Description

显示元件
技术领域
本发明涉及将像素的多个颜色的子像素用多个开关元件分别驱动的显示元件。
背景技术
以往，在显示元件中，有对红色、绿色、蓝色这3原色的子像素加入白色的子像素而构成1个像素的技术。这样，通过对3原色的子像素加入白色的子像素，能够实现亮度的提高及耗电的降低。
此外，对3原色的子像素加入3原色之中的2个颜色的子像素和白色的子像素而构成1个像素，进而，使得白色的子像素和缺少1个的1个颜色的子像素比其他子像素大，由此抑制由于加入白色的子像素而带来的各子像素区域的开口率的减少，并且减轻白色显示时的色度向互补色系侧的偏移。该情况下，仅通过使子像素的大小不同，有时无法充分地得到通过使子像素的大小不同而带来的效果。
发明内容
本发明是鉴于上述情况做出的，实施方式的显示元件的特征在于，具备：沿规定方向配置的多个扫描线；沿与上述扫描线正交的方向配置的多个信号线；像素，具有在被上述扫描线和上述信号线所包围的区域分别形成的多个颜色的子像素，上述多个颜色之中的规定颜色的子像素的大小比其他颜色的子像素的大小大；以及多个开关元件，连接到上述扫描线和上述信号线并对上述子像素分别进行驱动，并且对应于不同大小的上述子像素而形成为不同的形状。
附图说明
图1是表示第一实施方式的显示元件的正面图。
图2是表示显示元件的像素的正面图。
图3是表示第二实施方式的显示元件的像素的正面图。
具体实施方式
实施方式的显示元件具备沿规定方向配置的多个扫描线、和沿与扫描线正交的方向配置的多个信号线。显示元件的像素具有在由扫描线和信号线包围的区域中分别形成的多个颜色的子像素，多个颜色之中的规定颜色的子像素的大小大于其他颜色的子像素的大小。显示元件的开关元件连接到扫描线和信号线，对子像素分别进行驱动，并且对应于不同大小的子像素而形成为不同的形状。
以下，参照图1及图2说明第一实施方式。
如图2所示，显示元件10中，多个像素11沿着作为第一方向的垂直方向(列方向)和正交于该垂直方向的作为第二方向的水平方向(行方向)配置为矩阵状(图2中仅示出2个像素11，但多个像素11沿垂直方向及水平方向以矩阵状配置)。
各像素11分别具有多个颜色的子像素12。本实施方式中，各像素11分别具有红色子像素(R)12R、绿色子像素(G)12G、蓝色子像素(B)12B以及白色子像素(W)12W，每1个像素11分别具有红色子像素12R和绿色子像素12G各2个、以及蓝色子像素12B和白色子像素12W各1个。即，各像素11具有6个子像素12。
红色子像素12R、绿色子像素12G以及蓝色子像素12B这3个作为第一组在水平方向上排列并邻接配置，并且，红色子像素12R、绿色子像素12G以及白色子像素12W这3个作为第二组在水平方向上排列并邻接配置，这2个组在垂直方向上排列并邻接配置。因而，各像素11在各水平方向上具有3个子像素12，在各垂直方向上具有2个子像素12。
在水平方向上邻接的像素11中，子像素12的垂直方向的位置交替反转。即，图2左侧的像素11中，第一组位于上侧，第二组位于下侧，另一方面，图2右侧的像素11中，第二组位于上侧，第一组位于下侧。并且，作为像素11整体，将在水平方向上邻接的2个像素11作为1个单位而在水平方向及垂直方向上分别重复配置。
各像素11中的多个颜色的子像素12之中，规定颜色的子像素12的大小(面积)大于其他颜色的子像素12的大小(面积)。本实施方式中，规定颜色的子像素12是蓝色子像素12B及白色子像素12W，其他颜色的子像素12是红色子像素12R及绿色子像素12G，在垂直方向上排列的蓝色子像素12B及白色子像素12W的大小(面积)大于红色子像素12R及绿色子像素12G的大小(面积)。并且，蓝色子像素12B及白色子像素12W的水平方向的宽度比红色子像素12R及绿色子像素12G的水平方向的宽度宽，从而使大小不同。
此外，显示元件10例如是可实现彩色显示的有源矩阵型的液晶面板。如图1所示，该液晶面板构成为：将阵列基板20和对置基板相互对置配置，使作为光调制层的液晶层以及将间隙保持为一定的未图示的间隔件(spacer)介于上述基板间，将其周缘部用未图示的粘接层粘贴。在液晶面板的中央部的显示区域，多个像素11沿垂直方向和水平方向以矩阵状配置。
阵列基板20具有例如具有透光性的作为绝缘性的基板的玻璃基板。在该玻璃基板的液晶层侧的主面上，多个扫描线(栅极线)21沿水平方向分别相互分离地配置，并且，多个信号线(源极线)22沿垂直方向分别相互分离地配置，这些扫描线21和信号线22以相互电绝缘的状态成为格子状。在被这些扫描线21和信号线22包围的位置，分别配置有构成子像素12的像素电极。像素电极例如由ITO等透明导电材料形成。并且，关于多个信号线22，配置为：与大小较大的蓝色子像素12B及白色子像素12W的行的区域相对应的信号线22的间隔，比与大小较小的红色子像素12R及绿色子像素12G的各行的区域相对应的信号线22的间隔宽。
在这些扫描线21与信号线22的各个交叉位置，设有用于对各子像素12进行驱动的作为开关元件的薄膜晶体管(TFT)23。
薄膜晶体管23中，在形成于玻璃基板上的绝缘膜上形成有构成薄膜晶体管23的沟道区域的半导体层27。进而，在该半导体层27上形成有绝缘膜，在该绝缘膜上形成有扫描线21以及与扫描线21电连接的栅极电极26。半导体层27由多晶硅构成，在半导体层27的一端侧形成有经过贯通孔28而与信号线22电连接的源极电极29，在半导体层27的另一端侧形成有经过贯通孔30而与构成子像素12的像素电极电连接的漏极电极31。
薄膜晶体管23对应于不同大小的子像素12而形成为不同形状。即，与大小较大的蓝色子像素12B及白色子像素12W相对应的薄膜晶体管23采用L字形状薄膜晶体管23a，与大小较小的红色子像素12R及绿色子像素12G相对应的薄膜晶体管23采用U字形状薄膜晶体管23b。
L字形状薄膜晶体管23a配置为：栅极电极26从扫描线21向子像素区域内突出，并且半导体层27为L字形状，半导体层27的沿垂直方向的一端侧配置在信号线22上，半导体层27的沿水平方向的另一端侧从栅极电极26上通过。
U字形状薄膜晶体管23b配置为：栅极电极26形成在扫描线21上，并且半导体层27为U字形状，半导体层27的沿垂直方向的一端侧配置在信号线22上，半导体层27的沿水平方向的中间部(弯曲部)向邻接的子像素区域突出，半导体层27的沿垂直方向的另一端侧从邻接的子像素区域起从栅极电极26上通过。
L字形状薄膜晶体管23a相比于U字形状薄膜晶体管23b，能够增大子像素区域的开口率(开口面积)，但在高精细化方面有制造上的制约，此外，U字形状薄膜晶体管23b相比于L字形状薄膜晶体管23a，子像素区域的开口率(开口面积)变小，但具有容易应对高精细化的特征。
另一方面，对置基板在玻璃基板上依次层叠有作为着色层的滤色器层、对置电极以及液晶层的液晶分子的取向用的取向膜等。滤色器层具有与红、绿、蓝以及白分别对应的滤色器部、和将这些滤色器部间分隔且将无用光阻断的遮光部，滤色器部分别形成在与像素电极对应的部分，构成各个子像素12。另外，关于与白对应的滤色器部，可以设为透明的滤色器部，也可以不设置滤色器部。对置电极在与像素电极对应的位置由例如ITO等透明导电材料形成。
另外，这些滤色器层及对置电极也可以根据液晶面板的模式而配置在阵列基板20侧。
并且，通过从对液晶面板进行驱动的驱动电路向扫描线21输出信号，向与扫描线21电连接的薄膜晶体管23的栅极电极26输入信号，并且通过从驱动电路向信号线22输出信号，向与信号线22电连接的薄膜晶体管23的源极电极29输入信号，该薄膜晶体管23进行开关控制，从薄膜晶体管23的漏极电极31向像素电极写入像素信号，将像素11的子像素12分别独立驱动。
在这样构成的显示元件10中，对3原色的子像素12R、12G、12B加入3原色之中的2个颜色的子像素12R、12G和白色的子像素12W而构成1个像素11，进而，通过使白色的子像素12W和缺少1个的1个颜色的子像素12B比其他子像素12R、12G大，从而能够实现亮度的提高及耗电的降低，并且，能够抑制由于加入白色的子像素12W而导致的开口率的减少，减轻白色显示时的色度向互补色系侧的偏移。进而，红色子像素12R及绿色子像素12G的大小较小者容易颜色匹配(色合わせ)。
并且，由于将薄膜晶体管23对应于不同大小的子像素12而形成为不同的形状，因此能够进一步提高通过使子像素12的大小不同而带来的效果。
即，与大小较大的蓝色子像素12B以及白色子像素12W相对应的薄膜晶体管23使用L字形状薄膜晶体管23a，与大小较小的红色子像素12R以及绿色子像素12G相对应的薄膜晶体管23使用U字形状薄膜晶体管23b。并且，L字形状薄膜晶体管23a形成为，栅极电极26从扫描线21突出，并且半导体层27沿着与扫描线21平行的方向从栅极电极26上通过，此外，U字形状薄膜晶体管23b形成为，栅极电极26配置在扫描线21上，并且半导体层27沿着与信号线22平行的方向从栅极电极26上通过。
由此，L字形状薄膜晶体管23a由于在高精细化方面存在制造上的制约，因此与大小较小的红色子像素12R以及绿色子像素12G相比，更适于大小较大的蓝色子像素12B以及白色子像素12W。蓝色子像素12B相比于其他的红色子像素12R以及绿色子像素12G而言数量较少，因此为了使色度平衡一致而需要比其他颜色的子像素大。此外，为了提高亮度，取代蓝色子像素12B而配置白色子像素12W，因此白色子像素12W的宽度与蓝色子像素12B的宽度相同。
U字形状薄膜晶体管23b虽然子像素区域的开口率变小，但是易于应对高精细化，因此适于大小较小的红色子像素12R以及绿色子像素12G。因而，通过将薄膜晶体管23对应于不同大小的子像素12而形成为不同的形状，能够进一步提高通过使子像素12的大小不同而带来的效果。
接着，在图3中示出第二实施方式。另外，对于与第一实施方式相同的构成及作用，采用同一附图标记并省略其说明。
使蓝色子像素12B的垂直方向的长度比白色子像素12W的垂直方向的长度长。此外，使蓝色子像素12B的短边及长边比红色子像素12R及绿色子像素12G的短边及长边长。进而，白色子像素12W的短边是与蓝色子像素12B的短边同等的长度，白色子像素12W的长边比其他颜色(红色、绿色、蓝色)的子像素的长边短。因而，关于这些子像素的面积，蓝色子像素12B大于红色子像素12R以及绿色子像素12G，蓝色子像素12B、红色子像素12R以及绿色子像素12G大于白色子像素12W。
此外，通过红色子像素12R、绿色子像素12G、蓝色子像素12B构成一像元(日语：絵素)、通过构成该像元的子像素以外的红色子像素12R、绿色子像素12G、白色子像素12W构成其他的一像元的本实施方式中，在由红色子像素12R、绿色子像素12G、蓝色子像素12B构成的一像元的上下左右，配置由红色子像素12R、绿色子像素12G、白色子像素12W构成的其他的一像元。
通过如上述那样地规定各子像素12R、12G、12B、12W的面积关系以及一像元的配置关系，能够使色度平衡及亮度平衡一致而提高显示品质。
通过以这样的各子像素12R、12G、12B、12W的面积关系及一像元的配置关系的规定来进行像素的高精细化时，由于红色子像素12R及绿色子像素12G的水平方向的宽度与蓝色子像素12B的宽度相比更小，因此采用U字形状薄膜晶体管23b，从而能够应对高精细化。另一方面，蓝色子像素12B为了维持与其他颜色的色度平衡及亮度平衡而使像素较大，因此采用L字形状薄膜晶体管23a，从而能够抑制开口率的降低并得到所希望的色度及亮度。白色子像素12W由于与蓝色子像素12B的水平方向的宽度相等，因此通过采用L字形状薄膜晶体管23a而能够得到所希望的亮度。
另外，显示元件10(阵列基板20)不限于液晶面板，也能够适用于有机EL显示元件、其他自发光型显示元件等显示元件。
说明了几个实施方式，但这些实施方式只是例示而并不意欲限定本发明的范围。这里所例示的实施方式能够以其他方式实施，进而，在不脱离本发明精神的范围内，能够对这些实施方式进行省略、替换、变更。这些实施方式及其变形包含在权利要求的范围及其等同范围内。
