Description

形成间隔物的方法及液晶面板
技术领域
本发明涉及液晶面板的生产领域, 具体涉及一种在液晶面板中形成间隔物的方法及 由此得到的液晶面板。 背景技术
液晶显示器以其高显示品质、价格低廉、携带方便等优点, 是目前使用最广泛的一种 平板显示器,其已经逐渐成为各种电子设备如移动电话、个人数字助理 (PDA)、数字相机、 †算机屏幕或笔记本电脑屏幕所广泛应 ffl具有高分辨率彩色屏幕的显示器。
目前普遍采 ]¾的液晶显示器,通常有上下衬底和中间液晶层组成,衬底有玻璃和电极 等组成。 另外, 传统的液晶显示面板是由一彩色滤光基板 (color filter), —薄膜晶体管矩阵 基板 (thin film transistor array substrate, TFT array substrate) 以及 ""配置于此两基板间的液 晶 (liquid crystal ί aver) 所;'沟成。
近年来, 更提出了将彩色滤光层直接整合于薄膜晶体管矩阵基板上 (Coioir Filter on Array, COA) 或是将黑色矩阵层制作于薄膜晶体管矩阵基板上 (Black matrix on Array, BOA) 的技术或是 FFS技术 (fringe field switching,边缘电场切换),如将 COA 基板或 BOA 基板与另一不具备彩色滤光层或黑矩阵层的对向基板组立, 并于两基板间填入液晶分子, 以形成液晶显示面板。 于彩色滤光层是仅直接形成于薄膜晶体管阵列基板上, 因此不会 产生对位误差。 而 此种液晶显示面板可具有较佳的分辨率且其像素的开口率亦较高。
通常,在液晶面板中两个基板之间会设置间隔物。间隔物的主要功能是维持液晶显示 器上 Τ两片基板的距离, 以形成一定的空间用于填充液晶。 目前, 所述的间隔物主要以散 布的方式填充在所述两片基板之间, 然而, 如果间隔物分布不好的话, 会影响显示器的对 比度、分辨率以及可视角度, 尤其是随着液晶面板的大型化, 间隔物的均一分布变得越来 越重要。
传统的间隔物的设†方法有两种, 一种是使用单一间隔物(如图 i所示) , 另外一种 是使用混合间隔物 (图 2所示) , 即使用弱曝的方式形成副间隔物。
第一种方法是所有的 PS都具有相同的高度, 这种 PS的优点是 Taper angle大, 所需 的黑色矩阵宽度窄, 具有高的开口率和穿透率, 缺点是只有一种高度的间隔物, 液晶范围 小。
第二种方法是设计具有不同的高度的混合间隔物 于具有了较高高度的主间隔物和 较低高度的副间隔物, 此种设计的液晶范围变大(如图 2所示) , 但是这种方法也有其缺 点, 形成的副间隔物的锥形角度小且宽度大, 所需黑色矩阵的遮覆宽度大, 影响幵口率和 穿透率或者成本较高, 不利于降低生产成本。 发明内容
本发明的目的在于提供一种在液晶面板内形成间隔物的方法,已解决现有技术中存在 的 题。
为了实现上述目的, 本发明提供了以下技术方案-

ii) 在另一个对向基板上形成主间隔物和副间隔物, 其中, 副间隔物的高度高于主间 隔物的高度- iii) 将薄膜晶体管阵列基板与对向基板组合, 对向基板的主间隔物抵住薄膜晶体管阵 列基板, 副间隔物延伸入所述凹槽内。
2)在本发明的第 ί )项的一个优选实施方式中,所述曝光的曝光能量为; 20〜80mj/cm2
3 )在本发明的第 1 )或第 2 )项的一个优选实施方式中, 所述薄膜晶体管的基板侧上 的材料层为彩膜层或有机保护层。
4) 在本发明的第 1 ) -第 3 ) 项中任一项的一个优选实施方式中, 所述形成了凹槽的 材料上还设置有一层 ΓΤΟ像素电极。
5 ) 在本发明的第 1 ) -第 4) 项中任一项的一个优选实施方式中, 所述主间隔物的高 度为 1- 5μηι。
6) 在本发明的第 1 ) 项-第 5 ) 项中任一项的一个优选实施方式中, 所述副间隔物的 高度为 1 5μηι。
7) 在本发明的第 1 ) 项-第 6) 项中任一项的一个优选实施方式中, 所述副间隔物比 主间隔物高 0.1〜1 μΐϋ。
8) 在本发明的第 1 ) 项-第 7) 项中任一项的一个优选实施方式中, 所述步骤 i)中的 曝光利用的掩膜的图案为条纹状、 多层套圆环状、 飞镖靶状、 具孔板状、 国际象棋盘状、 田字形状、 多层套正方形环状或锯齿条纹状。 本发明中使用的掩膜的图案还可以为其他任意形状, 包括条纹状、 飞镖靶状、 田字形 状等等其他形状。
9) 一种根据第 υ 项-第 8 ) 项中任一项中所述的方法得到的液晶面板, 其中, 在所 述液晶面板的薄膜晶体管基板侧的材料上设有凹槽,在另一个对向基板上设有主间隔物和 副间隔物, 其中所述副间隔物延伸入所述凹槽内。
本发明的有益效果:
通过本发明的方法在液晶面板中形成的间隔物能够提升液晶范围 (LC Margin) , 同 时由于降低了副间隔物的宽度, 进而降低了黑色矩阵的宽度, 提升了穿透率。 通过曝光 在所述基板上形成凹槽是, 所述曝光的曝光能量为 iC lOOmJ/cm2, 优选 20-80 mj/crn2, 如 50 mJ/cm2, 如此得到的凹槽在设置间隔物后能够达到最佳的穿透率和显示效果。
