Description

阵列基板、液晶显示面板及液晶显示器
本申请要求于2019年08月21日提交中国专利局、申请号为201910772710.9、发明名称为“阵列基板、液晶显示面板及液晶显示器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种阵列基板、液晶显示面板及液晶显示器。
 背景技术
液晶显示面板是液晶显示器的主要元件，液晶显示面板包括阵列基板、彩膜基板、液晶层及偏光板等，彩膜基板与阵列基板的相对内侧设置有透明电极。透明电极向液晶层发射电场，液晶显示面板通过透明电极发射的电场控制液晶层中的液晶的取向，进而控制穿过液晶层的光线的偏振状态，并藉由偏光板实现光线的穿透和阻挡，从而达到显示画面的目的。
阵列基板中设置有纵横交错的金属走线，如各种数据线、栅极线和金属电极等，而这些金属走线是不透明的，因此光线只能从金属走线的间隙中通过。当光线从金属走线的边缘穿过时，金属走线的边缘及拐角会对光线的偏振方向产生影响，如改变光线的偏振方向，这些偏振方向发生改变的光线经过偏光板时会发生漏光，因此会在液晶显示面板呈现暗画面时出现亮点，即“暗态亮点”。金属走线的拐角处对光线偏振方向的影响最大，所以金属走线拐角区域出现“暗态亮点”的问题也最严重。
 技术问题
阵列基板中的金属走线的边缘和拐角处会改变从其附近通过的光线的偏振方向，导致液晶显示面板呈现暗画面时出现亮点，即“暗态亮点”，影响液晶显示面板的视觉效果和产品质量。
