近年来,已经开发了各种液晶面板,在液晶面板中,液晶被包括在两个基板之间,并且两个基板上分别形成有配向层(PI),以使液晶分子具有初始取向。液晶分子在电场的作用下改变其取向,从而改变液晶面板的透光率和/或改变穿过液晶面板的光的传播方向。因此,液晶面板可以用于形成液晶显示面板、液晶透镜面板等。
为了保持液晶面板的两个基板之间的距离以形成用于填充液晶的空间,在液晶面板的两个基板之间通常形成有隔垫物(photo spacer,简称为PS)。PS通常是具有弹性的聚合物,例如,在液晶显示面板中,PS的底部可以形成在彩膜(CF)基板侧的黑矩阵(BM)所在的区域,PS的上部可以顶在阵列基板侧的薄膜晶体管(TFT)上。

图1是示出根据本公开一个实施例的形成有第一隔垫物的第一基板的示意图,图2是根据本公开一个实施例的形成有第二隔垫物的第二基板的示意图,图3是根据本公开一个实施例的将第一基板和第二基板对合后第一隔垫物和第二隔垫物的示意图。参照图1至图3,根据本公开一个实施例的液晶面板可以包括:第一基板100、与第一基板100相对的第二基板200、形成在第一基板100和第二基板200之间的液晶层(未示出);第一隔垫物110,形成在第一基板100上,沿第一方向延伸;第二隔垫物210,形成在第二基板200上,与第一隔垫物110相对且沿第二方向延伸。
在本实施例中,如图1和图2所示,第一基板100可以是形成 有栅极线120和数据线130的阵列基板,第二基板200可以是形成有黑矩阵220和滤色器230的彩膜基板,然而本公开不限于此,第一基板100和第二基板200可以是用于形成液晶面板的其它基板。
在本实施例中,第一方向和第二方向可以彼此垂直,并且第一方向可以是附图中示出的列方向,第二方向可以是附图中示出的行方向。然而本公开不限于此,根据液晶面板的具体布置方式,第一方向和第二方向之间可以具有除90度之外的其它夹角,并且第一方向和第二方向也不限于行方向和列方向。例如,当液晶面板具有沿诸如对角线方向的其它方向的布线结构和/或遮光结构时,可以沿这些方向布置第一隔垫物110和第二隔垫物210。
根据本实施例,第一隔垫物110和第二隔垫物210彼此接触但不连接。具体地说,当第一基板100和第二基板200彼此对合以形成液晶盒结构时,第一隔垫物110和第二隔垫物210彼此接触,从而支撑第一基板100和第二基板200,以使第一基板100和第二基板200之间保持预定的距离。
例如,如图1所示,第一基板100上包括多条彼此交叉的数据线130和栅极线120。数据线线130沿竖直方向(列方向)延伸,栅极线120沿水平方向(行方向)延伸。图1中示出了第一隔垫物110形成在数据线130上。如图1所示,为了示出的方便,最右侧的两条数据线130上没有形成第一隔垫物110,然而本实施例不限于此,最右侧的两条数据线130上也可以形成有第一隔垫物110。
另外,如图2所示,第二基板200包括对应于数据线130和栅极线120的黑矩阵220。在液晶面板中,黑矩阵220可以阻挡光线,从而避免用户看到液晶面板中的布线和其它电路结构,有利于提高对比度。第二隔垫物210形成在黑矩阵220的对应于栅极线的部分上。
在本实施例中,“A形成在B上”的描述可以表示A直接形成在B上,或者也可以在A和B之间形成一个或多个中间结构。例如,第一隔垫物110形成在数据线130上可以表示第一隔垫物110直接形成在数据线130上,也可以表示第一隔垫物110形成在数据线130上方,并且在第一隔垫物110和数据线130之间形成有一个或多个中 间结构。
参见图1和图2,第一隔垫物110被形成为连续的直线,第二隔垫物210被形成为间断的直线,然而本公开不限于此,第一隔垫物110和第二隔垫物210可以被形成为具有连续直线和/或间断的直线中的任何一种形式。另外,第一隔垫物110和第二隔垫物210的具体形状不限于直线,根据实际需要,第一隔垫物110和第二隔垫物210可以具有其它形状。
在一个实施例中,第一隔垫物110和第二隔垫物210分别与第一基板100和第二基板200接触的部分可以具有平坦的表面。在这种情况下,第一隔垫物110和第二隔垫物210可以分别与第一基板100和第二基板200紧密接触,从而有利于稳固地将第一隔垫物110和第二隔垫物210形成在第一基板100和第二基板200上。另外,由于第一隔垫物110和第二隔垫物210的平坦表面,在受到按压力而滑动的过程中,能够避免液晶盒厚发生变化,从而避免产生水波纹等缺陷。
第一隔垫物110可以具有包括多个第一隔垫物,所述多个第一隔垫物具有相同的高度。例如,对应于多条数据线130,可以形成多个第一隔垫物110,并且这些第一隔垫物110具有相同的高度。
另一方面,第二隔垫物210可以包括多个第二主隔垫物和多个第二辅隔垫物(未示出),其中,第二辅隔垫物的高度可以小于第二主隔垫物。在这种情况下,由于第一隔垫物110具有相同的高度,而第二隔垫物210包括具有不同高度的多个第二主隔垫物和多个第二辅隔垫物,因此通过使第一隔垫物110和第二隔垫物210彼此接触而获得的隔垫物整体具有不同的高度。因此,能够确保液晶盒内的液晶具有一定的上下波动范围,从而有利于避免产生Mura等缺陷。
第一隔垫物110和第二隔垫物210之间接触的部分彼此不连接,即,第一隔垫物110和第二隔垫物210彼此未被形成为整体,因此它们之间可以相对于彼此移动。更具体地说,第一隔垫物110和第二隔垫物210接触的部分可以沿第一隔垫物110和/或第二隔垫物210的延伸方向滑动。
在这种情况下,当液晶面板受到外力冲击时,第一隔垫物110 和第二隔垫物210彼此接触的部分之间产生滑动。例如如图4所示,其示出了根据本公开一个实施例的液晶面板受力导致第一隔垫物和第二隔垫物相对滑动的状态的示意图,第二隔垫物210和第一隔垫物110之间彼此沿第一方向和第二方向相对滑动,使得第二隔垫物210进入到了如图所示的对应于红色滤色器的区域(对应于红色子像素的区域,即,形成有配向层的区域)中,然而由于第二隔垫物210形成在第二基板200上,因此其相对于第二基板200彼此不会相对移动。另一方面,第二隔垫物210的自由端与第一隔垫物110彼此接触,因此由于被第一隔垫物110垫高,第二隔垫物210不会与第一基板100接触,因此即使第二隔垫物210滑动至对应于红色滤色器的区域(对应于红色子像素的区域,即,形成有配向层的区域)中,第二隔垫物210的自由端也不会与第一基板100和/或第二基板200接触而划伤第一基板100和/或第二基板200。
因此,本实施例的液晶面板能够防止隔垫物的移动导致基板上的配向层的划伤。另外,如上文解释的,即使隔垫物移动至形成有配向层的区域,也不会导致配向层的损坏,因此不需要将黑矩阵的区域形成得太大,从而有利于提高液晶面板的开口率。
根据本实施例,液晶面板包括:第一基板、与第一基板相对的第二基板、形成在第一基板和第二基板之间的液晶层;第一隔垫物,形成在第一基板上,沿第一方向延伸;第二隔垫物,形成在第二基板上,与第一隔垫物相对且沿第二方向延伸。根据本公开的液晶面板,能够防止隔垫物的移动导致基板上的配向层的划伤,并且有利于提高开口率和防止水波纹的产生。
图5是根据本公开一个实施例的液晶面板的制备方法的流程图。参照图5,根据本公开实施例的制备液晶面板的方法可以包括:步骤S110,在第一基板上形成沿第一方向延伸的第一隔垫物;步骤S120,在第二基板上形成沿第二方向延伸的第二隔垫物;步骤S130,将第一基板与第二基板对合,其中,所述第一隔垫物和所述第二隔垫物彼此相对,使得所述第一基板和所述第二基板之间保持一定距离;以及步骤S140在所述第一基板和所述第二基板之间填充液晶材料。
根据一个实施例,在步骤S130中,使第一隔垫物与第二隔垫物彼此相对的过程中,可以使第一隔垫物与第二隔垫物彼此接触但不连接。关于上述方法的其它具体细节,可以参考前述实施例中对于液晶面板的描述,因此在这里将不再赘述。
根据本实施例,制备液晶面板的方法包括:在第一基板上形成沿第一方向延伸的第一隔垫物;在第二基板上形成沿第二方向延伸的第二隔垫物;将第一基板与第二基板对合,其中,所述第一隔垫物和所述第二隔垫物彼此相对,使得所述第一基板和所述第二基板之间保持一定距离;以及在所述第一基板和所述第二基板之间填充液晶材料。根据本公开的方法制备的液晶面板,能够防止隔垫物的移动导致基板上的配向层的划伤,并且有利于提高开口率和防止水波纹的产生。
