随着科技的发展和进步，液晶显示器由于具备机身薄、省电和辐射低等热点而成为显示器的主流产品，得到了广泛应用。市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶面板及背光模组(backlightmodule)。液晶面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
液晶面板在彩膜基板(Color Filter，CF)制程中，在CF上制备间隙子(Photo Spacer，PS)用以在CF基板和薄膜晶体管(Thin Film Transistor，TFT)基板对盒后支撑两者之间的间隙，两者之间的间隙高度叫做盒厚(Cell Gap)。PS是用单独的光罩进行曝光显影制成，不仅耗费时间，而且光罩成本高。

可选的，第二间隙子的第一间隙子基层的长度大于第二间隙子基层的长度。
可选的，第二间隙子的第二间隙子基层的中部凸出于两侧，且中部分别与两侧成台阶结构，所述第二间隙子的第一色间隙子的长度等于所述第二间隙子基层的中部长度。
可选的，所述第三间隙子包括第二间隙子基层，形成第二色滤光片时，可同时形成第二间隙子基层。
可选的，所述显示面板还包括黑矩阵，所述黑矩阵设置在第一基板上；所述第一间隙子和第二间隙子分别形成在黑矩阵上。
本申请公开了一种显示面板，所述显示面板包括第一基板，设置在第一基板上的第一色滤光片、第二色滤光片、第三色滤光片，及形成有段差的第一间隙子、第二间隙子和第三间隙子；其中，所述的第一间隙子包括堆叠的第一间隙子基层、第二间隙子基层和第三间隙子基层；所述第一间隙子的第三间隙子基层的中部凸出两侧且中部分别与两侧成台阶结构，所述第一间隙子的第一间隙子基层的长度等于所述第一间隙子的第二间隙子基层的长度，所述第一间隙子的第一间隙子基层的长度小于所述第一间隙子的第三间隙子基层的中部的长度；所述的第二间隙子包括堆叠的第一间隙子基层和第二间隙子基层；所述第二间隙子的第一间隙子基层的长度大于第二间隙子基层的长度；所述的第三间隙子包括第二间隙子基层；其中，所述第一色滤光片和所述第一间隙子基层同层形成；所述第二色滤光片和所述第二间隙子基层同层形成；所述第三色滤光片和所述第三间隙子基层同层形成；所述显示面板还包括黑矩阵，所述黑矩阵设置在第一基板上；所述第一间隙子、第二间隙子和第三间隙子分别形成在黑矩阵上。

下面结合附图和可选的实施例对本申请作进一步说明。
参考图1、图2和图3；液晶面板在CF制程中，在CF基板上制备间隙子(Photo Spacer，PS)用以在CF基板和TFT基板对盒后支撑两者之间的间隙，两者之间的间隙高度叫做盒厚(Cell Gap)，在液晶盒中填充液晶才形成液晶面板。在液晶面板成产中，会形成子间隙子(Sub PS)，在正常情况下，Sub PS悬空，直接由主间隙子(Main PS)起支撑作用，在面板受压情况下，Sub PS会起支撑作用，这样可以保证面板在受压时也能有支撑。液晶盒是存在一定弹性的，这样装在液晶盒的液晶会有一个较大范围的上下限，太多会存在重力不均匀(Mura)，太少会出现气泡(Bubble)，也就是所谓的LC Margin。一般情况下PS断差较大的LC Margin较大，对生产来说可以提高生产良率，提高产品品质。PS设计时，Main PS和Sub PS一般使用半色调掩膜(Half Tone Mask，HTM)或者灰色光罩(Gray Tone Mask，GTM)在CF侧将PS做出断差，但是HTM/GTM Mask的价格较贵使得生产成本较高，且断差高端不好控制。
显示面板101以液晶显示面板101为例，参考图4所示，本申请一实施例公开了一种显示面板101，包括第一基板110，设置在第一基板110上的第一色滤光片120、第二色滤光片130、第三色滤光片140，及形成有段差的第一间隙子150和第二间隙子160；
其中，第一间隙子150包括堆叠的第一间隙子基层180和第二间隙子基层190；第二间隙子160包括第一间隙子基层180；
其中，第一色滤光片120和第一间隙子基层180同层形成；第二色滤光片130和第二间隙子基层190同层形成。
显示面板101在第一基板110的制程中，需要在第一基板110上制备间隙子(Photo Spacer)用以在第一基板110和第二基板对盒后支撑两者之间的间隙，两者之间的间隙 高度叫做Cell Gap(盒厚)。第一基板110要先形成第一色滤光片120、第二色滤光片130、第三色滤光片140，之后再形成间隙子。间隙子是用单独的光罩进行曝光显影制成，不仅耗费时间，而且光罩成本高。本方案中，第一色滤光片120和第一间隙子基层180通过同一道光罩同层形成；第二色滤光片130和第二间隙子基层190通过同一道光罩同层形成，不用额外单独的间隙子制程，节省时间，间隙子的形成不要再用单独的光罩进行曝光显影制成，节省一道光罩，降低生产成本。
在一实施例中，第一间隙子150还包括与第一间隙子基层180和第二间隙子基层190堆叠的第三间隙子基层200；第三色滤光片140和第三间隙子基层200同层形成；第二间隙子160还包括与第一间隙子基层180堆叠的第二间隙子基层190。
本方案中，第一间隙子150还包括第三间隙子基层200，第一间隙子基层180、第二间隙子160基层和第三间隙子基层200堆叠，液晶盒的盒厚是有最低要求的，而第一色滤光片120、第二色滤光片130以及第三色滤光片140的膜厚较薄，将第一间隙子150设置成堆叠的三层，可以更容易使第一间隙子150的厚度达到液晶盒盒厚的最低要求，若只有两层，要增加滤光片的膜厚，对透光率有影响。
在一实施例中，显示面板101还包括第三间隙子170，第三间隙子170包括第一间隙子基层180；第三间隙子170与第一间隙子150、第二间隙子160分别形成有段差。
本方案中，显示面板101还包括第三间隙子170，第三间隙子170与第一间隙子150、第二间隙子160分别形成有两个段差，将堆叠的第一间隙子基层180、第二间隙子基层190和第三间隙子基层200为第一间隙子150，将堆叠的第一间隙子基层180和第二间隙子基层190作为第二间隙子160，这样，面板在对盒后，第一间隙子150形成支撑盒厚，第二间隙子160和第三间隙子170都悬空，当显示面板101受到较小的压力时，第一间隙子起作用，当显示面板101受到稍大的压力时，第二间隙子160起作用，当显示面板101受到更大的压力时，第三间隙子170起作用，这样显示面板101的弹性范围更好，能容纳液晶量的上下限较大，能提升产品的液晶裕度(LC Margin)，提高生产良率，提高产品品质。第一间隙子150和第二间隙子160形成一个段差，将堆叠的第一间隙子基层180、第二间隙子基层190为第一支撑物，将第一间隙子基层180作为第二支撑物，这样，面板在对盒后，第一支撑物形成盒厚，第二支撑物悬空，当面板受压时，第二支撑物才起作用，液晶盒是存在一定弹性的，这样装在液晶盒的液晶会有一个较大范围的上下限，能提升产品的液晶裕度(LC Margin)，提高生产良率，提高产品品质。
在一实施例中，第一间隙子150的第三间隙子基层200的中部凸出两侧且中部分别与两侧成台阶结构，第一间隙子150的第一间隙子基层180的长度等于第一间隙子150的第二间隙子基层190的长度，第一间隙子150的第一间隙子基层180的长度小于第一 间隙子150的第三间隙子基层200的中部的长度。
在一实施例中，第二间隙子160的第一间隙子基层180的长度大于第二间隙子基层190的长度。
本方案中，第二间隙子160的第一间隙子基层180的长度大于第二间隙子基层190的长度，相对于设置第一间隙子基层180的长度与第二间隙子基层190的长度相等的情况，扩大了可容纳液晶量的空间，保证产品良率。
在一实施例中，第二间隙子160的第二间隙子基层190的中部凸出于两侧，且中部分别与两侧成台阶结构，第二间隙子160的第一色间隙子的长度等于第二间隙子160基层的中部长度。
本方案中，第二间隙子160的第二间隙子基层190的中部分别与两侧成台阶结构，第二间隙子基层的中部可在正常状况下维持显示面板101的液晶盒间隙，与第二间隙子基层的中部形成台阶状的两侧则可在受外力按压状况下限制受压距离，借此增加显示面板101的耐压性。
在一实施例中，第三间隙子170包括第二间隙子基层190，形成第二色滤光片130时，可同时形成第二间隙子基层190。
在形成第二色滤光片130时，可同时形成第二间隙子基层190，节省制程。
在一实施例中，显示面板101还包括黑矩阵201，黑矩阵201设置在第一基板110上；
第一间隙子150和第二间隙子160分别形成在黑矩阵201上。
本方案中，第一间隙子150和第二间隙子160分别形成在黑矩阵201上，可以更好的遮光。
作为本申请一实施例，参考图4至图7所示，公开了一种显示面板101，包括第一基板110，设置在第一基板110上的第一色滤光片120、第二色滤光片130、第三色滤光片140，及形成有段差的第一间隙子150、第二间隙子160和第三间隙子170；
其中，所述第一间隙子150包括堆叠的第一间隙子基层180、第二间隙子基层190和第三间隙子基层200；
第一间隙子150的第三间隙子基层200的中部凸出两侧且中部分别与两侧成台阶结构，第一间隙子150的第一间隙子基层180的长度等于第一间隙子150的第二间隙子基层190的长度，第一间隙子150的第一间隙子基层180的长度小于第一间隙子150的第三间隙子基层200的中部的长度；
所述第二间隙子160包括堆叠的第一间隙子基层180和第二间隙子基层190；
第二间隙子160的第一间隙子基层180的长度大于第二间隙子基层190的长度；
所述第三间隙子170包括第二间隙子基层190；
其中，第一色滤光片120和第一间隙子基层180同层形成；第二色滤光片130和第二间隙子基层190同层形成；第三色滤光片140和第三间隙子基层200同层形成；
显示面板101还包括黑矩阵201，黑矩阵201设置在第一基板110上；
