10的色阻制程中同步形成（具有一定厚度的）第一色阻层146和第二色阻层，其中第二色阻层为液晶显示面板10的显示区内的像素电极的色阻，而后在第一色阻层146上形成第一支撑物142即可，本实施例可适用于较高支撑物需求的液晶显示面板10。
在本发明实施例中，多个第一支撑物142可以为圆柱状结构、梯形柱状结构、锥体结构等的任意组合，并不予以限制。
本发明还提供一种实施例的液晶显示装置，其包括上述任一实施例的液晶显示面板10，因此具有与其相同的有益效果。
本发明实施例的目的是，采用与位于显示区内的支撑物相同的材料制造内嵌于框胶中的支撑物，使得显示区和非显示区都采用PS作支撑物，可以保持相同的压缩率，从而使得显示区和非显示区的液晶盒间隙保持一致，避免框胶所在区域出现现有技术中的间隙光斑现象，此外液晶显示面板的两基板之间通过PS开设的接触孔即可导通，无需采用现有技术的间隔件和金球，可降低制造成本。
在此基础上，前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，例如各实施例之间技术特征的相互结合，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。
