目前柔性LCD制作过程中柔性衬底广泛使用聚酰亚胺（Polyimide，PI），但是由于聚酰亚胺对紫外光的吸收，在液晶显示器的成盒过程中，采用紫外光对框胶103进行固化，容易造成框胶103固化异常，影响产品品质，甚至造成产品失败。基于此，本发明实施例提供一种显示面板及其制备方法、显示装置，以下分别进行详细说明。
首先，本发明实施例中提供一种显示面板，显示面板包括：第一柔性衬底101；第二柔性衬底102，第二柔性衬底102与第一柔性衬底101相对设置；框胶103，形成于第一柔性衬底101和第二柔性衬底102之间；其中，第一柔性衬底101和第二柔性衬底102中至少一种为无色透明的聚酰亚胺材料。
如图1所示，为本发明实施例中显示面板的一个实施例结构示意图，显示面板包括：第一柔性衬底101，其中，第一柔性衬底101可以进行弯折，使得采用了第一柔性衬底101的显示面板可以进行弯曲，实现柔性屏功能；第二柔性衬底102，第二柔性衬底102与第一柔性衬底101相对设置，在液晶成盒工艺中，将阵列基板和彩膜基板进行对称贴合，使得第二柔性衬底102和第一柔性衬底101对称设置的；框胶103，形成于第一柔性衬底101和第二柔性衬底102之间，在液晶成盒工艺中，当阵列基板和彩膜基板进行对称贴合后，需在阵列基板和彩膜基板之间的边框处填充框胶103，并采用紫外光固化框胶103，防止盒内的液晶渗漏或被污染；其中，第一柔性衬底101和第二柔性衬底102中至少一种为无色透明的聚酰亚胺材料，其中，第一柔性衬底101或第二柔性衬底102均可采用了无色透明材料，在面板制作过程，其中采用紫外光固胶对液晶层进行封装时，可以有效的增大紫外光对柔性衬底的穿透率，从而充分的将紫外光固胶进行固化，有效的降低了显示面板后期制作过程中液晶分子外漏的风险。
本发明实施例提供一种显示面板，显示面板包括：第一柔性衬底101；第二柔性衬底102，第二柔性衬底102与第一柔性衬底101相对设置；框胶103，形成于第一柔性衬底101和第二柔性衬底102之间；其中，第一柔性衬底101和第二柔性衬底102中至少一种为无色透明的聚酰亚胺材料，本发明通过采用无色透明的聚酰亚胺材料作为衬底，使得在紫外线固化框胶103时，紫外线可以有效穿透衬底，从而保证框胶103固化充分，以防止出现渗透液晶现象，提高产品质量。
在上述实施例的基础上，在本申请的另一个实施例中，无色透明的聚酰亚胺材料是由1,2,3,4-环己烷四酸二酐作为二酐单体或共聚单体，与二元伯胺缩聚反应合成。
本实施例中，第一柔性衬底101包括显示区和非显示区，第一柔性衬底101背离第二柔性衬底102的一侧的显示区的表面设置有第一紫外光吸收层。
如图1所示，第一柔性衬底101包括显示区201和非显示区202，第一柔性衬底101背离第二柔性衬底102的一侧的显示区的表面设置有第一紫外光吸收层203。
在上述实施例的基础上，在本申请的另一个实施例中，第一紫外光吸收层中掺杂有吸光胶囊水杨酸脂类化合物、苯酮类化合物、苯并三唑类化合物及丙烯腈类化合物中的一种或多种。例如，本申请中第一紫外光吸收层或第二紫外光吸收层均可以为掺杂有吸光胶囊的无色PI，但不限于此，第一紫外光吸收层和第二紫外光吸收层需保证能将300~343nm紫外光吸收，本申请对材料并不做限定，具体视实际情况而定。例如，本申请中的第一紫外光吸收层和第二紫外光吸收层中掺杂有吸光胶囊水杨酸脂类化合物和苯并三唑类化合物及丙烯腈类化合物三种物质。
本实施例中，第二柔性衬底102包括显示区和非显示区，第二柔性衬底102背离第一柔性衬底101的一侧的所属于显示区表面设置有第二紫外光吸收层。
一般来说，当在显示面板上的第二柔性基板上制备第二紫外光吸收层，能够有效的降低激光剥离刚性衬底过程中紫外光通过柔性衬底的透射率，以保护柔性衬底和内部器件不受紫外光的影响，提高了产品的良率。
为了更好实施本发明实施例中显示面板，在显示面板的基础之上，本发明实施例中还提供一种显示面板的制作方法，如图2所示，方法包括：
