本发明提供一种液晶显示面板及曲面显示设备，曲面显示设备包括所述的液晶显示面板及背光模组，所述背光模组为液晶显示面板提供光源。曲面显示设备可以为曲面显示器或者曲面移动设备。液晶显示面板可以是可变性的柔性面板，当然也可以是曲形面板。
请参阅图1与图2，本实施例中，所述液晶显示面板为柔性面板。所述液晶显示面板包括阵列基板11、彩膜基板12及夹持于彩膜基板12与阵列基板11之间的液晶层13，所述阵列基板11的像素电极19表面设有数个凹部191及数个平台192，所述数个凹部191及数个平台192交叉设置并共同构成矩阵(也就是数个凹部191及数个平台192在同一个矩阵内均匀的交叉设置)，所述凹部191位于两个相连接的像素170之间连接位置，也可以是像素电极与漏极连接的位置，根据具体情况，只要是凹部又不影响整个阵列基板设计即可。所述凹部191设有第一支撑体24，所述平台192设有第二支撑体25，所述第一支撑体24凸出所述平台192的高度大于第二支撑体25凸出所述平台192的高度，所述第一支撑体24及第二支撑体25伸入液晶层13，用于支撑于所述彩膜基板12与阵列基板11之间。进一步的，所述彩膜基板12上朝向液晶层设有矩阵排列的黑矩阵单元，黑矩阵单元与所述第一支撑体及第二支撑体正向相对(图未示)。早液晶显示面板弯曲状态下，即使因为两个基板的变形导致第一支撑体24及第二支撑体25左右移动，亦不会出现液晶配像不均的问题。
请参阅图2，所述阵列基11包括栅极绝缘层14能形成与栅极绝缘层14的TFT开关15，覆盖所述栅极绝缘层14及TFT开关15的第一绝缘层16、层叠于第一绝缘层16的色阻层17及覆盖所述色阻层17的第二绝缘层18，所述像素电极层19叠于第二绝缘层18上。TFT开关15包括被栅极绝缘层覆盖的栅极151、源极152以及漏极153，其中，栅极151形成基板111的表面，栅极绝缘层14覆盖于栅极151表面，有源层154形成于栅极绝缘层14表面，源极152与漏极153间隔预定距离形成于有源层154表面，其中，所述预定距离即为源极141和漏极142之间的导电沟道。漏极153电性连接像素电极19。像素电极29与TFT开关15通过半导体工艺形成于基板上。可理解，阵列基板11是利用五次光刻工艺于透明玻璃基板上形成，其中，基板有可能为透明的石英基板、玻璃基板或是塑胶基板。像素电极Px可采用氧化铟锡(Indium-Tin-Oxide，ITO)。
进一步的，所述平台192为所述像素电极19的平面部分，(也就是对应的R、G、B单个色阻的部分为平台)所述凹部191为像素电极19位于两个相邻的色阻的交叉部分，且凹部191低于所述平台192。
本发明所述的液晶显示面板10的液晶层内阵列基板11与彩膜基板12之间的支撑物采用高低不同的第一支撑体及第二支撑体，相较于现有技术的支撑体设于彩膜基板上而对顶的是阵列基板的色阻，液晶面板在发生弯曲时，上下两个基板会发生相对形变，使得某些区域支撑体对顶的位置向色阻交叠区域移位，而色阻交叠区域的色阻厚度会比色阻平坦区要高上许多，部分支撑体顶到阵列基板侧地势较高的地方，导致局部液晶盒产生变异这些技术问题来说，本申请将即把彩膜基板12侧的支撑体拿掉，将支撑体做到阵列基板侧，因第一支撑物与第二支撑物对顶是彩膜基板侧的黑矩阵，因黑矩阵地形平坦，亦不会出现变异、不均的问题。更进一步的，将第一支撑体24设置于色阻170之间的凹部191内，将凹部填充，使阵列基板的像素电极层平坦，避免影响液晶的扩散均匀度，保证了液晶配像良好的技术问题，在液晶显示面板弯曲状态下保证了显示质量。
请参阅图3，本发明还提供一种上述液晶显示面板制作方法。所述方法包括：
如图4所示，步骤S1，提供一形成有像素电极的阵列基板，即上述阵列基板，且像素电极19表面形成有平台192及低于所述平台192的凹部191；所述平台为所述像素电极的平面部分，所述凹部191为像素电极形成于色阻层内两侧同色系像素的交叉部分。
具体的，提供一基板111，于基板111上形成薄膜晶体管，也就是TFT开关，在所述薄膜晶体管上形成色阻层17及绝缘层(第二绝缘层18)、在所述绝缘层上形成像素电极19。
步骤S2，提供形成有不透光区31、第一透光区32及第二透光区33的半色调掩膜板30，其中第一透光区32的透光率大于第二透光区33的透光率。
步骤S3，在所述阵列基板的像素电极19上形成第一光阻层(图未示)，并使所述半色调掩膜板的第一透光区32与所述凹部191正对，所述第二透光区33与所述平台192正对；
如图5所示，步骤S4，以半色调掩膜板30作为光掩膜板光照所述第一光阻层，在所述凹部191位置形成第一光阻凸起201，在所述平台192位置形成第二光阻凸起202；第一光阻凸起201及第二光阻凸起202之间为像素电极19 表面且与所述半色调掩膜板30的不透光区31正对。所述第一光阻层为负型光阻材料形成，光照时，不透光区31所对应的第一光阻层部分被光照去掉，第一透光区32的透光率大于第二透光区33，由于光的穿透率越大，去除的光阻部分越少，所述对应的第一光阻凸起201高度高于第二光阻凸起202。
步骤S5，在形成有第一光阻凸起201及第二光阻凸起202的像素电极上形成第二光阻层；
如图2所示，步骤S6，使所述半色调掩膜板30的第一透光区32与所述第一光阻凸起201正对，所述第二透光区33与所述第二光阻凸起202正对并进行光照，使所述第一光阻凸起形成第一支撑体24，使第二光阻凸起202形成第二支撑体25。具体为，对第二光阻层进行光照后在所述第一光阻凸起201上形成第三光阻凸起203，在第二光阻凸起202上形成第四光凸起204，所述第一光阻凸起201与第三光阻凸起203形成所述第一支撑体24，第二光阻凸起202与第四光凸起204形成所述第二支撑体25。第一支撑体24和第二支撑体25在两次形成过程中采用材料是一样的。
本方法还包括提供一彩膜基板，所述彩膜基板朝向所述阵列基板的表面设有黑矩阵，黑矩阵的黑矩阵区域对应所述第一支撑体24及第二支撑体25，
将阵列基板与彩膜基板对合密封液晶层，构成液晶显示面板。
本方法中，将支撑物(第一支撑体24、第二支撑体25)会使用半色调掩膜板光罩代替传统支撑物使用的普通光罩，使得支撑物的尺寸更容易控制，支撑物上下底差异变小，不但解决了弯曲状态下支撑物移位的显示问题，同时支撑物制程良率问题也得到极大改善。
以上所述是本发明的优选实施例，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
