Description
本发明涉及作为制造液晶单元时的中间体的液晶用单元集合体及使用这种单元集合体的液晶单元副集合体的制造方法。
英国专利GB2039679A公开了一种液晶单元集合体,具有上下两块玻璃板,用密封带形成具有多个液晶注入用空间的单元集合体,每单元设有液晶注入口,各注入口在集合体中是互通的。
通过蒸镀等形成薄膜的手段,使液晶存在于形成电极的二片玻璃板之间,由于通过电极向这样进行定向的液晶分子上施加电压,所以,使定向状态根据电极状态的不同而发生变化,从而部分地遮蔽光的透射的液晶显示装置被广泛使用。
现将构成上述液晶显示装置的主要部分的液晶单元的现有制造方法,结合图6予以说明如下。
首先,如图6(a)所示那样,预先准备好液晶用单元集合体100。该液晶用单元集合体100在将2片玻璃板101贴合的同时,在2片玻璃板101之间,用密封剂102,在横向及纵向分别形成多个液晶注入用空间103。在液晶注入用空间103里,形成液晶注入口104,另外,在玻璃板101上预先形成电极105及端子106。
接着,将上述液晶用单元集合体100,如图6(b)所示的那样,沿横向切断后,则成为多个液晶注入用空间103互相连接的液晶用单元副集合体100a。该液晶用单元副集合体100a的一侧,开有液晶注入口104。
然后,在将上述液晶用单元副集合体100a的液晶注入用空间103内减了压的状态下,将液晶注入口104部分浸渍在液晶内,如图6(c)所示的那样,向液晶注入用空问103内填充液晶107,然后,再如图6(d)所示的那样,在密封了液晶注入口104部分以后,再如图6(e)所示的那样,切断成各个单元100b,再如图6(f1)和6(f2)所示的那样,在各个单元100b的表面贴附偏振光板108,这样,液晶单元110便制作完成。其中,图6(f1)为液晶单元的正视图,图6(f2)为侧视图。
在上述现有技术液晶单元的制作方法中,不能一次将液晶注入到液晶用单元集合体100的全体内,因此,由于是沿横向将液晶用单元集合体100切断而成的一侧开有液晶注入口104的,液晶用单元副集合体100a,然后再注入液晶,从而其注入效率低。
此外,因为将液晶用单元集合体较早地切断成小段,所以给偏振光板的贴附等后续工序带来麻烦。
而且,当注入液晶时,由于注入用空间103的外侧部分,具体地说,是在形成端于106的部分,侵入了液晶,所以必须进行清洗去除该液晶的工作。
本发明的目的是提供一种液晶用单元集合体及液晶单元副集合体的制造方法,以解决上述现有技术的问题。
为了解决上述问题,有关本申请的第一发明的一种液晶用单元集合体,它是在所贴合的二片玻璃基板之间,用密封剂,在纵向及横向形成多个液晶注入用空间的液,其特征在于:上述在纵向所形成的多个液晶注入用空间,通过液晶注入口互相连通,在横向上,相邻的液晶注入空间互不连通。
此外,有关本申请的第二发明的液晶单元副集体的制造方法,所述液晶单元副集合体的制备方法,在室内将装满液晶的容器和权利要求1所述的液晶用单元集合体进行固定,接着将室内抽真空、减压,其特征在于:然后将液晶用单元集合体的下端浸渍在容器内的液晶中,在这种状态下,解除室内的减压状态,从而将液晶填充到上述液晶用单元集合体的液晶注入用空间内,然后在液晶用单元集合体的各单元的表面贴附偏振光板,在切断贴附该偏振光板的液晶用单元集合体的同时,密封各单元的液晶注入口。
将液晶用单元集合体的下端浸渍到容器内的液晶中,在这种状态下,如果解除室内的减压状态,则液晶注入用空间内便成为真空状态,因为外部是大气压,所以液晶便从最下端的液晶注入口被吸入到液晶注入用空间内。

实施例:
以下,根据附图详细说明本发明。
图1是有关本发明的液晶用单元集合体的整体图,液晶用单元集合体1是由二片玻璃基板2,2贴合而成的,在二片玻璃基板2,2间,用密封剂3在横向及纵向分别形成多个液晶注入用空间4。在各液晶注入用空间4内,形成液晶注入口5,纵向的液晶注入用空间4,通过液晶注入口5互相连通。
在多个液晶注入用空间4内最上段所形成的液晶注入用空间4的上方,形成液晶积存部6。该液晶积存部6的形状不限于与如图示那样的液晶注入用空间4同宽的扁平形状,而且,也可以是圆形、突起状等任意形状。
另外,在2片玻璃基板2,2间,用密封剂3,形成液晶注入用空间4的同时,也划分成液晶注入用空间4的外侧空间7。该外侧空间7和注入用空间4互不连通。
在玻璃基板2上预先形成电极8及端子9。这些电极8及端子9,采用喷镀,化学气相淀积、丝网印刷等方法来形成,材料使用ITO(铟、锡诺莫合金、氧化物)等。电极8在液晶注入用空间4部分上形成,使端子9在与其相邻部分外侧空间7内形成。另外,图中所示例子中表示出了仅在一个单元里的电极8和端子9,但是实际上同样的电极8和端子9形成于各个单元里。
根据图4及图5来说明用上述液晶用单元集合体制造液晶单元1的工艺流程。
首先,在图4(a)所示的空的液晶用单元集合体1的液晶注入用空间4内,按图4(b)所示的那样填充液晶10。
为要填充液晶10,按图5所示的那样,在室11内固定液晶用单元集合体1和装满了液晶的容器12,接着将室11内抽真空减压,然后,将液晶用单元集合体1的下端浸渍到容器12内的液晶10中,再在这种状态下,解除室11内的减压状态。这样一来,液晶注入用空间4内成为真空状态,因为外部是火气压,所以液晶10从最下端的液晶注入口5被吸入到液晶注入用空间4内。
在上述液晶10的填充工序中,因为纵向的液晶注入用空间4用液晶注入口5来连通,所以通过一次注入,液晶10便能按顺序从下端至上端的液晶注入用空间4吸入。
因为在最上部的液晶注入用空间4的上方设有液晶积存部6,所以在液晶注入用空间4内,所存有的若干空气,在注入时,空气集中在该液晶积存部6内,从而,在液晶注入用空间4内,液晶10能迅速地填充。
另外,在以上的注入过程中,由于外侧空间7与液晶注入用的空间4是互相划分开的,所以液晶不能侵入到外侧空间7里。
如上所述的那样,如果液晶注入用空间4内填充液晶10后,从室11取出液晶用单元集合体制1,如图4(c1)和4(c2)所示,在液晶用单元集合体1的各单元的表面上贴附偏振光板13,接着如图4(d1)和4(d2)所示,沿横向切断贴附了偏振光板13的液晶用单元集合体1,作为液晶用单元副集合体1a,如图4(e)所示,用玻璃14密封切断的液晶用单元副集合体1a两侧面的液晶注入口,最后,如图4(f)所示,切断成各液晶单元15。
如以上所说明的那样,在所贴合的2片玻璃基板之间,用密封剂,沿横向及纵向形成多个液晶注入用空间的液晶用单元集合体中,由于通过液晶注入口,将上述沿纵向形成的多个液晶用空间相互连通,所以与现有技术那样沿横向切断液晶用单元集合体后,再注入液晶的方法相比,由于可以一次注入从而使制作效率大幅度提高。
此外,在沿纵向所形成的多个液晶注入用空间里最上部的液晶注入用空间的上方如果形成液晶积存部,则由于注入时可以在液晶积存部里聚集,在减压时未抽吸完的空气,所以能够缩短注入时间。更具体地说,在没有设液晶积存部的情况下,需要花费6小时,而在设有液晶积存部的情况下,只需1小时就能够注完。
另外,相对于液晶注入用空间,在用密封剂所划分的端子形成用的外侧部分里,由于液晶侵入,所以可以省略洗净液晶的后续工序,从而,可使制造工序简单,成本下降。
此外,与最终工序接近的工序,例如,直到进行贴合偏振光板的工序时为止,由于不需要将液晶用单元集合体切断成小段,所以产品的管理及操作程序便利,可减少工序数。
