Description

液晶显示装置
技术领域
本发明涉及一种液晶显示装置,更为详细地涉及一种在以某一数据线为中心形成在两侧的两个像素电极中,各像素电极与所述某一数据线之间的间隔形成得互不相同,而且通过所述某一数据线驱动的像素电极侧的间隔形成为小于另一像素电极侧间隔,因此能够减小遮光膜的大小,从而能够提高开口率的液晶显示装置。
背景技术
一般来讲,液晶显示装置的上部基板和下部基板在中间设置有液晶层的状态下接合在一起,并且由下部基板的下部或侧面照射背光,从而供使用者能够观看屏幕。
在所述下部基板上,由多个栅极线和多个数据线交叉排列而界定像素区,在每个像素区的一侧形成有薄膜晶体管,该薄膜晶体管用于驱动形成在相应像素区的驱动电极。
在所述上部基板中对应于每个像素区的位置上形成有滤色片,并且在每个滤色片之间区域及其他需要遮光的区域形成有遮光膜(黑矩阵)。
图1是以往的液晶显示装置的示意图。参照图1,在下部基板110中与栅极线一起界定像素区的数据线的左右两侧形成有第一像素电极112和第二像素电极113。
其中,第一像素电极112被电连接为通过位于第一像素电极112和第二像素电极113之间并且作为基准的基准数据线111驱动,第二像素电极113被电连接为通过与所述基准数据线111相邻的数据线驱动。
此时,为了提高像素区的开口率,每个像素电极最好最大限度地靠近基准数据线111而形成,但由于在像素电极和基准数据线111之间产生寄生电容(pixel-data-capacitor),会导致闪光(flicker)等问题,因此每个像素电极与基准数据线111之间隔开规定距离(a=b)而形成。
在上部基板120上形成有遮光膜121,用于充分地遮断从基准数据线111及其相邻区域,即基准数据线111和第一像素电极112之间及基准数据线111和第二像素电极113之间泄漏的光。
其中,遮光膜121被形成为其中心与基准数据线111的中心一致,从而被形成为向第一像素电极112侧延伸的部分与向第二像素电极113侧延伸的部分的长度相同。
然而,由于所述遮光膜121形成为充分地遮断从基准数据线111和第一像素电极112之间以及基准数据线111和第二像素电极113之间泄漏的光,因此具有开口率下降的问题。
发明内容
本发明是为了解决上述以往问题而提出的,其目的是提供一种液晶显示装置,该液晶显示装置在数据线的中心与配置在所述数据线的两侧的两个像素电极之间的各个间隔中,通过所述数据线驱动的像素电极和数据线中心之间的间隔形成得小于不通过所述数据线驱动的像素电极和数据线中心之间的间隔,从而能够减小遮光膜的大小,提高开口率。
上述目的可通过本发明的液晶显示装置实现,本发明的液晶显示装置,包括由多个栅极线及多个数据线交叉排列界定的多个像素区,其特征在于,包括:基准数据线,其为所述多个数据线中的某一个;第一像素电极,以所述基准数据线为中心形成在一侧,并由所述基准数据线驱动;第二像素电极,形成在所述基准数据线的另一侧,由与所述基准数据线相邻的数据线驱动;及遮光膜,形成为遮断所述基准数据线及所述基准数据线的相邻区域,所述基准数据线的中心与所述第一像素电极之间的间隔小于所述基准数据线的中心与所述第二像素电极之间的间隔。
其中,优选所述遮光膜从所述基准数据线的中心向所述第一像素电极侧及所述第二像素电极侧延伸形成,并且从所述基准数据线的中心到所述第一像素电极侧所述遮光膜的长度短于从所述中心到所述第二像素电极侧所述遮光膜的长度。
根据本发明提供如下的液晶显示装置:在数据线的中心与配置在所述数据线的两侧的两个像素电极之间的各个间隔中,通过所述数据线驱动的像素电极和数据线中心之间的间隔形成得小于不通过所述数据线驱动的像素电极和数据线中心之间的间隔,从而能够减小遮光膜的大小,提高开口率。

具体实施方式
下面,参照附图详细说明本发明的一实施例的液晶显示装置。
图2为本发明的一实施例的液晶显示装置的示意图。参照图2,本发明的一实施例的液晶显示装置由上部基板20和下部基板10在中间设置有液晶层30的状态下相互接合而形成。
其中,在下部基板10上多个栅极线和多个数据线在两者之间设置有栅极绝缘膜12的状态下交叉排列而界定出多个像素区,在所述多个像素区的上部形成有绝缘膜13。
此外,在每个像素区形成有用于在液晶层30形成电场的像素电极,在每个像素区的一侧形成有用于驱动每个像素电极的薄膜晶体管。
其中,在每个像素区中形成的像素电极以基准数据线11为中心分别位于左右两侧。
此时,形成于所述基准数据线11的右侧的像素电极被称为第一像素电极14,形成于所述基准数据线11的左侧的像素电极被称为第二像素电极15。
所述第一像素电极14通过所述基准数据线11驱动,所述第二像素电极15通过与所述基准数据线11相邻的数据线即位于左侧的数据线驱动。
此时,所述第一像素电极14由于通过所述基准数据线11被驱动,因此在第一像素电极14和基准数据线11上形成等电位,在第一像素电极14和基准数据线11之间不会产生寄生电容(pixel-data-capacitor)。
另外,所述第一像素电极14和第二像素电极15与作为其基准的基准数据线11之间的间隔互不相同,基准数据线11的中心与第一像素电极14之间的间隔小于基准数据线11的中心与第二像素电极15之间的间隔。
优选地,第一像素电极14形成为其靠近基准数据线11侧的端部最大限度地靠近基准数据线11的右侧端部,或者与基准数据线11的右侧端部一致,或者与基准数据线11重叠。
另外,在所述上部基板20中与每个像素区对应的位置上形成有滤色片,并形成有遮光膜(黑矩阵)21,用于遮断每个滤色片之间的区域即数据线和栅极线的上部及其相邻区域。
即,通过遮光膜21遮断通过基准数据线11和第一像素电极14之间的间隙A泄漏的光和通过基准数据线11和第二像素电极15之间的间隙B泄漏的光。
由于随着基准数据线11和第一像素电极14之间的间隙A比以往变短,即使将遮光膜21形成为比以往短长度C,也能遮断遮光膜21中的基准数据线11和第一像素电极14之间的间隙A,因此能够增加开口率。
本发明的权利范围并不限于上述实施例,在所附的权利要求书所记载的范围内可实现为多种形式的实施例。在不脱离权利要求书所要求保护的本发明宗旨的范围内,本发明所属技术领域的技术人员均能变形的范围也视为属于本发明的权利范围内。
