本申请属于显示技术领域，更具体地说，是涉及一种阵列基板、显示面板、阵列基板制作方法及显示面板制作方法。
为了应对OLED(Organic Electroluminescence Display,有机电激光显示)技术的不断冲击，LCD(Liquid Crystal Display，液晶显示)行业不断地开拓创新，发展出了dual cell panel(双液晶盒显示面板)。双液晶盒显示面板是通过两片传统的液晶面板通过OCA(光学胶)贴合形成的，可以实现真正的双倍对比度、双倍色彩显示等性能，在显示质量上可以与OLED媲美。
目前，制作双液晶盒显示面板采用的方案是：制作阵列基板——制作彩膜基板——阵列基板与彩膜基板贴合并注入液晶形成显示面板——切割显示面板——贴偏光片——连接电路板——两片显示面板堆叠贴合。
然而，上述方案制作出来的双液晶盒显示面板与传统的液晶显示面板相比较，厚度大、成本高，导致显示装置的厚度随之增大，影响了显示装置的轻薄度，并且极大地增加了显示装置的生产成本。
