Description

现今显示技术领域，液晶显示器(Liquid  Crystal  Display，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。如：液晶电视、移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕等，在平板显示领域中占主导地位。
LCD 电视（LCD TV）产品目前大量使用VA型（垂直配向型）液晶显示面板技术，如图1所示，VA型（垂直配向型）液晶显示面板包括扫描线21、数据线41、阵列基板侧公共电极22（Acom，在本申请中描述作为第一公共电极）、多个扫描线21和多个数据线41交叉设置形成多个子像素101，黑色矩阵71覆盖阵列基板侧公共电极22（Acom，第一公共电极）沿第一方向（图1中为水平方向）延伸的部分和扫描线21，阵列基板侧公共电极（Acom，第一公共电极）的作用是：1）实现主区子像素和次区子像素的电压不同，从而达到八畴显示效果；2）与像素电极形成存储电容，维持一帧时间的显示。目前的超高清（8K）显示面板中，在设计阵列基板侧的公共电极时金属拐角部（图1中的虚线圈内）会设计成直角，但是在实做时由于曝光机台的限制，阵列基板侧公共电极（Acom，第一公共电极）的拐角部不能完全曝出，阵列基板侧公共电极（Acom，第一公共电极）的金属拐角会曝出圆弧形、或多边形、或三角形的近似形状，例如图1中阵列基板侧公共电极22（Acom，第一公共电极）呈现虚线框内的拐角部220  进而拐角部220会在显示面板的暗态容易产生反射发生漏光，从而导致显示面板的对比度下降，影响用户观看体验，特别的针对超高清（8K）显示面板来说，由于显示面板的像素数量更多，拐角部220的漏光会加剧，从而导致显示面板的对比度下降更严重。
因此，亟需一种显示面板以解决上述技术问题。
