需要说明的是，在一种实施例中，如图1所示，散光构件133由衬底基板132形成，即散光构件为第一基板的一部分，图1中第一基板13包括衬底基板132和公共电路层131，但第一基板不限于此。
需要说明的是，透过角度为光线透出第一基板后与第一基板的夹角，取直角或者钝角。
在一种实施例中，如图1所示，所述显示面板为液晶显示面板，在对盒设置的第一基板13和第二基板11之间的对盒空间设有液晶12，所述第一基板13包括公共电极层131和衬底基板132，所述衬底基板132的上表面形成散光构件133，所述光线14透过所述散光构件133进行散射，通过在衬底基板上形成散光构件，使得光线透过第二基板、液晶和第一基板后以发散的角度透出，从而增大了显示面板的透过角度，提高了显示面板的可视角度。

在一种实施例中，如图2所示，所述第一基板为彩膜基板，所述第二基板21为阵列基板，所述彩膜基板设置于所述阵列基板的出光方向上，在所述阵列基板与所述彩膜基板之间设有液晶22，所述彩膜基板包括衬底基板234、黑色矩阵层232、光阻层233和公共电极层231，所述衬底基板234的一侧表面形成有散光构件235；通过在衬底基板上形成散光构件，使得光在透过阵列基板、液晶和彩膜基板后以散射透过，提高了光的透过角度，从而提高了显示面板的可视角度，解决了现有显示面板存在可视角度较小的技术问题。
在一种实施例中，如图2所示，所述衬底基板234远离所述阵列基板21的一侧表面形成有散光构件235，即在衬底基板远离所述阵列基板的一侧形成散光构件，使得光线进入衬底基板靠近阵列基板的一侧表面后，再经过衬底基板远离阵列基板的一侧表面散射透出，进而提高显示面板的可视角度。

在本申请实施例中，考虑到在衬底基板靠近阵列基板的一侧表面形成有散光构件时，衬底基板与光阻层接触的表面，以及衬底基板与黑色矩阵层接触的表面不平整，如图3所示，通过将黑色矩阵层和光阻层设计为与散光构件相对应的曲面，使得衬底基板与光阻层接触的表面，以及衬底基板与黑色矩阵层接触的表面贴合平整，从而使得彩膜基板变得平整。
在一种实施例中，所述彩膜基板设置于所述阵列基板的出光方向上，所述彩膜基板包括衬底基板，可在所述衬底基板靠近阵列基板的一侧表面形成第一散光构件，在所述衬底基板远离所述阵列基板的一侧表面形成有第二散光构件，通过在衬底基板的靠近阵列基板的一侧表面和远离阵列基板的一侧表面分别设置第一散光构件和第二散光构件，使得光在透过光阻层后先经过第一散光构件进行第一次散射，然后在通过第二散光构件时进行第二次散射，使得光经过了两次散射，提高了光的透过角度，使得显示面板的可视角度进一步提高。
在一种实施例中，第一散光构件与第二散光构件相同，即在衬底基板靠近阵列基板的一侧表面和衬底基板远离阵列基板的一侧表面形成相同的散光构件，使得光线在经过两次散射后以更大的透过角度透出，提高了显示面板的可视角度。
在一种实施例中，第一散光构件与第二散光构件不同，例如第一散光构件为图3中的散光构件，第二散光构件根据第一散光构件进行相对应的设计，使得光线在经过第一散光构件散射后，在经过第二散光构件散射能得到更大的透过角度，进而进一步提升显示面板的可视角度。
在一种实施例中，第一散光构件与第二散光构件不同，第二散光构件根据第一散光构件进行相对应的设计，考虑到光线在经过第一散射构件进行散射后，会存在部分光线无法透出，将第二散光构件根据第一散光构件进行相对应的设计，使得在使光线以更大的角度散射出去，同时保证光线能够透出去，防止部分光线损失，使得显示面板的光强不变的同时，提高显示面板的可视角度。
在一种实施例中，如图1、图2、图3所示，所述散光构件包括一个凹面，通过将衬底基板的表面设计为凹面，使得其能够达到散光的效果，进而提高显示面板的可视角度。

在一种实施例中，针对光线通过光阻层透出，而在黑色矩阵对应区域，没有光线透出，如图4所示，在对应光阻层的区域形成凹面，进而形成散光构件，使得光线在经过光阻层后进入衬底基板靠近阵列基板的一侧发生散射，从而提高光的透过角度，提高显示面板的可视角度。
在一种实施例中，第一散光构件设置于对应光阻层的区域，所述第一散光构件包括多个凹面，在光线透过光阻层进入衬底基板时，第一散光构件将光线进行发散，第二散光构件包括一个整面形成的凹面，在光线经过衬底基板靠近阵列基板的一侧表面后，第二散光构件将光线再次进行散射，通过一个整面的凹面使得光线在进入衬底基板远离阵列基板的一侧表面后，进行第二次散射，提高了显示面板的可视角度。
如图5所示，本申请实施例提供一种显示面板，该显示面板包括第一显示区51和第二显示区52，所述第一显示区51围绕所述第二显示区52设置，在所述第一显示区内设置有散光构件，考虑到在显示面板中间区域设置散光构件能将光线散射，例如将散光构件设置于第二显示区，但会出现光散射角度不大，通过将散光构件设置在第一显示区，使得光线的散射角度增大，从而提高了显示面板的可视角度。
在一种实施例中，在衬底基板靠近阵列基板的一侧表面形成第一散光构件，所述第一散光构件设置于第二显示区，在衬底基板远离阵列基板的一侧表面形成第二散光构件，所述第二散光构件设置于第一显示区，通过将第一散光构件设置于第二显示区，将第二散光构件设置于第一显示区，使得通过第二显示区的光通过第一散光构件散射出显示面板和第二散光构件上，通过第一散射构件散射到第二散光构件的光再次散射透出，通过第一显示区的光通过第二散光构件散射出显示面板；使得光线不会通过第一散光构件后无法透出，而通过第一散光构件的光散射到第二散光构件的光能再次发散透出，保证了光的强度不改变，提高了光的透过角度，提高了显示面板的可视角度。
在一种实施例中，可在彩膜基板上方形成散光构件，即使散光构件在彩膜基板远离阵列基板的一侧表面凸起，但散光构件可散光，使得通过彩膜基板的光通过散光构件进行发散，提高了显示面板的可视角度。
在本申请实施例中，由于衬底基板与偏光片之间设有光学胶，在衬底基板远离第二基板的一侧表面形成散光构件时，可使用光学胶填充空隙，从而使得衬底基板与偏光片接触的表面平整，进而使得显示面板平整。
需要说明的是，上述实施例中衬底基板位于彩膜基板上，彩膜基板设置于阵列基板的出光方向上，下述实施例中衬底基板位于阵列基板上，阵列基板设置于彩膜基板的出光方向上。

在一种实施例中，阵列基板设置于彩膜基板的出光方向上，在阵列基板的衬底基板靠近彩膜基板的一侧形成有散光构件，即在衬底基板中与缓冲层接触的表面形成散光构件，使得光线在透过缓冲层透过衬底基板靠近彩膜基板的一侧表面时发生散射，然后透过衬底基板远离彩膜基板的一侧表面散射透过，提高了光线的透过角度，增大了显示面板的可视角度。
在一种实施例中，考虑到在衬底基板靠近彩膜基板的一侧表面形成散光构件会造成衬底基板与缓冲层接触的表面不平整，可将缓冲层增大，使得缓冲层与衬底基板接触的表面设计为互补，从而使得阵列基板平整，进而使得显示面板平整。
在一种实施例中，在衬底基板靠近彩膜基板的一侧表面形成第三散光构件，在衬底基板远离彩膜基板的一侧表面形成第四散光构件，通过在衬底基板靠近彩膜基板的一侧表面形成第三散光构件、在衬底基板远离彩膜基板的一侧表面形成第四散光构件，使得光经过两次散光后以更大的角度透出，提高了光的透过角度，从而提高了显示面板的可视角度。
在一种实施例中，第三散光构件与第四散光构件相同，即在衬底基板靠近彩膜基板的一侧表面和衬底基板远离彩膜基板的一侧表面形成相同的散光构件，使得光线在经过两次散射后以更大的透过角度透出，提高了显示面板的可视角度。
