在步骤S201中，提供TFT基板。
请一并参阅图3，所述TFT基板包括有基底20，所述基底20上形成有框胶涂布区21和配向液涂布区22。其中所述框胶涂布区21用来涂布框胶，而所述配向液涂布区22用来涂布配向液形成配向膜（PI）。所述框胶涂布区21环绕所述配向液涂布区22，并在所述框胶涂布区21与所述配向液涂布区22之间形成有一间隔220。
在步骤S202中，在所述配向液涂布区22的周围涂布形成一阻挡结构。
请参阅图4，图4为在TFT基板的基底20上形成所述阻挡结构的一较佳实施例的示意图，在该实施例中，所述阻挡结构23形成于所述配向液涂布区22和所述框胶涂布区21的间隔220处，并且所述阻挡结构23紧密地围绕着所述配向液涂布区22，以阻止配向液朝向框胶涂布区21扩散。
在具体实施过程中，所述阻挡结构23可通过喷嘴涂布的方式形成，所述阻挡结构23的材料为可硬化成型的高分子材料，尤其是可在空气中硬化成型的高分子材料，所述高分子材料优选为单一高分子材料或混合高分子材料，譬如所述高分子材料为α-氨基丙烯酸乙酯。
请参阅图5，图5为所述阻挡结构23的第一较佳实施例横截面示意图，其为沿图4中C-C'的截面示意图。
所述阻挡结构23的横截面垂直于所述阻挡结构23的长度方向A。在图5中，所述阻挡结构23相对所述基底20凸起，且所述阻挡结构23的横截面为三角形。
当然，所述阻挡结构23的横截面还可以为其它的形状，譬如方形、梯形等，只要能够阻挡所述配向液涂布区22的配向液扩散至其它区域即可，譬如请参阅图6，在图6中，所述阻挡结构23的横截面为方形。
请再回到图2。在步骤S203中，在所述配向液涂布区22涂布配向液，其中所述阻挡结构23阻挡所述配向液扩散至所述配向液涂布区22之外。
在具体实施过程中，可通过喷印技术（PI inkjet）在所述基底20表面的配向液涂布区22喷注配向液，当然也可以是利用其它技术将配向液涂布于配向液涂布区22，此处不一一列举。

在具体实施过程中，可以通过以下两种方式将所述阻挡结构23移除：
第一，对所述阻挡结构23进行加热，以熔化所述阻挡结构23，在所述阻挡结构23熔化成液体后，将该液体从所述基底20倒出，从而实现对所述阻挡结构23的移除。
第二，在所述阻挡结构23上喷洒溶剂，以使得所述阻挡结构23溶解于所述溶剂中并移除。譬如当所述阻挡结构23的材料为α-氨基丙烯酸乙酯时，可以在所述阻挡结构23喷洒酒精，以使得所述α-氨基丙烯酸乙酯溶解在所述酒精中形成液体，之后将该液体从所述基底20倒出，从而实现对所述阻挡结构23的移除。
当然还可以有其它的方式将所述阻挡结构23移除，譬如直接将所述阻挡结构23刻蚀移除等，此处不再一一列举。
本发明提供的配向膜的涂布方法是首先在基底20的配向液涂布区22的周围涂布形成一阻挡结构23，之后在所述配向液涂布区22涂布配向液，其中所述阻挡结构23阻挡所述配向液流到所述配向液涂布区22之外，最后将所述配向液固化形成配向膜24，显然，本发明配向膜的涂布方法可通过阻挡结构23阻止配向液扩散，进而可控制所形成的配向膜24的位置精度，尤其是配向膜24边界的精度，保证形成的配向膜24不会对其它区域造成不良影响。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
