具体地，主动元件阵列基板100与对向基板110夹设有一层液晶层120，主动元件阵列基板100上像素单元99的像素电极101和对向基板110上的共通电极之间形成电场，而在二者之间的液晶层100内的液晶分子121的指向由其所感受到的电场方向所决定，改变了像素电极101的电极狭缝偏角则便对应改变了对应位置的液晶分子121的指向，在装置基板的不同曲率位置上采用不同电极狭缝102偏角的像素电极101，让液晶分子121的指向改变以补偿曲面显示器的曲率改变量，从而改善曲面显示器在不同曲率位置的色偏问题。
进一步地，像素电极101上的狭缝偏角自主动元件阵列基板100的中部向两侧对称改变。
进一步地，在主动元件阵列基板100上，每间隔一个固定的弧度，像素电极101的狭缝偏角统一改变一个角度值。
具体地，电极狭缝102的偏角随着主动元件阵列基板100的弧度变化而变化，且每个一个固定的弧度，电极狭缝102的偏角统一改变一个角度值，例如，参见图1和图5所示，图5中示意角度为俯视，视线K从基板10正前方看向基板10，挑选3个视线K中的像素电极101作为示例，如图5中的a、b、c三个像素电极101为当前指示位置基板10弧上像素电极101的主视图，当前指示位置基板10上的电极狭缝102的偏角分别是45°、43°、41°。
参见图4所示，为本申请实施例提供一种曲面显示面板400的局部主视图，即为，像素电极99的主视图，进一步地，像素电极101的配向图案包括层叠的第一配向图案B和第二配向图案B1，第一配向图案B和第二配向图案B1相同并平行错开一定距离。
具体地，目前曝光机的解析度与蚀刻制程能力的制程宽度有限，假设制程宽度极限为m，也就是说只能做出宽度为m的电极狭缝102，但若是按照本实施例中将两个配向图案层叠错开摆放，两个电极狭缝102部分重叠，则重叠的部分即为新的宽度更小的电极狭缝102，如此，能进一步增强电极狭缝102处的电场强度，进一步减少暗纹，具体错开的距离可例如为电极狭缝102宽度的一半。
进一步地，配向图案包括至少一个狭缝分布区。
具体地，配向图案可以由多个狭缝分布区构成，可根据实际需要进行设置。
进一步地，配向图案的电极狭缝为相互平行且间隔等距的光滑狭缝。
具体地，如图3所示，为本申请实施例提供的一种曲面显示面板400的局部主视图，即为，像素单元99的主视图，像素电极101表面分为A、B两个区域，B为配向图案，其包括两个电极狭缝102分布区，每条电极狭缝102相互平行，间隔等距且狭缝边缘光滑。
进一步地，配向图案面积大于像素电极的该面剩余面B的面积。
具体地，像素电极除去配向图案B的该面剩余面A在本实施例中属于相同电压下正视亮度较大的区域，亮区面积较小可以得到较佳的显示品质，例如，若该剩余面A的面积为S，则配向图案B的面积为2S-4S较佳。
参见图2所示，进一步地，对向基板110的共通电极111上设有多个配向凸起物113。
具体地，在共通电极111对应像素电极101的面上设有多个配向凸起物113，配向凸起物113的设置可以改变当前区域的作用力分布，并搭配配向图案B的设计，使该区域的液晶分子121的平均倾角与A区域的液晶分子121平均倾角不同，实现之间的液晶层120穿透率互异，以改善屏幕亮度随视角改变而急剧变化的情形。
进一步地，狭缝偏角自主动元件阵列基板100中部开始对称向两侧逐渐趋于平缓。
进一步地，像素电极101为透明导电材质制成。
具体地，使用透明导电材质制成像素电极（如ITO电极），在生成电极狭缝时能大幅度的降低暗纹的数量。
参见图6所示，为本申请实施例提供的一种曲面显示装置500，包括背光模组及曲面显示面板400，参见图1所示，曲面显示面板400可例如为液晶曲面显示面板，该曲面显示面板400包括主动元件阵列基板100、对向基板110以及夹设在主动元件阵列基板100与对向基板110之间的液晶层120，主动元件阵列基板100具有多个像素单元99，像素单元99包括主动元件104以及与主动元件104电性相连的像素电极101，像素电极101表面包括配向图案B，所述配向图案B由电极狭缝102组成，电极狭缝102相对像素电极101边缘的狭缝偏角随显示装置基板的线性变化而改变。
具体地，主动元件阵列基板100与对向基板110夹设有一层液晶层120，主动元件阵列基板100上像素单元99的像素电极101和对向基板110上的共通电极之间形成电场，而在二者之间的液晶层100内的液晶分子121的指向由其所感受到的电场方向所决定，改变了像素电极101的电极狭缝偏角则便对应改变了对应位置的液晶分子121的指向，在装置基板的不同曲率位置上采用不同电极狭缝102偏角的像素电极101，让液晶分子121的指向改变以补偿曲面显示器的曲率改变量，从而改善曲面显示器在不同曲率位置的色偏问题。

在某些实施例中，曲面显示面板400可例如为扭曲向列型液晶曲面显示面板，平面转换型液晶曲面显示面板、多象限垂直配向型液晶曲面显示面板、OLED曲面显示面板、QLED曲面显示面板或其他显示面板。
参见图4所示，为本申请实施例提供一种曲面显示面板400的局部主视图，即为，像素电极99的主视图，进一步地，像素电极101的配向图案包括层叠的第一配向图案B和第二配向图案B1，第一配向图案B和第二配向图案B1相同并平行错开一定距离。
