由于数据线 1的端部与衬底基板之间设置有有源层 8, 本实施例中, 增 高层 6的厚度例如大致等于数据线 1与有源层 8的厚度之和, 此时, 贴合区 域 2中的钝化层和非贴合区域 3中的钝化层几乎是平坦的。 在一个示例中, 增高层 6的长度等于或大于贴合区域 2的长度, 例如可 以比贴合区域 2的长度稍长, 从而在较大的面积上减少或者消除贴合区域 2 中的钝化层与非贴合区域 3中的钝化层的高度差异, 尽可能避免钝化层的脱 落。

203 )在源漏金属层上涂覆一层光刻胶;
204 )通过双色调掩模板曝光、显影, 形成对应源电极以及漏电极区域的 光刻胶完全保留区域、 对应沟道区域的光刻胶半保留区域以及对应上述区域 之外区域的光刻胶完全去除区域;
205 )通过第一次刻蚀工艺去除光刻胶完全去除区域的源漏金属层、掺杂 半导体层以及半导体层, 形成有源层 8图形;

上述本实施例的阵列基板制造方法仅仅是制造本发明所提供的阵列基板 的一种实现方法, 实际操作中, 还可以通过增加或减少构图工艺次数、 选择 不同的材料等方式改变上述具体步骤。
在上述阵列基板制造方法中, 通过在非贴合区域 3中的钝化层 5与衬底 基板之间增加增高层 6, 从而减少或者消除贴合区域 2中的钝化层与非贴合 区域 3中的钝化层的高度差异, 使贴合区域 2中的钝化层和非贴合区域 3中 的钝化层平坦化(即相互齐平),从而解决了钝化层脱落问题, 降低了接线不 良现象的发生, 提高了产品的可靠性。 本实施例还提供了一种包括上述任意一种阵列基板的显示装置。 该显示 装置例如是: 液晶显示面板、 电子纸、 OLED (有机发光二极管)显示面板、 液晶电视、 液晶显示器、 数码相框、 手机、 平板电脑等任何具有显示功能的 产品或部件。
