请参照图1及图4，在本发明较佳实施例中，所述液晶显示面板进一步包括多个副间隔件52，多个所述副间隔件52设置在所述彩色滤光片层20顶面，且各所述副间隔件52的高度低于各所述主要间隔件51，并高于各所述导流间隔件53。副间隔件52可减缓注入在彩色滤光片层20上的PI配向液的流动速度，防止其突然流过主要间隔件51而造成污染。
在本发明一实施例中，每一个所述过孔30的周边均设置有至少一所述导流间隔件53，藉此可确保PI配向液可流入所有的过孔30之中。
请参照图6及图7，在本发明第2实施例中，所述导流间隔件53a为一椭圆柱体而具有二椭圆形棱线533a。较详细而言，每一个所述过孔30的周边均设置有多个所述导流间隔件53，且在相邻的两个所述导流间隔件53之间形成有一间隙302以用于使所述配向液通过所述间隙而流入所述过孔30中。所述椭圆柱体具有二椭圆形棱线533a以破坏PI配向液的表面张力，但不具有尖角，然而，椭圆柱体可具有较长的结构而能使二椭圆形棱线533a大范围的破坏PI配向液的表面张力。
请参照图8及图9，在本发明第3实施例中，所述导流间隔件53的外侧与过孔30的周边切齐。与过孔30的周边切齐的所述导流间隔件53，能够使PI配向液在极度靠近过孔30的情况下才被所述导流间隔件53破坏掉其表面张力， PI配向液在被破坏表面张力后又重新凝聚并形成表面张力之前即顺利流入过孔30，藉此可避免PI配向液在流入过孔30之前又重新凝聚形成表面张力而无法流入过孔30的情况。所述导流间隔件53为一截顶圆锥体而具有二圆形棱线533b。所述截顶圆锥体的二圆形棱线533b能够在碰到PI配向液时对PI配向液的表面造成压力以及形变，进而破坏PI配向液的表面张力。
与现有技术相比较，本发明液晶显示面板的设置在所述过孔30周缘301的的所述导流间隔件53，具有相对锐利的表面张力消除棱线533，可在接触PI配向液的表面时，对所述表面施压或是切入所述表面，进而破坏PI配向液的表面张力，故可避免PI配向液凝聚而不易流动的问题。因此，表面张力被破坏的PI配向液能够顺利流入过孔30中，避免因PI配向液流动不造成显示器的颜色或亮度不均的Mura现象的问题。因此，本发明液晶显示面板能够提高良率及显示品质。
