Description

一种基板及液晶显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种基板及液晶显示面板。
 背景技术
薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT- LCD)中，面板由阵列基板和彩膜基板通过ODF制程在中间灌入液晶来进行成盒，通过面板周边的非显示区域的框胶来提供面板的密封性和阵列与彩膜基板之间的接着力。为了保证面板正常使用，防止上下板之间发生剥离，框胶需保证一定大小的胶宽，一般为1300微米左右，这样才可提供足够的接着力。
随着电视面板技术日新月异的发展，当前窄边框的面板产品越来越受欢迎，这就要求电视面板周边的非显示区域要越来越窄，从而框胶的宽度也要求越来越窄，甚至要求小于300微米。在较窄的框胶宽度下，框胶无法提供给面板足够的接着力，导致上下板易剥离。
因此，现有显示面板存在窄框胶下与基板接着力不足的问题。

在一种实施例中，对上述制备的所述平坦化层80通过掩膜板进行曝光，形成所述平坦化层80的曝光区域，然后对所述曝光区域显影，在阵列基板的框胶区形成需要的凸起图形，接着刻蚀所述凸起图形形成需要的凸起81，如图2所示。
在一种实施例中，对上述制备的所述平坦化层80通过掩膜板进行曝光，形成所述平坦化层80的曝光区域，然后对所述曝光区域显影，在阵列基板框胶区形成需要的凹槽图形，接着刻蚀所述凹槽图形形成需要的凹槽82，如图3所示。

在一种实施例中，所述基板为彩膜基板，所述顶层膜层为黑色矩阵层，在框胶区内，所述黑色矩阵层的表面积大于其在衬底上正投影的投影面积。

在一种实施例中，如图11所示，所述第一基板1为阵列基板，所述第二基2板为彩膜基板，其中，在所述阵列基板1的框胶区，顶层膜层平坦化层80图案化形成有凸起；在所述彩膜基板2的框胶区，顶层膜层黑色矩阵层21图案化形成于凸起。
