Description
本发明是申请号为201710281292.4、申请日为2017年4月26日、发明名称为“液晶显示装置”的发明的分案申请。
技术领域
本发明关于一种液晶显示装置,特别关于一种彩色滤光片于薄膜晶体管阵列型(Color filter On Array,COA)的液晶显示面板。
背景技术
随着科技的进步,液晶显示面板已经广泛地被运用在各种领域,因具有体型轻薄、低功率消耗及无辐射等优越特性,已经渐渐地取代传统阴极射线管显示装置,而应用至许多种类的电子产品中,例如行动电话、可携式多媒体装置、笔记本电脑、液晶电视及液晶屏幕等等。
对于COA架构的液晶显示面板而言,彩色滤光片(Color Filter)是设置于下基板,使得位于上基板的黑色遮光层(Black Matrix,BM)与上基板之间会有较大的厚度差,导致在黑色遮光层边缘的液晶产生倾角,在暗态时会发生漏光现象,造成对比度的下降。然而,为解决漏光问题,目前常用的作法是在黑色遮光层上覆盖一保护层(Over Coat)以降低与上基板之间的厚度差,但此作法不仅会增加制作上的成本,还会造成可靠性风险等问题。
发明内容
依据本实施例的一种显示装置,其中包含一第一基板、一栅极线设置于第一基板上,且沿着第一方向延伸、一第一电极部设置于第一基板上,沿着第一方向延伸、以及一遮光层设置于栅极线及第一电极部上,其中部分的遮光层沿着第一方向延伸,第一电极部沿一第二方向上的最小宽度小于栅极线沿第二方向的最大宽度,第一方向不同于第二方向,部分的遮光层与第一电极部至少部分重叠。
依据本实施例的一种显示装置,其中包含一第一基板、一栅极线设置于第一基板上、一数据线设置于第一基板上且与栅极线交错设置、一源极电连接数据线,源极包括第一弯曲部及第二弯曲部连接第一弯曲部,第一弯曲部形成第一凹口,第二弯曲部形成第二凹口,第一凹口与第二凹口朝向不同方向、一第一漏极及一第二漏极分别对应第一凹口及第二凹口以及第一电极区及第二电极区分别电性连接第一漏极及第二漏极,其中,第一电极区与第二电极区分别位于栅极线的两侧。

具体实施方式
以下将参照相关附图,说明依本发明实施例的一种液晶显示装置,其中相同的元件将以相同的参照符号加以说明。
参阅图1、图2、图3,图1为本实施例的液晶显示装置1的示意图,在本实施例中,液晶显示装置1包括一液晶显示面板100及一设置于液晶显示面板100一侧的背光模块200。图2为本实施例的液晶显示面板100的部分电路布局示意图,仅以其中两相邻像素(pixel N及pixel N+1)的电路布局来说明,图3则是图2的液晶显示面板100的部分电路布局与图2中液晶显示面板100沿切线A-A的剖面的位置对应示意图。
本实施例的液晶显示面板100包含一第一基板10、一与第一基板10相对设置的第二基板20、一设置于第一基板10的遮光层30、一位于第一基板10及第二基板20的显示介质40,以及设置于第二基板20的一电极层50、一栅极层60,及一晶体管单元70。
在第一基板10上设置有一导电层11及一第一配向层12,其中导电层11可为一单层或多层的透明导电层,其材质可例如为氧化铟锡(Indium Tin Oxide,ITO)、氧化铟锌(Indium Zinc Oxide,IZO)、氧化铝锌(Aluminum Zinc Oxide,AZO)、氧化锌(Zinc Oxide,ZnO)、二氧化锡(SnO2)、三氧化二铟(In2O3)、或上述的组合。导电层11可为共同电极。第二基板20上设置有一彩色滤光片(Color Filter)21及一第二配向层22。第一配向层12及第二配向层22的材料可为聚亚酰胺(polyimide,PI)。遮光层30设置于第一基板10面向第二基板20的一侧,且为一黑色矩阵(Black Matrix,BM)。显示介质40可为液晶层或有机发光层。
栅极层60设置于第二基板20上。栅极层60包括一栅极线61和一栅极62,栅极线61和栅极62为电连接,且栅极62是构成晶体管单元70的一部分。晶体管单元70包括一主动层71、一栅极62、一源极72及一漏极73,源极72电连接一数据线74。栅极线61沿着一第一方向D1延伸。数据线74设置于第二基板20上,可与栅极线61交错设置,且可沿一第二方向D2延伸。第一方向D1和第二方向D2为不同。例如,第一方向D1可与第二方向D2为垂直,但不以此为限。
电极层50设置于第二基板20上,可为一共用电极(common electrode)层,且可在整个液晶显示面板100中。电极层50可包括平行第一方向D1的第一方向电极部,和平行第二方向D2第二方向电极部。第一方向电极部包括第一电极部51和第二电极部52,分别位于栅极线61的两侧。第二方向电极部包括第三电极部53和第四电极部54。如图2所示,第一电极部51与两个第三电极部53连接,第二电极部52与两个第四电极部54连接。如图2所示,虽然第一电极部51未与第二电极部52连接,然而,第一电极部51和一第二电极部52为彼此电连接(图未示),且可为相邻,例如可位于相邻的两像素区pixel N和pixel N+1中。第一电极部51的宽度和第二电极部52的宽度可为相同或不同。第一电极部51的宽度和第二电极部52的宽度的测量方向,可为与第二方向D2平行的宽度。
栅极线61可位于第一电极部51和第二电极部52之间。主动层71及栅极线61可位于第一电极部51及第二电极部52之间。栅极层60和电极层50(共同电极层)可为相同层,亦即,可经由相同工艺制得。例如,在第二基板20上形成一金属层,再进行光刻工艺以图案化金属层,而在相同工艺中得到栅极层60和电极层50。亦即,栅极线61、栅极62、第一电极部51及第二电极部52可为相同层,经由相同工艺制得。适用的金属层,例如为铝、铜、钼、钛、铬、钨、上述金属的合金、或其组合。
参阅图2、图3,为解决遮光层30边缘的液晶产生倾角导致暗态时漏光的问题,本实施例的遮光层30投影于第二基板20上形成一投影区域P,该投影区域P重叠栅极线61,且投影区域P的二相对侧边至少部分分别位于第一电极部51及第二电极部52上。为了方便说明,投影区域P的二相对侧边分别定义为一第一侧边A及一第二侧边B。第一电极部51的二相对侧边分别定义为一第三侧边C及一第四侧边D,第三侧边C远离栅极线61,第一侧边A位于第三侧边C和第四侧边D之间。第二电极部52的二相对侧边分别定义为一第五侧边E及一第六侧边F,第六侧边F远离栅极线61,第二侧边B位于第五侧边E和第六侧边F之间。遮光层30的投影区域P的第一侧边A和第二侧边B之间的距离L1,小于第一电极部51的第三侧边C(外侧边)和第二电极部52的第六侧边F(外侧边)之间的距离L2。
依据一些实施例,遮光层30的投影区域P的第一侧边A可位于第一电极部51的范围内,但是不位于第一电极部51的第三侧边C上,也不位于第一电极部51的第四侧边D上。亦即,第一侧边A和第三侧边C的距离为大于0,且第一侧边A和第四侧边D的距离为大于0。例如,第一侧边A和第三侧边C的距离可为5um至15um之间,第一侧边A和第四侧边D的距离可为5um至15um之间。依据一些实施例,遮光层30的投影区域P的第二侧边B可位于第二电极部52的范围内,但是不位于第二电极部52的第五侧边E上,也不位于第二电极部52的第六侧边F上。亦即,第二侧边B和第五侧边E的距离为大于0,且第二侧边B和第六侧边F的距离为大于0。例如,第二侧边B和第五侧边E的距离可为5um至15um之间,第二侧边B和第六侧边F的距离可为5um至15um之间。依据一些实施例,第一电极部51或第二电极部52的宽度范围可为10um~30um。本发明中,上述第一侧边A、第二侧边B、第三侧边C、第四侧边D、第五侧边E、及第六侧边F,可为平行于第一方向D1延伸的侧边。上述两个侧边的距离,则可为平行于第二方向D2的距离。
在一实施例中,第一侧边A可位于第一电极部51的中间位置,也就是第一侧边A与第三侧边C的间距与第一侧边A与第四侧边D的间距可为相同。同样地,第二侧边B可位于第二电极部52的中间位置,也就是第二侧边B与第五侧边E的间距与第二侧边B与第六侧边F的间距可为相同。
依据一些实施例,通过将遮光层30内缩,亦即遮光层30的投影区域P的边界在电极部的范围内,使得投影区域P的二相对侧边在第一电极部51的第三侧边C与第二电极部52的第六侧边F之间,但不在第三侧边C和第六侧边F之上,亦即,遮光层30的投影区域P两侧边的距离小于两电极部的外侧边之间的距离。如此,遮光层30边缘的液晶可被相邻的第一电极部51及第二电极部52所遮蔽,如此将可有效改善遮光层30边缘漏光的问题,进而降低第一基板10与第二基板20对位开口率的变异。此外,在面板制作的过程中,可不需要特别在第一基板10上增加保护层(Over Coat),如此可降低制作成本。依据一些实施例,第一基板10上亦可设置保护层。保护层(未显示)可位于遮光层30和第一配向层12之间。
此外,依据本发明的设计,若发生工艺上的误差或其他变异导致对位偏移时,第一侧边A及第二侧边B仍能分别位于第一电极部51及第二电极部52上,进而达成本案的上述功效。依据一些实施例,第一侧边A及第二侧边B并不一定分别要在第一电极部51和第二电极部52的中间位置,只要分别位于第一电极部51的范围内及第二电极部52的范围内即可,使得第一电极部51和第二电极部52可遮蔽遮光层30的边缘。亦即,第一侧边A可位于第三侧边C与第四侧边D之间的任何位置(但不在第三侧边C和第四侧边D之上),第二侧边B可位于第五侧边E与第六侧边F之间的任何位置(但不在第五侧边E和第六侧边F之上),皆在本发明的精神与范畴内,并不以本实施例为限。
本发明将遮光层30内缩的技术可以适用于各种不同型式的液晶显示装置1,例如,垂直配向(vertical alignment,VA)型式的液晶显示装置、光配向(photo-alignment,PA)型式的液晶显示装置、边界电场切换(fringe field switching,FFS)型式的液晶显示装置、平面切换(in-plane switching,IPS)型式的液晶显示装置。例如,如图2所示,可为VA型式的液晶显示装置,像素电极82可包括多个狭缝,且经由通孔82H而与漏极73电连接。例如,图4是液晶显示面板100为低色偏(Low Color Shift,LCS)VA型式的实施态样,图4显示相同像素中,像素电极82包括两个区域:像素电极区82A和像素电极区82B,可分别由相同的栅极线61和不同的晶体管控制。栅极线61位于像素电极区82A和像素电极区82B之间。像素电极82可具有多个狭缝。第一电极部51的宽度和第二电极部52的宽度可为不同。图5则是液晶显示面板100为低色偏光配向(Photo-Alignment,PA)技术的实施态样,图5显示相同像素中,像素电极82包括两个区域:像素电极区84A和像素电极区84B,可分别由相同的栅极线61和不同的晶体管控制。栅极线61位于像素电极区84A和像素电极区84B之间。像素电极82可不具狭缝。第一电极部51的宽度和第二电极部52的宽度可为不同。
综上所述,依据一些实施例,本发明液晶显示装置1通过遮光层30内缩,使得其投影于第二基板20上所形成的投影区域P的边界在电极部的范围内,但不在电极部的侧边上。如此一来,遮光层30边缘的液晶可被第一电极部51及第二电极部52所遮蔽,可有效改善遮光层30边缘漏光的问题,且在工艺上也不需要额外增加保护层,进而可降低制作成本。
以上所述仅为举例性,而非为限制性者。任何未脱离本发明的精神与范畴,而对其进行的等效修改或变更,均应包含于权利要求范围中。
