根据本申请的一个方面,提供了一种显示面板10,包括第一基板11、第二基板12、液晶层13、第一取向层14、端子以及沟槽。
在本申请的实施例中,所述第一基板11为阵列基板,所述第二基板12为彩膜基板。
通常的,阵列基板包括阵列设置的薄膜晶体管,彩膜基板包括彩色滤光片以及黑色矩阵。
所述第一基板11包括第一区11a和第二区11b。
在显示面板10的制作过程中,需分别进行彩膜基板和阵列基板的制备,然后再将彩膜基板和阵列基板进行对位成盒。但是由于阵列基板的尺寸大于彩膜基板的尺寸。因此在彩膜基板与阵列基板对位成盒后,阵列基板分为与彩膜基板相对应的第一区11a以及第一区11a外围的第二区11b。
即彩膜基板在阵列基板上的正投影所覆盖的区域为第一区11a,阵列基板上第一区11a外围的区域为第二区11b。
第一基板11与第二基板12相对设置,所述第二基板12的位置和图案与所述第一区11a的位置和图案相对应。
液晶层13,设置在所述第一基板11与所述第二基板12之间。通过第一基板11和第二基板12的电压改变进而控制液晶层13内液晶的偏转方向,进而获得预期亮度的出射光。
第一取向层14,设置在所述第一基板11靠近所述液晶层13的一侧表面,所述第一取向层14位于所述第一区11a。
液晶层13内的液晶是一种液态晶体,自然滴落在液晶盒里的液晶分子是杂乱的,不符合液晶盒设计的液晶分子排列要求。因此,在需要的阵列基板和彩膜基板上涂布一层液晶分子的取向层(通常采用聚酰亚胺),在取向层上面摩擦出方向性的沟道,此界面处液晶分子就被这些沟道“锚定”而取向。
在本申请的实施例中,显示面板10还包括第二取向层,所述第二取向层设置在所述第二基板12靠近所述液晶层13的一侧表面。
所述端子设置在第二区11b,通常具有相关的电学特性,在受到聚酰亚胺液覆盖时,会导致电学效果变差,进而导致显示面板10的内部接触线路不良。
在进行第一取向层14制备时,聚酰亚胺液的涂布区域不能超过所述第一区11a,更不能涂至第二区11b的端子处,但是由于端子与第一取向层14之间的间距非常短,在进行第一取向层14涂布时,聚酰亚胺液的涂布精度无法精确控制,进而导致端子会受到聚酰亚胺液的污染,进而导致产品的良品率降低。
为了避免上述问题的发生,本申请的显示面板10还包括设置在所述端子与所述第一取向层14之间的沟槽,所述沟槽用以阻挡所述第一取向层14污染所述端子。在进行第一配向层制备过程中,当聚酰亚胺液往所述端子蔓延时,设置在第一取向层14与端子之间的沟槽会储存大量的聚酰亚胺液,可在一定程度上阻挡第一取向层14污染所述端子。
在本申请的实施例中,所述端子包括银胶点28。
进一步的,所述银胶点28设置在第一基板11的第二区11b,用以导通阵列基板和彩膜基板。
在本申请的实施例中,所述端子包括靠近所述第一取向层14的第一边15a,所述第一边15a与所述第一取向层14的边缘平行设置的第一边15a;
所述沟槽包括设置在所述端子外围的第一沟槽161,所述第一沟槽161至少围绕所述第一边15a。所述端子的第一边15a为最易受到聚酰亚胺液污染的一边,在端子的第一边15a外围设置第一沟槽161能够高效的阻挡聚酰亚胺液对端子的污染。
具体的,所述第一沟槽161位于所述第二区11b。
在本申请的实施例中,所述沟槽包括设置在所述第一取向层14外围的第二沟槽162;
其中,所述第二沟槽162的长度大于所述第一边15a的长度。
具体的,所述第二沟槽162位于所述第一区11a。即所述第二沟槽162位于所述第一区11a内未被所述第一取向层14涂布的区域。
在本申请的实施例中,所述第一沟槽161和所述第二沟槽162即可以单独设置,也可以同时设置。
在一种实施例中,所述第一基板11同时设置有第一沟槽161和第二沟槽162。
在一种实施例中,所述第一基板11仅设置有第一沟槽161而未设置第二沟槽162。
在一种实施例中,所述第一基板11仅设置有第二沟槽162而未设置第一沟槽161。
所述第一沟槽161和第二沟槽162的设置具体可根据第一基板11的结构需求而灵活变动。
在本申请的实施例中,所述第一沟槽161与所述第一边15a平行。
在本申请的实施例中,所述第一基板11为阵列基板,所述第二基板12为彩膜基板,所述阵列基板包括基底21、间绝缘层22、第一金属23、平坦化层24、钝化层25、第一过孔、第一电极26和银胶27。
在本申请的实施例中,所述基底21包括衬底以及设置在衬底上的栅极金属。
所述间绝缘层22设置在所述基底21的表面。
所述第一金属23设置在所述间绝缘层22的表面,所述第一金属23包括源漏极金属。
所述平坦化层24设置在所述第一金属23的表面。
所述钝化层25设置在所述平坦化层24的表面。
所述第一过孔贯穿所述平坦化层24和所述钝化层25。
所述第一电极26设置在所述钝化层25的表面,所述第一电极26通过所述第一过孔与所述第一金属23连接。
所述银胶27设置在所述第一电极26表面。
在本申请的实施例中,所述银胶点28包括第一金属23、第一电极26和银胶27。
在本申请的实施例中,所述平坦化层24的膜厚可以为25000埃米。由于阵列基板中平坦化层24的较厚,因此选择在平坦化层24内设置沟槽,以提高沟槽的深度。
在本申请的实施例中,所述沟槽贯穿所述平坦化层24和所述钝化层25。
根据本申请的另一个方面,本申请还提供了一种显示装置,包括偏光片和所述的显示面板10,所述显示面板10包括:
