附图说明
通过结合附图进行的以下描述,本发明的实施例的上述和其它方面、特点和优点将变得更加清楚,附图中:
图1根据本发明的实施例的液晶面板的结构示意图;
图2是根据本发明的实施例的阵列基板的平面图;
图3是根据本发明的实施例的阵列基板的侧视图;
图4是根据本发明的实施例的阵列基板的制作方法的流程图。
具体实施方式
以下,将参照附图来详细描述本发明的实施例。然而,可以以许多不同的形式来实施本发明,并且本发明不应该被解释为限制于这里阐述的具体实施例。相反,提供这些实施例是为了解释本发明的原理及其实际应用,从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中,为了清楚器件,夸大了层和区域的厚度。相同的标号在附图中始终表示相同的元件。
图1根据本发明的实施例的液晶面板的结构示意图。
参照图1,根据本发明的实施例的液晶面板包括:对盒设置的阵列基板(Array基板)100和彩膜基板(CF基板)200,以及夹设于阵列基板100和彩膜基板200之间的液晶层300,其中,液晶层300中具有若干液晶分子。彩膜基板200通常包括由红(R)滤光片、绿(G)滤光片、蓝(B)滤光片构成的彩色滤光片、黑色矩阵、配向膜等。更加详细地彩膜基板的结构请参照相关的现有技术,这里不再赘述。
以下对根据本发明的实施例的阵列基板100进行详细说明。图2是根据本 发明的实施例的阵列基板的平面图。图3是根据本发明的实施例的阵列基板的侧视图。图4是根据本发明的实施例的阵列基板的制作方法的流程图。在图2中,为了清楚地示出漏极160a、源极160b以及与源极160b连接的数据线160c的结构,未示出钝化层170及形成在钝化层170中的过孔171。钝化层170及过孔171的结构请参照图3。
参照图2至图4,在步骤S410中,提供一基板110。这里,该基板110可以是透明的玻璃基板或者树脂基板。
在步骤S420中,在基板110上形成栅极线120a以及与栅极线120a连接的栅极120b。这里,可对形成在基板110上的金属层(未示出)进行曝光、显影,从而形成栅极线120a和栅极120b。也就是说,栅极线120a和栅极120b由金属材料制成。
在步骤S430中,在基板110上形成覆盖栅极线120a和栅极120b的栅极绝缘层130。这里,栅极绝缘层130可以由SiOx、SiNx或者二者的混合物形成。
在步骤S440中,在栅极绝缘层130上形成有源层140。这里,有源层140可以由非晶硅(a-Si)形成。进一步地,也可以对非晶硅的上层部分进行掺杂,从而使有源层140的下层部分为非晶硅,上层部分为掺杂非晶硅。
进一步优选地,有源层140和栅极120b正相对设置,但本发明并不限制于此。
在步骤S450中,在栅极绝缘层130上形成将有源层140暴露的有机层150。
进一步地,有机层150将有源层140暴露的实现方法为:在有机层150中形成通孔151,使通孔151的宽度大于有源层140的宽度,以将有源层140及其周围的栅极绝缘层130暴露。
在步骤S460中,在有机层150上形成漏极160a、源极160b以及与源极160b连接的数据线160c;其中,漏极160a和源极160b分别与有源层140接触,并且数据线160c与栅极线120a重叠在一起。进一步地,从空间上看,数据线160c与栅极线120a上下平行且重叠在一起。
进一步地,漏极160a和源极160b分别与有源层140接触的具体实现方法为:
使在有机层150上的源极160b经过由通孔151暴露的栅极绝缘层130而延伸至有源层140的一端之上,并使在有机层150上的漏极160a经过由通孔151暴露的栅极绝缘层130而延伸至有源层150的另一端之上。
在步骤S470中,在有机层150上形成覆盖漏极160a、源极160b以及数据线160c的钝化层170。这里,钝化层170可以由SiOx、SiNx或者二者的混合物形成。
在步骤S480中,在钝化层170中形成过孔171,其中,过孔171暴露漏极160a。进一步地,过孔171暴露漏极160a的部分。
在步骤S490中,在钝化层170上形成像素电极180;其中,像素电极180通过过孔171接触漏极160a。
综上所述,与现有技术的数据线与栅极线正交设置相比,根据本发明的实施例的阵列基板及其制作方法,通过使数据线与栅极线重叠在一起,减小栅极线和数据线所占基板的空间,从而实现开口率的提升。
虽然已经参照特定实施例示出并描述了本发明,但是本领域的技术人员将理解:在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下,可在此进行形式和细节上的各种变化。
