Description

一种显示面板及其制作方法 【技术领域】
本申请涉及一种显示面板技术领域，特别是涉及一种降低电路阻容负载的显示面板及其制作方法。
【背景技术】
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。现有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(back light module)。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。
其中，薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能，目前已经逐渐占据了显示领域的主导地位。同样，薄膜晶体管液晶显示器包含液晶面板和背光模组，液晶面板包括第二基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)、薄膜晶体管第一基板(Thin Film Transistor Substrate，TFT Substrate)和光罩(Mask)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。
而薄膜晶体管层液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)为了凸显出现实画面的一体感，窄边框和无边框逐渐成为液晶显示器重要的发展方向，而在实现窄边框和无边框的时候，能够减少生成成本，则更是本领域技术人员的追求；
顺应这种发展趋势，GOA(Gate Driver on Array，即栅阵列电路)电路得到了广泛应用。GOA电路采用与面内液晶驱动开关等半导体器件相同的成膜方式来与第一基板面内结构同时制作，它的出现省去了扫描线驱动芯片的成本，同时 无需焊接柔性电路板FPC到液晶显示面板的边缘。GOA电路不仅使得液晶显示器的控制和设计更加方便，也大大降低了液晶显示器边框的宽度。
但GOA技术也存在着一些暂时无法很好解决的问题，例如，相关电路阻容负载过大的问题。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
【发明内容】
有鉴于现有技术的上述缺陷，本申请所要解决的技术问题是提供能够减缓和降低电路阻容负载的显示面板及其制作方法
为实现上述目的，本申请提供了一种降低电路阻容负载的显示面板及其制作方法，该显示面板包括：
第一基板；
第二基板，包括色阻层，与所述第一基板相对设置；
设置在所述第一基板和第二基板之间的液晶层；
其中，所述第一基板包括电路区，以及显示区；
所述电路区上形成有一间隔层，所述间隔层的介电常数低于所述液晶层的介电常数；
所述电路区包括：
驱动区，集成有栅极驱动芯片；以及
引线区，将驱动区的信号传递给所述显示区内的扫描线；
所述间隔层分别对应所述驱动区和引线区设置在所述第一基板和第二基板之间；
所述间隔层包括聚苯乙烯材料。
本申请还公开了一种显示面板的制作方法，包括步骤：
形成第一基板；
形成第二基板，与第一基板相对设置；
在所述第二基板上形成色阻层；
在所述第一基板以及第二基板之间形成液晶层；
在所述第一基板的显示区的外围曝光显影，形成电路区；
在所述第一基板和第二基板之间，对应电路区设置间隔层，所述间隔层的介电常数低于液晶层。
本申请中，由于，在第一基板和第二基板之间，对应电路区的部分设置有介电常数低于液晶层的间隔层，根据平行電容公式得知C＝εA/d，以及间隔层的介电常数低于液晶的特性，可知，如是设置之后，电路区处的整体电容，将能够得到有效的降低，进而得以缓解阻容负载过大的问题。
