背景技术
近来,已经制造了具有轻重量和小尺寸的显示装置。由于诸如性能和竞争价格的优势,已经使用了阴极射线管(“CRT”)显示装置。然而,CRT显示装置具有尺寸或便携性的缺点。因此,由于诸如小尺寸、轻重量和低功耗的各种优势,诸如等离子体显示装置、液晶显示(“LCD”)装置和有机发光显示装置的显示装置已被高度关注。
LCD装置向配置的特定分子取向施加电压以改变分子取向。LCD装置根据分子取向的改变利用液晶单元的光学性质(例如,双折射、旋转偏振、二向色性和光散射)的改变来显示图像。
发明内容
当不期望的光由于液晶显示(“LCD”)装置的元件而入射在薄膜晶体管(“TFT”)的沟道区域上时,TFT的特性恶化,从而可能使得LCD的显示质量恶化。

将理解的是,前述一般描述和以下详细描述是示例性和说明性的,并且旨在提供对所要求保护的发明的进一步说明。

具体实施方式
下文中,将参照附图详细说明本发明。然而,本发明可以以许多不同的形式实施,并且不应被解释为限于本文中所阐述的实施方式。相反,提供这些实施方式使得本发明将是彻底和完整的,并且将向本领域技术人员完全传达本发明的范围。全文中相同的附图标记表示相同的元件。
将理解的是,当元件被称为“在”另一元件“上”时,其可直接地在该另一层上或它们之间可以有中间元件。反之,当元件被称为“直接在”另一元件“上”时,不存在中间元件。
将理解的是,尽管本文中术语“第一”、“第二”、“第三”等可用于描述各种元件、组件、区域,层和/或区段,但这些元件、组件、区域、层和/或区段不应受这些术语的限制。这些术语仅用于将一个元件、组件、区域、层或区段与另一元件、组件、区域、层或区段区分开。因此,在不背离本文的教导的情况下,以下讨论的第一“元件”、“组件”、“区域”、“层”或“区段”可被命名为第二元件、组件、区域、层或区段。
本文中使用的术语仅用于描述具体实施方式的目的,而不旨在进行限制。如本文中所使用的,除非内容清楚地另有所指,否则单数形式“一”、“一个”和“该”旨在包括复数形式,包括“至少一个”。“或”意指“和/或”。如本文中所使用的,术语“和/或”包括一个或多个相关所列项的任何和所有组合。还将理解的是,当在本说明书中使用术语“包含”和/或“包含有”或者“包括”和/或“包括有”时,指明所陈述的特征、区域、整数、步骤、操作、元件和/或组件的存在,但不排除一个或多个其它特征、区域、整数、步骤、操作、元件、组件和/或它们的群组的存在或附加。
另外,诸如“下”或“底部”以及“上”或“顶部”的相对术语在本文中可用于描述如图中所示的一个元件与另一元件的关系。将理解的是,除了图中描述的方位之外,相对术语旨在包括设备的不同方位。在示例性实施方式中,当附图中的一个图中的设备被翻转时,则被描述为在其它元件“下”侧的元件将然后被定位为在该其它元件“上”侧。因此,示例性术语“下”可根据图的具体方位包含“上”和“下”两个方位。类似地,当附图中的一个图中的设备被翻转时,则被描述为在其它元件“之下”或“下方”的元件将然后被定位为在该其它元件“之上”。因此,示例性术语“在……之下”或“在……下方”可包含“在……之上”和“在……之下”两个方位。
考虑到测量问题和与具体量的测量相关联的误差(即,测量系统的限制),如本文中所使用的,“约”或“大致”包括所陈述的值和如本领域普通技术人员确定的具体值的可接受偏差范围内的平均值。例如,“约”可以指在一个或多个标准偏差内,或在陈述的值的±30%、20%、10%、5%内。
除非另外限定,否则本文中使用的所有术语(包括技术术语和科学术语)具有与本发明所属领域的普通技术人员所通常理解的含义相同的含义。还将理解的是,除非本文中明确地如此限定,否则诸如那些在常用词典中限定的术语应被解释为具有与其在本发明和相关领域的上下文中的含义一致的含义,而不是将以理想或过于正式的意义来解释。
在本文中,参照理想化实施方式的示意图的剖面图示描述示例性实施方式。这样,例如由制造技术和/或公差引起的图示的形状的变化将是预期的。因此,本文中描述的实施方式不应被解释为限于如本文中所示出的区域的具体形状,而是将包括例如由制造导致的形状上的偏差。在示例性实施方式中,被示出或描述为平坦的区域可能通常具有粗糙的和/或非线性的特征。另外,示出的尖角可能是圆的。因此,在图中示出的区域本质上是示意性的,并且它们的形状并不旨在示出区域的精确形状且不旨在限制权利要求的范围。
图1是示出根据本发明示例性实施方式的显示面板的平面图。图2是沿着图1的线I-I'截取的剖视图。显示面板可包括以矩阵形式布置的多个像素。图中示出了与显示面板的一个像素对应的结构。

有源图案ACT可设置在第一绝缘层110上并且与栅电极GE重叠。有源图案ACT可包括源极区域和漏极区域以及沟道区域,其中,漏极区域和源极区域是掺杂了杂质的区域,沟道区域位于源极区域与漏极区域之间。栅电极GE可提供成足够地大,以便不仅与有源图案ACT的沟道区域重叠而且还与源极区域和漏极区域的一部分重叠。

第二绝缘层120可具有相对大的厚度以充分覆盖有源图案ACT和数据图案,使得第二绝缘层120可具有基本上水平的表面。在示例性实施方式中,第二绝缘层120可沿着有源图案ACT和数据图案的轮廓均匀地设置在第一绝缘层110上。

盖电极142可在第二方向D2上从辅助共用电极线140突出。盖电极142可与有源图案ACT的沟道区域重叠。优选地,盖电极142可完全覆盖沟道区域。由于盖电极142包括不透明金属并且覆盖沟道区域,因此其可防止光被显示面板的内部结构反射并入射至沟道区域中。因此,防止了薄膜晶体管TFT的电特性降低,并且提高了包括显示面板的显示装置的显示质量。
第三绝缘层150可设置在金属图案、共用电极130和第二绝缘层120上。在示例性实施方式中,第三绝缘层150可使用例如硅氧化物、金属氧化物等来提供。在示例性实施方式中,第三绝缘层150可使用有机材料来提供。
在示例性实施方式中,第三绝缘层150可沿着金属图案和共用电极130的轮廓均匀地设置在第二绝缘层120上。在此,第三绝缘层150可具有相对薄的厚度。在示例性实施方式中,第三绝缘层150可具有相对大的厚度以充分覆盖金属图案和共用电极130,使得第三绝缘层150可具有基本上水平的表面。
像素电极PE可设置在第三绝缘层150上。像素电极PE可通过由第二绝缘层120和第三绝缘层150限定的接触孔CNT电连接至薄膜晶体管TFT的漏电极DE。在示出的示例性实施方式中,接触孔CNT通过第二绝缘层120和第三绝缘层150被限定为单个孔。然而,在其它的示例性实施方式中,可通过第二绝缘层120限定第一接触孔,以及可通过第三绝缘层150限定比第一接触孔小的第二接触孔,使得像素电极PE可通过第一接触孔和第二接触孔电连接至漏电极DE。可在像素电极PE中限定多个狭缝状开口SL。
像素电极PE可包括透明导电材料。在示例性实施方式中,像素电极PE可使用例如透明导电材料(诸如ITO、IZO等)来提供。
相对基板可包括第二基底基板200、黑矩阵BM、滤色器CF和外覆层210。
第二基底基板200可包括具有良好的透光性、耐热性和耐化学性的材料。在示例性实施方式中,第二基底基板200可包括例如玻璃基板、石英基板、透明树脂基板等。用于第二基底基板200的透明树脂基板的示例可包括基于聚酰亚胺的树脂、基于丙烯酰的树脂、基于聚丙烯酸酯的树脂、基于聚碳酸酯的树脂、基于聚醚的树脂、包括磺酸的树脂、基于聚乙二醇对苯二甲酸酯的树脂等。
黑矩阵BM可设置在第二基底基板200上。黑矩阵BM可布置成与位于其中显示有图像的像素区域外部的区域对应,并且可阻挡光。黑矩阵BM可在第一方向D1上延伸。黑矩阵BM可设置成与栅极线GL、辅助共用电极线140、盖电极142和薄膜晶体管TFT重叠。
滤色器CF可设置在其上设置有黑矩阵BM的第二基底基板200上。滤色器CF可向传播通过液晶层LC的光提供颜色。在示例性实施方式中,滤色器CF可以是表示红颜色的红色滤色器、表示绿颜色的绿色滤色器和表示蓝颜色的蓝色滤色器。然而,本发明不限于此,并且滤色器CF可表示各种其它的颜色。滤色器CF可设置成与像素中的每一个对应,并且可布置成在相邻像素之间具有不同的颜色。滤色器CF可在相邻像素的边界处被相邻滤色器CF部分地重叠,或者滤色器CF可与相邻像素的边界间隔开。
外覆层210可设置在黑矩阵BM上。在示例性实施方式中,外覆层210可保护黑矩阵BM和滤色器CF以及使黑矩阵BM和滤色器CF平坦化,并且可使用例如丙烯酸环氧树脂材料来提供。
液晶层LC可设置在TFT基板与相对基板之间。液晶层LC可包括具有光学各向异性的液晶分子。液晶分子可由电场驱动以传播或阻挡穿过液晶层LC的光,从而显示图像。
另外,包括显示面板的显示装置还可包括安置在TFT基板的背表面上的背光组件(未示出)。从背光组件产生的光可在第二基底基板200、黑矩阵BM、滤色器CF、外覆层210等上反射,并且可能行进到有源图案ACT的沟道区域。此处,盖电极142可防止反射的光进入沟道区域。因此,可防止薄膜晶体管TFT的电特性降低,并且可提高显示装置的显示质量。
另外,栅电极GE可设置成足够大,以便不仅与有源图案ACT的沟道区域重叠而且还与源极区域和漏极区域的一部分重叠。因此,其可防止从背光组件产生的光直接地进入沟道区域。因此,可防止薄膜晶体管TFT的电特性降低,并且可提高显示装置的显示质量。
图3是示出根据本发明另一示例性实施方式的显示面板的剖视图。
参照图3,除了辅助共用电极线与盖电极的位置之外,该显示面板可与图1和图2的显示面板基本上相同。因此,将省略关于相同元件的任何进一步详细描述。
金属图案可设置在第二绝缘层120上。金属图案可包括低电阻不透明金属。金属图案可包括辅助共用电极线140(参考图1)和盖电极142。
