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。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至图5，图3显示依照本发明的一实施例的液晶显示面板的像素的布线图，图4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5显示依照本发明的一实施例的液晶显示面板的第一子像素区及第二子像素区的示意图。第二基板120包括多条信号线120a、120b及主动组件120c，信号线120a、120b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101。主动组件120c例如为薄膜晶体管(Thin Film Transistor，TFT)，分别设置于像素101中，并电性连接于信号线120a、120b及像素101的像素电极。每一像素101具有一第一子像素区102及一第二子像素区103，其中第一子像素区102的面积优选是等于或大于第二子像素区103。每一第一子像素区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，每一第二子像素区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，因而第一子像素区102及第二子像素区103可被主干部124、126再分为四个子像素。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，第一子像素区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。而第二子像素区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，第二子像素区103优选是位于第一子像素区102的一侧，且第一子像素区102及第二子像素区103可交错排列于第二基板120上。
请参照图6及图7，图6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7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是对位于第一子像素区102，λ/4相位差列162是对位于第二子像素区103，其中零波长相位差列161的宽度是约相同或相似于第一子像素区102的宽度，λ/4相位差列162的宽度是约相同或相似于第二子像素区103的宽度，使得透过第一子像素区102的光线是对应穿过零波长相位差列161，且透过第二子像素区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(亮度)。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。
在第一子像素区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8，其显示依照本发明的一实施例的各角度的示意图。在第二子像素区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9，其显示依照本发明的一实施例的偏振光线的示意图。在第二子像素区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°)的第二子像素区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，以确保第二子像素区103的穿透率。
当液晶显示面板100的像素101显示影像时，第一电压V1是施加于第一子像素区102的像素电极，第二电压V2是施加于第二子像素区103的像素电极，且第一电压V1是高于第二电压V2(V1＞V2)。其中，第一电压V1与第二电压V2之间的电压差(V1-V2)是反比于像素101所显示的影像的灰阶值(gray-scale)。因此，当像素101显示具有较低灰阶值(低亮度)的影像时，第一子像素区102与第二子像素区103之间的电压差(V1-V2)较大。反之，当像素101显示具有较高灰阶值(高亮度)的影像时，第一子像素区102与第二子像素区103之间的电压差(V1-V2)较小。
因此，在常黑模式中，当像素101显示的影像的亮度(灰阶值)较低时，像素101中第一子像素区102与第二子像素区103之间的电压差(V1-V2)较大，使得第一子像素区102与第二子像素区103之间的亮度差异增大，而可有效地减少像素的视角问题，以改善显示质量。此像素的视角问题是指，当正面观看或斜视显示器时，像素所显示的影像效果不同。
再者，由于第一子像素区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，使得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，故第一子像素区102的显示亮度可高于二子像素区103的显示亮度。因此，通过像素101中不同子像素区102、103的夹角设计，可进一步扩大第一子像素区102与第二子像素区103之间的亮度差异，以进一步地减少像素的视角问题。
在一实施例中，第二子像素区103中的第二主干部126与第二分支部127之间的夹角θ2可为36~38度或48~52度，以有效地减少像素的视角问题。
在一实施例中，当像素101显示的影像的亮度(灰阶值)较低时(亦即当像素101显示的影像的亮度低于一预设亮度时)，第一子像素区102与第二子像素区103之间的电压差(V1-V2)可大于1伏特(V)，例如是介于1 V与3 V之间，以有效地减少像素的视角问题。
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，当像素显示的影像的亮度(灰阶值)较低时，通过像素中不同子像素区的不同分支夹角及不同电压驱动，可有效地扩大不同子像素区之间的亮度差异，以有效地减少像素的视角问题。且可通过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。
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。
