附图说明
图1是示意性地示出根据本发明构思的示例性实施例的液晶显示器的剖视图。
图2示出了根据本发明构思的对比例的显示器。
图3详细示出了根据图1的示例性实施例的LCD的剖面。
图4是根据本发明构思的示例性实施例的显示器的布局图。
图5是沿线V-V'截取的图4的显示器的剖视图。
具体实施方式
在下文中,将参照附图更全面地描述本发明构思,在附图中示出了发明构思的示例性实施例。如本领域的技术人员将意识到的,在均不脱离本发明构思的精神或范围的情况下,可以以各种不同的方式修改描述的实施例。
在图中将省略与描述无关的部分以清楚地描述本发明构思,并且在整个说明书中相同或相似的构成元件将用相同的附图标记表示。
由于为了更好的理解和易于描述,任意地指示了图中示出的每种构造的尺寸和厚度,因此本发明构思不限于图中所示,并且为了清楚起见夸大了层、膜、面板、区域等的厚度。另外,为了便于描述在图中夸大了一些层和区域的厚度。
将理解的是,当诸如层、膜、区域或基底的元件被称作“在”另一元件“上”时,所述元件可以直接地在所述另一元件上,或者也可以存在中间元件。相反,当元件被称为“直接在”另一元件“上”时,不存在中间元件。词语“在…上”或“在…上方”表示位于目标部分上或下方,并且不一定表示基于重力方向位于目标部分的上侧上。
另外,除非明确地描述为相反,否则词语“包括”及变型(诸如“包含”或“含有”)将被理解为表示包括所陈述的元件但不排除任何其他元件。
另外,在本说明书中,短语“在平面上”表示从顶部观察目标部分,并且短语“在剖面上”表示从侧面观察通过垂直切割目标部分而形成的剖面。
在下文中,将参照附图详细地描述根据本发明构思的示例性实施例的液晶显示器(LCD)。
图1是根据本发明构思的示例性实施例的LCD的示意性剖视图。参照图1,根据本示例性实施例的LCD包括第一显示面板100、第二显示面板200以及设置在第一显示面板100与第二显示面板200之间的液晶层3。第一显示面板100和第二显示面板200被设置为彼此面对。
LCD包括设置有包括液晶分子31的液晶层3从而显示图像的显示区域DA,以及不包括液晶分子31的非显示区域NDA。
第一显示面板100包括第一基底110和设置在第一基底110上的第一电极191。时钟信号线178和共电压传输线177可以设置在第一基底110的非显示区域NDA中。然而,这是示例,并且未示出的各种驱动线可以设置在非显示区域NDA中。
第二显示面板200包括第二基底210、第二电极270和阻光层220。第二电极270和阻光层220设置在第二基底210上。第二电极270设置在第二基底210与阻光层220之间。即,阻光层220位于比第二电极270更远离第二基底210的位置。
参照图1,短路间隔件70和柱间隔件80设置在第一显示面板100与第二显示面板200之间。短路间隔件70和柱间隔件80设置在LCD的非显示区域NDA中。然而,多个短路间隔件70可以设置在显示区域DA中。
柱间隔件80可以与时钟信号线178叠置,并保持第一显示面板100与第二显示面板200之间的盒间隙(cell gap)。柱间隔件80可以是非导电的。短路间隔件70具有导电性,并且使共电压传输线177和第二电极270彼此连接。传输到共电压传输线177的共电压通过短路间隔件70被传输到第二电极270。
阻光层220被部分地去除,从而形成开口23,使得短路间隔件70和第二电极270通过开口23彼此接触。即,阻光层220的与短路间隔件70叠置的部分被去除,从而通过其暴露第二电极270,并且第二电极270和短路间隔件70在去除了阻光层220的部分中彼此接触。在平面图中,开口23和短路间隔件70可以具有相同的构造。短路间隔件70可以完全覆盖开口23。
参照图1,第二电极270包括作为第二电极270的断开部分的切割线271以使切割线271内侧的第二电极270和切割线271外侧的第二电极270分开。即,在形成切割线271的同时,第二电极270被部分地去除并分开。因此,第二电极270的设置在切割线271的相对侧上的部分彼此不连接。在图1中,示出了切割线271与短路间隔件70叠置,但根据示例性实施例,切割线271可以不与短路间隔件70叠置。然而,当切割线271不与短路间隔件70叠置时,切割线271可以被设置为比短路间隔件70更远离显示区域DA。
切割线271防止外部静电流入LCD的显示区域DA中。当外部静电通过LCD的边缘流入显示区域DA中时,LCD会被损坏。然而,如图1中所示,切割线271设置在第二电极270中以完全围绕显示区域DA,从外部通过第二电极270引入的外部静电不能传输到显示区域DA。
在根据本示例性实施例的LCD的情况下,第二电极270被设置为比阻光层220更靠近第二基底210。因为在阻光层220形成之前形成并部分地去除第二电极270,所以可以防止在形成第二电极270的切割线271的同时对阻光层220的损坏。
图2示出了根据本发明构思的对比例的显示器。除了阻光层220和第二电极270的位置之外,图2的显示器与图1的LCD相同,因此将省略重复的描述。参照图2,阻光层220设置在第二基底210上,然后第二电极270设置在阻光层220上。即,阻光层220设置在第二基底210与第二电极270之间。
在这种情况下,在第二电极270中形成切割线271的同时去除阻光层220的一部分,从而在阻光层220中形成开口23。第二电极270是包括透明导电氧化物的无机材料,并且阻光层220是有机材料。用于形成第二电极270的切割线271以防止静电引入的激光等也去除了设置在第二电极270下方的阻光层220。当阻光层220如图2中所示也被去除时,发生通过去除了阻光层220的区域的光泄漏。
然而,在根据本发明构思的示例性实施例的LCD中,在形成具有切割线271的第二电极270之后形成阻光层220,使得当切割第二电极270时不损坏阻光层220。因此,可以有效地防止静电的引入,而不会由于对阻光层220的损坏而导致光泄漏。
图3是根据图1的示例性实施例的详细剖视图。参照图3,LCD包括彼此面对的第一显示面板100和第二显示面板200以及设置在第一显示面板100与第二显示面板200之间的液晶层3。
首先,将描述显示区域DA。
栅电极124、共电压传输线177和时钟信号线178设置在第一基底110上。栅极绝缘层140设置在栅电极124、共电压传输线177和时钟信号线178上,并且半导体层154设置在栅极绝缘层140上,同时与栅电极124叠置。源电极173和漏电极175设置在半导体层154上。钝化层141设置在源电极173和漏电极175上。钝化层141可以省略。
滤色器230设置在钝化层141上。绝缘层180设置在滤色器230上,并且绝缘层180和滤色器230具有暴露漏电极175的接触孔185。第一电极191设置在绝缘层180上,并且第一电极191通过接触孔185接触漏电极175。然而,这是示例,并且根据示例性实施例,滤色器230可以设置在第二基底210上。
第二电极270设置在第二基底210上,阻光层220设置在第二电极270上。
在下文中,将描述非显示区域NDA。去除在第一显示面板100中与共电压传输线177叠置的栅极绝缘层140、钝化层141和绝缘层180,从而使共电压传输线177暴露。
类似地,去除在第二显示面板200中位于与共电压传输线177叠置的位置处的阻光层220,使得第二电极270暴露。
短路间隔件70设置在共电压传输线177与第二电极270之间。短路间隔件70接触共电压传输线177和第二电极270,从而将从共电压传输线177传输的共电压传输到第二电极270。
第二电极270被部分地去除,从而形成切割线271。在图3中,如箭头所示,通过切割线271防止从外部引入的静电放电(ESD)被引入显示区域DA中,从而防止ESD被传输到显示区域DA。
另外,ESD通过短路间隔件70部分地传输到共电压传输线177,因此可以分散ESD。
柱间隔件80被设置为与时钟信号线178叠置。柱间隔件80可以保持液晶层的盒间隙。然而,这是示例,可以省略柱间隔件80。另外,柱间隔件80可以被设置为不与时钟信号线178叠置。
如上所述,当第二电极270设置在阻光层220与第二基底210之间时,可以防止在用于形成切割线271以防止ESD引入的工艺过程中损坏阻光层220,从而防止光泄漏的发生。另外,时钟信号线178与第二电极270之间的距离比对比例中的距离长。这是因为阻光层220设置在时钟信号线178与第二电极270之间。因此,可以减小时钟信号线178与第二电极270之间的电容。
另外,即使在显示区域DA中,栅极线与第二电极270之间的距离也大于传统对比例中的距离。因此,在除了显示区域DA中的开口之外的区域中栅极线与第二电极270之间的电容减小。
另外,柱间隔件80需要是非导电的,但是当在形成工艺过程中柱间隔件80中包括金属性杂质时,第一显示面板100和第二显示面板200会短路。然而,在本示例性实施例中,柱间隔件80不接触第二电极270,而是接触阻光层220。因此,即使在形成工艺过程中柱间隔件80中包括金属性杂质,也可以防止第一显示面板100和第二显示面板200彼此短路。
接下来,将详细描述根据本发明构思的示例性实施例的显示器的显示区域DA的像素结构。图4是根据本发明构思的示例性实施例的显示装置的布局图,图5是沿线V-V'截取的图4的剖视图。
显示装置300包括第一显示面板100、与第一显示面板100叠置的第二显示面板200以及设置在第一显示面板100与第二显示面板200之间的液晶层3。
现在将描述第一显示面板100。包括栅极线121和栅电极124的栅极导体设置在由透明的玻璃或塑料制成的第一基底110的一侧上。
栅极线121可以在第一方向上延伸。栅极导体可以包括各种金属或导体,并且可以具有多层结构。栅极绝缘层140设置在栅极导体与液晶层3之间。栅极绝缘层140可以包括无机绝缘材料。
半导体层154设置在栅极绝缘层140的一侧上。
数据线171设置在半导体层154与液晶层3之间,并且在第二方向上延伸以与栅极线121交叉。源电极173从数据线171延伸并且可以与栅电极124叠置。漏电极175与数据线171分开,并且如图4中所示,漏电极175可以具有朝向源电极173的中心延伸的形状。
在源电极173与漏电极175之间的区域中,半导体层154的一部分可以不与数据线171和漏电极175叠置。除了这样的非叠置部分之外,半导体层154可以具有与数据线171和漏电极175的平面形状基本相同的平面形状。
一个栅电极124、一个源电极173、一个漏电极175与半导体层154一起形成一个薄膜晶体管,并且薄膜晶体管的沟道是半导体层154的设置在源电极173与漏电极175之间的区域。
绝缘层180设置在源电极173和漏电极175与液晶层3之间。绝缘层180可以包括无机绝缘材料(诸如氮化硅或氧化硅)、有机绝缘材料或低介电常数绝缘材料。
绝缘层180包括与漏电极175部分地叠置的接触孔185。
第一电极191设置在绝缘层180与液晶层3之间。第一电极191通过接触孔185与漏电极175物理地且电气地连接,并且从漏电极175接收数据电压。第一电极191可以是像素电极。
第一取向层11设置在第一电极191与液晶层3之间。
第二显示面板200包括第二基底210、第二电极270、阻光层220和第二取向层21。
第二电极270设置在第二基底210的一侧处。第二电极270可以是共电极。
阻光层220设置在第二电极270上。阻光层220与数据线171叠置,因此可以在第二方向上延伸。尽管未示出,但阻光层220还可以包括与栅极线121叠置并在第一方向上延伸的水平部分。第二取向层21设置在第二电极270与液晶层3之间。
然而,上述结构是示例,并且显示区域DA的像素结构不限于此。
虽然已经结合当前被认为是实践性的示例性实施例的内容描述了本发明构思,但应理解的是,发明构思不限于公开的实施例,而是相反,发明构思意图覆盖在权利要求的精神和范围内包括的各种修改和等同布置。
