Description

液晶显示面板及其应用的显示装置 技术领域
本发明涉及液晶显示技术领域，特别是涉及一种液晶显示面板及其应用的显示装置。
 背景技术
液晶显示器(Liquid Crystal Display，LCD)已被广泛应用于各种电子产品中，液晶显示器大部分为背光型液晶显示器，其是由液晶显示面板及背光模块(backlight module)所组成。液晶显示面板是由两片透明基板以及被封于基板之间的液晶所构成。
目前，已发展一种垂直配向(Vertical Alignment, VA)技术，用于液晶显示面板。例如，由聚合物稳定垂直配向(polymer－stabilized alignment，PSA)制程所制造而成的聚合物稳定垂直配向型(Polymer Stabilized Vertical Alignment, PSVA)液晶显示器，其可具有广视角、高开口率、高对比及制程简单等优点。
在PSVA液晶显示器中，两透明基板之间的液晶可被掺有反应型单体(reactive monomer)，其混合于液晶分子，其中，每一透明基板的表面涂布有聚酰亚胺(polyimide，PI)，其作为配向基材。接着，当施加电压及紫外光(UV)光照射于两透明基板时，反应型单体可与液晶分子发生相分离(phase separation)现象，而在透明基板的配向基材上形成聚合物。由于聚合物跟液晶分子之间的相互作用，液晶分子会沿着聚合分子的方向来排列，因此，透明基板之间的液晶分子可具有预倾角(pre-tile angle)。
然而，目前的VA型液晶显示器容易具有色偏(Color Shift)问题，因而严重地影响液晶显示器的显示质量。为改善上述色偏问题，可改变液晶显示面板的像素结构。然而像素结构的改变，可能会导致液晶显示面板的穿透率下降。
故，有必要提供一种液晶显示面板及其应用的显示装置，以解决现有技术所存在的问题。

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
在图中，结构相似的单元是以相同标号表示。
请参照图1，其显示依照本发明的一实施例的液晶显示面板的局部剖面示意图。本实施例的显示装置可包括液晶显示面板100和背光模块(未绘示)。液晶显示面板100相对于背光模块来设置，此背光模块可为侧光式(side Lighting)背光模块或直下式入光(Bottom Lighting)背光模块，以提供背光至液晶显示面板100。液晶显示面板100可为VA型液晶显示面板，并可应用于聚合物稳定垂直配向(PSVA)型液晶显示面板、或是图案垂直配向(Pattern Vertical Alignment，PVA) 型液晶显示面板。
如图1所示，液晶显示面板100可包括第一基板110、第二基板120、液晶层130、第一偏光片140、第二偏光片150及二个四分之一波长(λ/4)图案相位差片160。液晶层130是形成于第一基板110及第二基板120之间，亦即液晶层130是位于第一基板110及第二基板120的内侧。第一偏光片140是设置于第一基板110的外侧，第二偏光片150是设置于第二基板120的外侧，λ/4图案相位差片160是分别设置于第一基板110与第一偏光片140之间，以及第二基板120与第二偏光片150之间。
如图1所示，第一基板110和第二基板120的基板材料可为玻璃基板或可挠性塑料基板，第一基板110可例如为具有彩色滤光片(Color Filter，CF)的玻璃基板或其它材质的基板，而第二基板120可例如为具有薄膜晶体管(Thin Film Transistor，TFT) 矩阵的玻璃基板或其它材质的基板。值得注意的是，在一些实施例中，彩色滤光片和TFT矩阵亦可配置在同一基板上。
请参照图2，其显示依照本发明的一实施例的PSVA型液晶显示面板的局部剖面示意图。在本实施例中，液晶显示面板100例如为PSVA型液晶显示面板，此时，液晶层130可包括反应型单体和液晶分子，反应型单体优选是光敏单体，其混合于液晶分子中。第一偏光片140是设置第一基板110的一侧，并相对于液晶层130(亦即为第一基板110的出光侧)，第二偏光片150是设置第二基板120的一侧，并相对于液晶层130(亦即为第二基板120的入光侧)。
如图2所示，在本实施例中，液晶显示面板100可为PSVA型液晶显示面板，第一基板110可包括第一电极111、第一配向层112、第一聚合物配向层113，第一配向层112及第一聚合物配向层113是依序形成于第一电极111上。第二基板120可包括第二电极121、第二配向层122、第二聚合物配向层123，第二配向层122及第二聚合物配向层123是依序形成于第二电极121上。第一电极111和第二电极121优选是以透光导电材料所制成，例如：ITO、IZO、AZO、GZO、TCO或ZnO，第一电极111和第二电极121可施加电压于液晶层130的液晶分子。在本实施例中，第一电极111例如为共同电极，第二电极121例如为像素电极。且第二电极121可具有多个区域，而每一区域所被施加的电压可为相同或不相同。配向层112、122及聚合物配向层113、123可具有一配向方向，用来决定液晶层130的液晶分子的配向，且配向层112、122及聚合物配向层113、123可具有一预倾角，此预倾角是小于90度，优选是小于60度。配向层112、122是形成于基板110、120上，聚合物配向层113、123是由反应型单体101所聚合而成，其形成于配向层112、122上。
请参照图3及图4，图3显示依照本发明的一实施例的液晶显示面板的像素电极结构的示意图，图4显示依照本发明的一实施例的液晶显示面板的主像素区及次像素区的示意图。第二基板120包括多条信号线(未显示)，其例如为栅极线及数据线，且相互垂直交错，而呈矩阵式排列，因而形成多个像素区域101。在每一像素区域101中，第二电极121具有一主像素区102及一次像素区103，其中主像素区102的面积优选是大于次像素区103。每一主像素区102的像素电极结构包括第一主干部124及多个第一分支部125，每一次像素区103的像素电极结构包括第二主干部126及多个第二分支部127。第一主干部124及第二主干部126可呈十字形图案，因而主像素区102及次像素区103可被主干部124、126再分为四个子像素区域。分支部125、127是分别由主干部124、126来倾斜地延伸出，并相互平行排列。其中，主像素区102中的第一主干部124与第一分支部125之间的夹角θ1是约等于45度，以确保液晶显示面板100的穿透率。而次像素区103中的第二主干部126与第二分支部127之间的夹角θ2是小于或大于45度，亦即夹角θ2不等于45度(θ2≠45°)，用于改善VA型液晶显示器的色偏(Color Shift)问题。
其中，夹角θ2可为介于10度与80度之间且为45度以外的角度，又例如为介于介于35度与55度之间且为45度以外的角度(如55度或40度)。又，次像素区103优选是位于主像素区102的一侧，且主像素区102及次像素区103可交错排列于第二基板120上。
请参照图5及图6，图5显示依照本发明的一实施例的液晶显示面板的λ/4图案相位差片的示意图，图6显示依照本发明的一实施例的液晶显示面板的局部剖面示意图。每一λ/4图案相位差片160包括多个零波长相位差列161及多个λ/4相位差列162，零波长相位差列161及λ/4相位差列162是交错排列，零波长相位差列161是对位于主像素区102，λ/4相位差列162是对位于次像素区103，其中零波长相位差列161的宽度是约相同或相似于主像素区102的宽度，λ/4相位差列162的宽度是约相同或相似于次像素区103的宽度，使得透过主像素区102的光线是对应穿过零波长相位差列161，且透过次像素区103的光线是对应穿过λ/4相位差列162。
依据光学原理，液晶分子的倾倒方向与偏光片的吸收轴之间的夹角为45度时，液晶显示面板可具有最大的穿透率。因此，在本发明的实施例中，通过调整光线的偏振方向及角度，可确保液晶显示面板100的穿透率。
在主像素区102中，由于光线是透过λ/4图案相位差片160的零波长相位差列161，因而λ/4图案相位差片160并不影响光线的偏振。
请参照图7，其显示依照本发明的一实施例的各角度的示意图。在次像素区103中，第一偏光片140的吸收轴可垂直于第二偏光片150的吸收轴，亦即第一偏光片140与第二偏光片150的吸收轴A之间的夹角为90度，其中二个λ/4图案相位差片160的λ/4相位差列162的慢轴C之间夹角为90度，λ/4相位差列162的慢轴C与偏光片140或150的吸收轴A之间的夹角为45度。
请参照图8，其显示依照本发明的一实施例的偏振光线的示意图。在次像素区103中，当光线是由第二偏光片150至第一偏光片140来透过液晶显示面板100时，λ/4相位差列162可先将由第二偏光片150所发出的线偏极化光转换为左手圆偏振光或右手圆偏振光，接着，此圆偏振光可通过液晶层130(亦即液晶盒)来转换为另一圆偏振光，此时，液晶层130可等效于一λ/2相位差片。接着，另一λ/4相位差列162再将圆偏振光转换为线偏振光，使得光线可通过第一偏光片140的穿透轴。因此，在液晶显示面板100中，可通过具有夹角θ2(θ2≠45°)的次像素区103来改善色偏问题，并可通过λ/4图案相位差片160的λ/4相位差列162来调整光线的偏振方向及角度，以确保次像素区103的穿透率。
请参照图9，其显示依照本发明的另一实施例的液晶显示面板的像素区域的示意图。在另一实施例中，第二基板120的这些像素区域包括多个对应不同色滤光片的像素区域R、G、B。例如，像素区域R、G、B可分别对应于红光、绿光及蓝光。像素区域R具有主像素区R1及次像素区R2，像素区域G具有主像素区G 1及次像素区G 2，像素区域B具有主像素区B 1及次像素区B 2。此时，像素区域R、G、B的主像素区R1、G1、B1的第一主干部124与第一分支部125之间可具有相同的夹角θ1(约等于45度)，而次像素区R2、G2、B2的第二主干部126与第二分支部127之间可具有不同的夹角θ2，以进一步改善色偏问题。例如，次像素区R2中的夹角θ2可为46度，次像素区G2中的夹角θ2可为47度，次像素区B2中的夹角θ2可为48度。且λ/4图案相位差片160的λ/4相位差列162可对位于次像素区R2、G2、B2，以同时确保次像素区R2、G2、B2的穿透率。
在又一实施例中，液晶显示面板可例如为图案垂直配向(PVA) 型液晶显示面板，此时，液晶显示面板可未包括聚合物配向层。
由上述可知，在本发明的液晶显示面板及其应用的显示装置中，可通过次像素区的像素电极结构来改善VA型液晶显示器的色偏问题，且可通过λ/4图案相位差片来调整光线的偏振方向及角度，以确保液晶显示面板的穿透率。因此，本发明的液晶显示面板及其应用的显示装置可改善液晶显示面板的色偏问题，并同时确保其穿透率。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
