具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
实施例1：
如图1至图5所示，本实施例提供一种液晶屏，包括第一基板和第二基板，第一基板与第二基板相互对盒，液晶层设置在第一基板与第二基板之间。
第一基板中还包括第一引线和第二引线。
作为本实施例的一种方式，第一引线为数据线D，第二引线为栅 线G，且以下均以此为例进行说明。当然，应当理解的是，如果第一引线为栅线G、第二引线为数据线D，也是可行的。
从图1中可见，在第一基板中，栅线G、数据线D交叉排列。液晶屏还包括多个用于进行显示的显示区1，而每个显示区1均位于相邻两条栅线G和相邻两条数据线D之间的区域中。每个显示区1中设置有两个子像素，每个子像素处设置有子像素电极11，该子像素电极11受栅线G和数据线D的控制，并优选位于第一基板中。
如图1所示，本实施例的液晶屏采用双数据线D的形式，即横向(沿栅线G的长度方向)相邻的两个显示区1之间设置有两条数据线D，纵向(沿数据线D的长度方向)相邻的两个显示区1之间设置有一条栅线G。换句话说，任意两条栅线G之间均设有显示区1，而数据线D则两条为一组排列在一起，两组数据线D之间设有一个显示区1。可见，在以上情况下，同一个显示区1中的两个子像素的子像素电极11可以被分别独立地控制。例如，如图1所示，每个显示区1中靠上的子像素的子像素电极11受其上侧栅线G和右侧数据线D控制，而靠下的子像素的子像素电极PA受其下侧栅线G和左侧数据线D控制。例如，当薄膜晶体管T1被子像素电极11上侧的栅线G导通时，子像素电极11由其右侧的数据线D控制并进行显示；当薄膜晶体管T2被子像素电极PA下侧的栅线G导通时，子像素电极PA由其左侧的数据线D控制并进行显示。相反，当薄膜晶体管未被栅线G导通时，对应的子像素电极不进行任何显示。以上结构是实现高分辨率显示中常用的设计，在这种设计中，同一显示区中的两个子像素电极是被分别控制的，因此提供给子像素电极11、PA的信号不同，由此两个相邻子像素电极产生的电场差异可能会更大。
显然，液晶屏中还应包括公共电极(图中未示出)，优选地，公共电极设置在第二基板上。
如图2所示，液晶屏中还包括黑矩阵2，该黑矩阵2用于遮挡栅线G、数据线D等位置，并在对应显示区1处设置有开口21，以允许光线通过。
优选地，黑矩阵2设置于第二基板中，即黑矩阵2与栅线G、数据线D设置于不同基板上，以方便其设置。彩色滤光膜可设置于第二基板上，或设置于第一基板上。
请参照图1，在本实施例中，黑矩阵2还包括向开口21内伸出的突出部，该突出部对应于该显示区1中两个子像素电极之间的间隙处。
如前所述，每个显示区1中设置有两个子像素电极，两个子像素电极之间容易产生漏光。而在本实施例中，黑矩阵2还包括对应于显示区1中两个子像素电极之间的间隙处的突出部，该突出部可遮挡住显示区1中容易漏光的位置，从而提高液晶屏的对比度，提高显示效果。
一个显示区1中的两个子像素电极沿数据线D的长度方向排列。黑矩阵2的突出部包括第一突出部221，第一突出部221设置在黑矩阵2的开口21与数据线D的长度方向平行的两侧边上，并且与同一显示区中的两个相邻子像素的子像素电极之间的间隙位置对应。第一突出部221可以具有对称的三角形或半圆形形状。第一突出部221的中心线可以与两个所述子像素之间的间隙的中心线重合。
对于本实施例中的液晶屏，一个显示区1中的两个子像素电极沿数据线D的长度方向(图中的上下方向)排列。在黑矩阵2的开口21的两侧(左右两侧)设置有第一突出部221，并且该第一突出部221设置于相邻两个子像素电极之间的间隙的位置，因此挡住了相邻子像素电极之间的漏光，提高了液晶屏的对比度，从而提高了显示效果。
第一突出部221还可以覆盖两个子像素电极的位于紧邻两个子像素电极之间的间隙的边上的顶点部。
参照图3，第一突出部221将子像素电极11和子像素电极PA的位于紧邻两个子像素电极11、PA之间的间隙的边上的顶点部覆盖住。两个子像素电极的相同侧(平行于数据线长度方向)的位于紧邻两个子像素电极11、PA之间的间隙的边上的顶点部的电场与显示区的其他部分区别最大，会导致对应区域内的液晶分子的取向不同，极易造成漏光。因此，将第一突出部221设置为覆盖两个子像素的位于紧邻两个子像素电极11、PA之间的间隙的边上的顶点部，可以有效遮蔽该位置的漏光，从而提高显示效果。
第一突出部221可以如图1所示为三角形，但其也可以如图4所示，为半圆形状。或者，第一突出部221还可以为方形、梯形等其他形状，在此不再详细描述。
子像素电极11为精细狭缝电极(fine slit electrode)，包括第一根 茎部、第二根茎部和分支部。第一根茎部平行于栅线G的长度方向，第二根茎部平行于数据线D的长度方向。黑矩阵2还可以包括第二突出部222，第二突出部222设置在每个精细狭缝电极的第一根茎部和/或第二根茎部的端点处。第一根茎部的端点靠近数据线D，第二根茎部的端点靠近栅线G，且远离两个所述子像素电极11、PA之间的间隙。
聚合物稳定的垂面排列模式(PSVA，Polymer Stablized Vertical Alignment)是广视角显示技术中重要的形式之一，而在这种形式中，子像素电极11通常为精细狭缝电极，子像素电极11中设置有多个狭缝11d。如图5所示，狭缝11d通常分为多组，每组中包括多个相互平行的狭缝11d。各个狭缝11d之间的条状的电极称为分支部11c。各组分支部11c的“根”部汇聚在一起，该汇聚的位置称为“根茎部”。例如，图5中，每个狭缝电极中包括相互垂直的第一根茎部11a和第二根茎部11b，第一根茎部11a平行于栅线G的长度方向，第二根茎部11b平行于数据线D的长度方向，两个根茎部则交叉为“+”形状。
在子像素电极为精细狭缝电极时，突出部还可以包括第二突出部222。也就是说，如图5所示，第二突出部222设置在每个精细狭缝电极的第一根茎部11a和/或第二根茎部11b的端点处。第一根茎部11a的端点靠近数据线D；第二根茎部11b的端点靠近栅线G，且远离两个所述子像素电极11、PA之间的间隙。由于精细狭缝电极的第一根茎部、第二根茎部和分支部的电场方向不同，对应第一根茎部、第二根茎部和分支部的液晶分子的取向也会有所不同，因此在第一根茎部靠近数据线D的端点处和第二根茎部靠近栅线G且远离相邻两个子像素电极之间的间隙的端点处也会存在漏光。第二突出部222可以有效遮蔽狭缝电极的第一根茎部的靠近数据线D的端点处和/或第二根茎部靠近栅线G且远离相邻两个子像素电极之间的间隙的端点处存在的漏光。
第二突出部222的中心线可以与第一根茎部11a或第二根茎部11b的中心线重合。第二突出部222可以为三角形，半圆形状，或者还可以为方形、梯形等其他形状，在此不再详细描述。
设置在栅线G的两侧且相对的两个子像素可以组成一个像素单元。例如，如图1所示的设置在栅线G的两侧的子像素电极PA和子像素电极PB构成一个像素单元。
根据本实施例的液晶屏能够有效遮蔽由子像素电极的电场(包括相邻子像素电极之间的电场；以及精细狭缝电极的第一根茎部、第二根茎部和分支部的电场)不均导致的漏光，这是因为黑矩阵2具有突出部，该突出部只设置于电场不均处。这种设置方法，可以提高开口率，从而提高液晶屏的亮度。
实施例2：
本实施例提供一种液晶屏，其具有与实施例1的液晶屏类似的结构，区别在于在本实施例中，子像素电极延伸至显示区1之外，从而与黑矩阵2部分重叠。
如图6所示，作为高分辨率显示的常见方式，子像素电极可以超出显示区1。由于黑矩阵2仅在对应显示区1处设置有开口21，显示区1可以被认为对应于黑矩阵2的开口21。因此，子像素电极就超出了黑矩阵2的开口21，从而黑矩阵2会将子像素电极的边缘覆盖，即二者部分重叠。
子像素电极还可以延伸至显示区1之外并与数据线D和/或栅线G重叠。
如图7所示，子像素电极可以超出显示区之1，并一直延伸到数据线D的上方。由于栅线G、数据线D本身就被黑矩阵2覆盖，因此子像素电极与黑矩阵2重叠。同样，子像素电极可以超出显示区1，并一直延伸到栅线G的上方(图中未示出)。
如前所述，由于黑矩阵2仅在对应显示区1处设置有开口，因此黑矩阵2会将子像素电极的边缘覆盖。
一般来说，子像素电极的边缘电场作用会导致液晶分子的排列偏离预定的取向方向，造成漏光。由于黑矩阵2将子像素电极的边缘覆盖，因此可以有效遮蔽由相邻子像素电极之间的电场导致的漏光，同时，还可以提高开口率，从而提高液晶屏的亮度。
实施例3
本实施例提供一种显示装置，包括实施例1或2中的液晶屏。
本实施例提供的显示装置适用于液晶电视、户外液晶显示屏等显示领域，其通过采用上述液晶屏，可以有效避免相邻子像素电极之间的电场导致的漏光，同时提高液晶屏的亮度，使液晶屏的显示效果更优化。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也被视为落入本发明的保护范围。
