然而,纳米相分离液晶技术具有光线穿透率较低的缺点,这是因为纳米相分离液晶技术通常采用完全透明导电膜(FullITO)的技术,亦即在上基板及下基板上皆形成一个完整的透明导电膜。这种透明导电膜无法利用现有技术的方式(例如制作多个凸起物(Bump)或蚀刻多个沟槽(slit)等)来使所述多个液晶分子产生一预倾角。所以,在进行输入电压时通过紫外光照射所述多个可聚合单体的步骤时,若是相邻的液晶分子的倾倒方向不一致时,光线穿透率会降低。

图3是本发明实施例的液晶面板的制造方法30的流程图。本发明提出一种液晶面板的制造方法30,包含:提供一第一基板及一第二基板(步骤31);形成一第一透明导电膜在所述第一基板上,并形成一第二透明导电膜在所述第二基板上(步骤32);形成一第一光配向层在所述第一透明导电膜上,并形成一第二光配向层在所述第二透明导电膜上(步骤33);进行一光配向步骤,提供一第一偏振紫外光予所述第一光配向层,其中所述第一偏振紫外光相对于所述第一光配向层的垂直方向的一第一预倾角度在0至90度之间,并提供一第二偏振紫外光予所述第二光配向层,其中所述第二偏振紫外光相对于所述第二光配向层的垂直方向的一第二预倾角度在0至90度之间(步骤34);提供一混合物层,夹设在所述第一光配向层及所述第二光配向层之间,其中所述混合物层包含多个液晶分子及多个反应单体(步骤35);及进行一聚合步骤,提供一紫外光予所述混合物层以形成一液晶组合物层,其中所述液晶组合物层包含所述多个液晶分子及由所述多个反应单体聚合形成的多个聚合物网络,及所述多个液晶分子与所述多个聚合物网络是分离的二个相(步骤36)。
要提到的是,本发明的液晶面板及其制造方法是通过对第一光配向层及第二光配向层进行光配向,由于所述第一光配向层及第二光配向层的垂直或水平光配向材料已预先进行光配向使其材料分子具有预倾角(0~90度),因此在进行聚合步骤时,可促使多个液晶分子具有相同倾斜的倾向,并在聚合之后提高多个液晶分子的倾倒方向的一致性,从而解决现有技术所存在的光线穿透率降低的问题。
本发明已由上述相关实施例加以描述,然而上述实施例仅为实施本发明的范例。必需指出的是,已公开的实施例并未限制本发明的范围。相反地,包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
