具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，本发明提供一种液晶显示面板100。液晶显示面板100沿第一方向X及与所述第一方向X垂直的第二方向Y延伸成平板状。所述液晶显示面板100为柔性显示面板。液晶显示面板100能够沿第二方向Y弯折。在一实施例中，所述液晶显示面板100为曲面显示面板，所述曲面显示面板沿第二方向Y弯折呈曲面。
请参阅图2，液晶显示面板100包括第一基板20、与所述第一基板20相对设置的第二基板40，及形成于所述第一基板20上的间隙墙结构(Polymer  wall)30。间隙墙结构30夹设于第二基板40与第一基板20之间。当然，第一基板20与第二基板40之间还设液晶层(图未示)等结构，为节省篇幅，在此不作赘述。
间隙墙结构30为黑色光阻间隙物(Black Photo Spacer，BPS)。间隙墙结构30起到黑矩阵(Black Matrix，BM)及间隔物(Photo Spacer，PS)的双重作用。黑色光阻间隙物由黑色感光树脂或其它有机材料制成。本实施方式中，间隙墙结构30采用由黑色感光树脂或其它有机材料通过一次选择性曝光显影形成于第一基板20上，换句话说，通过一道制程/工艺于第一基板20上形成包括光阻间隙区31及黑矩阵区33的间隙墙结构30。
间隙墙结构30沿第一方向X延伸。进一步地，间隙墙结构30沿第一方向X延伸的长度，要远大于间隙墙结构30沿第二方向Y的长度。液晶显示面板100能够沿第二方向Y弯折，间隙墙结构30沿第一方向X延伸，由于间隙墙结构30与第一基板20连接面积较大，进而能够避免间隙墙结构30在弯折中受力脱离第一基板20或者于第一基板20上发生滑动。
进一步地，本实施方式中，第一基板20为阵列基板，第二基板40为彩膜基板。
第一基板20包括衬底21、电极层22、色阻层23以及保护层24。衬底21包括底面211，底面211设于所述衬底21远离所述第二基板40的一侧。所述底面211沿第一方向X及第二方向Y延伸成面。电极层22设于衬底21远离所述底面211的一侧。色阻层23设于电极层22上。色阻层23包括多个色阻231。保护层24覆盖色阻层23及电极层22。本实施方式中，保护层24的材料由有机材料制成。保护层24的材料还可以由无机材料制成，例如氧化硅(SiO)或氮化硅(SiN)。本实施例中，衬底21为柔性材料制成，其可以为PI/PET/TAC/PEN/PDMS等塑料或聚合物高分子材料。
间隙墙结构30设于保护层24上并沿第一方向X延伸。光阻间隙区31远离所述第一基板20的顶面至所述底面211的垂直距离为第一垂直距离，所述黑矩阵区33远离所述第一基板20的顶面至所述底面211的垂直距离为第二垂直距离，所述第一垂直距离要小于所述第二垂直距离。黑矩阵区33的顶面与 第二基板40之间形成空隙(图未标)。光阻间隙区31包括主光阻间隙区311及辅光阻间隙区313。
主光阻间隙区311连接于第二基板40及保护层24之间，以支撑盒厚。由于主光阻间隙区311的两端牢固连接在第二基板40及保护层24之间，在弯折液晶显示面板100时，主光阻间隙区311的两端不会产生滑动，能够有效限制液晶的混动产生偏移。进一步地，由于主光阻间隙区311不易产生偏移，有效避免了漏光和按压色偏现象。
辅光阻间隙区313设于保护层24上，辅光阻间隙区313远离保护层24的顶面与所述第二基板40之间形成空隙(图未标)，用以避免液晶显示面板100受挤压损坏。所述辅光阻间隙区313亦能防止漏光。
间隙墙结构30呈多段差结构，以间隙墙结构30从远离第一基板20的顶面到底面211的垂直距离，从高至低依次是：主光阻间隙区311、辅光阻间隙区313、黑矩阵区33。
请结合参阅图3，间隙墙结构30的数量为多个，每个间隙墙结构30沿第一方向X的延伸长度为不同。可以理解，多个间隙墙结构30沿第一方向X的延伸长度可设置为相同，其依据实际需要进行设定。
所述液晶显示面100还包括多个间隔设置的数据线(Data Line，DL)区域41，每个数据线区域41沿第一方向X延伸，所述间隙墙结构30的数量为多个，每个间隙墙结构30设于一个数据线区域41。
多个间隙墙结构30包括第一间隙墙结构301、第二间隙墙结构302、第三间隙墙结构303及第四间隙墙结构304。依沿第一方向X延伸长度从小到大依次为：第一间隙墙结构301、第二间隙墙结构302、第三间隙墙结构303及第四间隙墙结构304。在一些实施例中，第一间隙墙结构301、第二间隙墙结构302、第三间隙墙结构303及第四间隙墙结构304的数量均为多个，多个间隙墙结构30依照第一间隙墙结构301、第二间隙墙结构302、第三间隙墙结构303及第四间隙墙结构304排列顺序沿第二方向Y进行周期性排列。可以理解，多个间隙墙结构30可以包括多种长度不同的间隙墙结构，多个间隙墙结构30可以进行不同的排布。
进一步地，液晶显示面板100还包括多个子像素区域105及多个扫描线(Gate Line，GL)区域43。每个数据线区域41沿第一方向X延伸，多个数据线区域41沿第二方向Y间隔设置；扫描线区域43沿第二方向Y延伸，多个扫描线区域43沿第一方向X间隔设置。数据线区域41及扫描线区域43交叉设置围成子像素区域105。液晶显示面板100于子像素区域105设置有色阻231，液晶显示面板100于数据线区域41设数据线(图未示)，液晶显示面板100于扫描线区域41设扫描线(图未示)。间隙墙结构30形成于数据线区域41，具光阻间隙及黑矩阵双重作用，无需通过多道工艺形成黑矩阵层，进而降低了数据线区域41的间隙墙结构30的顶面至所述底面211的厚度，有利于PI液及液晶分子的流动扩散。
在一实施例中，间隙墙结构30沿第二方向Y延伸，即间隙墙结构30设于扫描线区域43，即所述液晶显示面板包括多个间隔设置的扫描线区域43，每个扫描线区域43沿第二方向Y延伸，所述间隙墙结构30的数量为多个，每个间隙墙结构30设于一个扫描线区域43。
进一步地，请再次参阅图2，第一基板20对应于色阻层23的位置会形成凸起，进而形成第一基板20的段差层结构。色阻层23及保护层24沿第三方向Z堆叠。通过色阻层23形成液晶显示面板100的色阻区域101及非色阻区域103。其中，色阻区域101对应为第一基板20设置色阻层23的区域，非色阻区域103对应为第一基板20未设置色阻层23的区域。色阻区域101对应的保护层24位置会形成凸起。
光阻间隙区311对应设置于色阻区域101，即段差层高度最大的段差平面对应光阻间隙区311，而段差层的其它位置对应黑矩阵区33。
相邻的两个色阻231连接于一起且之间未形成段差，将此区域称为第一色阻区域，两个色阻231远离所述衬底21的顶面至所述底面211的垂直距离相等。在所述第一色阻区域形成的主光阻间隙区311，不仅具有支撑盒厚的作用，还能够防止液晶混动。在制造所述液晶显示面板100时，通过具有不同透光率的光罩进行曝光显影，进而于所述第一基板20上形成多段差的间隙墙结构30，间隙墙结构30包括主光阻间隙区311、辅光阻间隙区313、黑矩阵区33。
当然，可以利用第一基板20的多段差结构来制备形成间隙墙结构30。例如，请参阅图4，相邻的两个色阻231之间，一个色阻231部分堆叠于相邻的色阻231上，进而形成一段差层结构，将此区域称为第二色阻区域。在所述第二色阻区域形成具一定高度的主光阻间隙区311。
可以理解，所述第一基板20可以为彩膜基板，所述第二基板40可以为阵列基板。
可以理解，不限定第一方向X与第二方向Y垂直，不限定第三方向Y与第一方向X垂直，不限定第三方向Y与第二方向Y垂直。
请参阅图5，液晶显示面板100还包括多个间隙子结构50，间隙子结构50形成于第一基板20上，所述间隙子结构50沿第三方向Z延伸成点柱状，多个间隙子结构50沿第三方向Z延伸的高度可以设置成不同，以分别起主光阻间隙区、辅光阻间隙区、黑矩阵区作用。
请参阅图6，本发明还提供一种液晶显示面板100的制造方法，其包括以下步骤：
S101，在第一基板20上形成间隙墙结构30。
所述间隙墙结构30采用黑色光阻间隙物通过选择性紫外曝光工艺于所述第一基板20上一次形成。所述间隙墙结构30包括光阻间隙区31及与所述光阻间隙区31连接设置的黑矩阵区33。
进一步地，所述光阻间隙区31包括主光阻间隙区311及辅光阻间隙区313。
S102，将第二基板40与所述第一基板20组立成盒形成液晶显示面板100，所述间隙墙结构30位于所述第一基板20及所述第二基板40之间。
本实施例中，第一基板20为阵列基板，第二基板40为彩膜基板。
请参阅图7，本发明另一实施例还提供一种液晶显示面板100的制造方法，其包括以下步骤：
S201，将第一基板20和第二基板40组立成盒。
具体地，所述第一基板20和所述第二基板40之间设有黑色间隔物感光单体的夹层材料。
S202，在第一基板20朝向所述第二基板40的侧面上形成间隙墙结构30。
所述间隙墙结构30用作光阻间隙及黑矩阵双重作用，所述间隙墙结构30包括光阻间隙区及黑矩阵区。
具体地，对含有黑色光阻间隙物感光单体的夹层材料选择性曝光，不同透过率区域成膜厚度不一，在所述第一基板上涂覆黑色光阻间隙物材料后曝光显影形成多段差的黑色间隔物。
本发明提供的液晶显示面板100及其制造方法，于所述第一基板20与所述第二基板40之间形成间隙墙结构30，由于间隙墙结构30与第一基板20的连接面积较大，加强了间隙墙结构30与所述第一基板20之间的连接强度，避免间隙墙结构30易脱离所述第一基板20，进而避免了漏光及色偏现象。另外，采用黑色光阻间隙物技术于所述第一基板20上通过单道制程形成不同高度的间隙墙结构30，所述间隙墙结构30具光阻间隙及黑矩阵双重作用，进而降低了成本，并且提高了遮光效果及对比度。
可以理解，以上所揭露的仅为本发明的较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
