在图中，结构相似的单元是以相同标号表示。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本发明实施例提供了一种显示面板，请参照图2，图2为本发明实施例提供的显示面板的结构示意图。该显示面板2包括第一基板21、第二基板22、第一配向膜23、第二配向膜24和支撑柱25。
第一基板21可以包括衬底以及薄膜晶体管层。其中，薄膜晶体管层用于控制显示面板2中画面的显示。衬底可以由聚酰亚胺、聚碳酸酯、聚醚砜、聚对苯二甲酸乙二醇酯、聚萘二甲酸乙二醇酯、多芳基化合物等柔性材料组成，以提高显示面板2的弯折性能。
第二基板22与第一基板21相对设置。与第一基板21类似，该第二基板22也可以采用上述柔性材料制成，以提高显示面板2的弯折性能。
第一配向膜23设置在第一基板21靠近第二基板22的一侧。第二配向膜24设置在第二基板22靠近第一基板21的一侧。该第一配向膜23和第二配向膜24用于辅助显示面板2中的液晶进行配向。
支撑柱25包括第一支撑部251，以及设置在第一支撑部251上的第二支撑部252。其中，第一支撑部251采用刚性材料制成，第二支撑部252采用柔性材料制成。第一支撑部251的高度范围为2.4微米至2.8微米，在一实施例中，可以将第一支撑部251的高度设置为2.6微米。第二支撑部252的高度范围为2.8微米至3.2微米。在一实施例中，可以将第二支撑部252的高度设置为3微米。
相较于图1中的第一支撑柱15和第二支撑柱16，本发明实施例中的第二支撑部252高度较低，可滑动范围较小，可以减小对配向膜的损害范围。
如图2或4所示，第二支撑部252的第一表面2521的面积小于第一支撑部251的第二表面2512的面积。其中，第一表面2521为与第一支撑部251相对设置的表面，第二表面2512为与第二支撑部252相对设置的表面。
上述面积设置方式，一方面可以确保支撑柱25中第一支撑部251与配向膜具有较大的接触面积，以有效固定该支撑柱25，另一方面，还通过减少第二支撑部252与配向膜之间的接触面积，来减少对配向膜的损害范围。
在一实施例中，可以将第一支撑部251和第二支撑部252均设置为圆柱形状。其中，第一支撑部251的直径范围为9.8微米至10.2微米之间。在一实施例中，第一支撑部251的直径为10微米。第二支撑部252的直径范围为4.8微米至5.2微米之间。在一实施例中，第二支撑部252的直径为5微米。
在制备上述支撑柱25的过程中，可以先沉积一层刚性材料，然后在刚性材料上沉积一层柔性材料，再进行图案化，形成该支撑柱25，即第一支撑部251和第二支撑部252一体成型。还可以分别采用弹性材料制备第二支撑部252，采用刚性材料制备第一支撑部251，再使用胶体将第一支撑部25固定在第二支撑部252上。
在一实施例中，如图3所示，第一支撑部251包括收纳部2511。第二支撑部252一端设置在收纳部2511内，当支撑柱25受到外力时，第二支撑部252被压缩，收纳于收纳部2511中。其中，在支撑柱25未受到外力时，收纳部2511除了收纳第二支撑部252的一端外，还留有收纳空间，用于在受到外力后收纳该第二支撑部252的另一端。在一实施例中，该收纳部2511可以为凹槽。
支撑柱25设置在第一配向膜23和第二配向膜24之间。在一实施例中，如图2所示，第一支撑部251固定在第一配向膜23上。在一实施例中，如图4所示，第一支撑部251固定在第二配向膜24上。
当第一支撑部固定在第一配向膜23上时，显示面板2还包括多个第一限位件26。该多个第一限位件26设置在第二基板22靠近第一基板24的一侧，并设置在第二支撑部252两侧。这样，当显示面板2受到外力，第二支撑部252发生滑动时，第一限位件26可以限制第二支撑部252的滑动范围，减少对第二配向膜24的损害范围。
第一支撑部251固定在第二配向膜24上时，显示面板2还包括多个第二限位件27。该多个第二限位件27设置在第一基板21靠近第二基板22的一侧，并设置在第二支撑部252两侧。这样，当显示面板2受到外力，第二支撑部252发生滑动时，第二限位件27可以限制第二支撑部252的滑动范围，减少对第一配向膜23的损害范围。
在一实施例中，显示面板2还包括像素层28以及黑色矩阵29。像素层28设置在第一基板21和第一配向膜23之间。该像素层28包括多个依次排列的子像素281，比如蓝色子像素、绿色子像素、白色子像素等。黑色矩阵29设置在相邻子像素281之间。该黑色矩阵29采用不透明材料制成，其可以防止透过不需要的光。
支撑柱25与黑色矩阵29相对设置。这样，即使支撑柱25滑动，造成了配向膜的损害，黑色矩阵29仍可以有效对损害进行遮挡。
在一实施例中，如图2或4所示，显示面板2还包括平坦层30，该平坦层30设置在像素层28和第一配向膜23之间。该平坦层30用于提供平坦表面。
本发明实施例的支撑柱及显示面板通过将支撑柱设置成采用刚性材料制成的第一支撑部，以及采用柔性材料制成的第二支撑部，且设置第二支撑部远离第一支撑部一侧的面积，小于第一支撑部远离第二支撑部一侧的面积，可以降低支撑柱的滑动范围，减少对配向膜的损害范围，提高了显示面板的良品率。
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。
