可选地，所述第一信号走线311和所述第二信号走线321的表面形状包括矩形等，把所述第一信号走线311和所述第二信号走线321的表面形状设置为矩形等规则的形状可以降低工艺难度。
可选地，所述第一信号走线311和所述第二信号走线321的截面形状包括矩形、梯形等，如图1示出的截面形状为矩形。
可选地，请参照图5，当所述第一信号走线311和所述第二信号走线321的截面形状为梯形时，梯形的侧边3214也会反射外界环境光，故梯形的底角b越小，反射率越低。
可选地，所述第二信号走线321的宽度L1等于所述第一信号走线311的宽度L2，当然地，本申请不限于此，本申请的所述第二信号走线321的宽度L1也可以不等于所述第一信号走线311的宽度L2。
进一步地，所述第一信号走线311在所述基板10上的正投影与所述第二信号走线321在所述基板10上的正投影重合，如此所述第二信号走线321对所述第一信号走线311的遮蔽效果更好。
可选地，所述第二信号走线321的数量大于或等于所述第一信号走线311的数量。当所述第二信号走线321的数量大于所述第一信号走线311的数量时，所述第一信号走线311与部分的所述第二信号走线321对应设置；当所述第二信号走线321的数量等于所述第一信号走线311的数量时，所述第一信号走线311与所述第二信号走线321对应设置，如图4示出的，所述第一信号走线311的数量与所述第二信号走线321的数量相等，且两者在所述基板10的正投影重合。
可选地，所述第一信号走线311和所述第二信号走线321均可以为数据信号走线和/或电源线，且所述第一信号走线311和所述第二信号走线321其中之一为所述数据信号走线，另一个为所述电源线。
通过把所述第一信号走线311和所述第二信号走线321均沿第二方位角的方向设置，且所述第二信号走线321与所述第一信号走线311在所述基板10上的正投影重合，使所述第二信号走线321在不同的方位角下遮蔽第一信号走线311的面积不同，形成不同的金属反射面积，以使得显示面板本体1在第一方位角上的金属反射面积大于第二方位角上的金属反射面积，以补偿偏光片2在第二方位角上的消光性。
下面将具体描述使显示面板本体1在第一方位角上的金属反射面积大于第二方位角上的金属反射面积的实现原理：
请参照图6，图6为本申请实施例提供的第一信号走线和第二信号走线的空间位置关系示意图。在图6中，以所述显示面板本体在180度的方位角上的金属反射面积与在270度的方位角上的金属反射面积对比为例说明。
在180度的方位角上，外界环境光以与第一信号走线311和第二信号走线321呈预设夹角a射向第一信号走线311和第二信号走线321，由于第二信号走线321遮蔽部分所述第一信号走线311，使被第二信号走线321遮蔽的第一信号走线311部分不会被外界环境光照射，故在180度方位角上的金属反射面积包括第二信号走线的表面及未被所述第二信号走线遮挡的第一信号走线的面积。
在270度的方位角上，外界环境光仍以与第一信号走线311和第二信号走线321呈预设夹角a射向第一信号走线311和第二信号走线321，由于第二信号走线321遮蔽部分所述第一信号走线311，使被第二信号走线321遮蔽的第一信号走线311部分不会被外界环境光照射，故在270度方位角上的金属反射面积包括第二信号走线的表面及未被所述第二信号走线遮挡的第一信号走线的面积。
由于第一信号走线311和第二信号走线321均沿第二方位角的方向间隔排布，也即沿竖直方向间隔排布，故在270度的方位角上，未被第二信号走线321遮挡的第一信号走线311的面积小于180度方位角上未被第二信号走线321遮挡的第一信号走线311的面积。同样地，在0度方位角上第二信号走线321的遮挡效果和在180度方位角上相同，在90度方位角上第二信号走线321的遮挡效果和在270度方位角上相同。故显示面板本体1在第一方位角上的金属反射面积大于第二方位角上的金属反射面积。
需要说明的是，本申请中的“同层设置”是指在制备工艺中，将相同材料形成的膜层进行图案化处理得到至少两个不同的特征，则所述至少两个不同的特征同层设置。比如，本实施例的第二信号走线321与第二源极322由同一导电膜层进行图案化处理后得到，则第二信号走线321与第二源极322同层设置。
所述平坦化层14覆于所述第二源漏极层32以及所述第二层间绝缘层13上，所述发光功能层50设置于所述平坦化层14上。所述发光功能层50包括像素电极51、像素定义层52、发光材料层53、阴极层54。所述像素电极51通过所述平坦化层14的过孔与所述第二源极322连接，所述像素定义层52覆于所述像素电极51以及所述平坦化层14上，且所述像素定义层52图案化形成有像素开口，所述像素开口裸露出部分所述像素电极51，以定义出发光材料的设置区域。所述发光材料层53是由打印在所述像素定义层52的像素开口内的发光材料形成，所述阴极层54覆盖所述发光材料层53以及所述像素定义层52。所述发光材料层53在所述像素电极51和所述阴极层54的共同作用下发光，进而实现显示面板本体1的像素显示。
所述像素电极51可以是透明电极或反射电极。如果所述像素电极51是透明电极，则所述像素电极51可以由例如氧化铟锡(ITO)、氧化铟锌(IZO)、ZnO或In2O3 形成。如果所述像素电极51是反射电极，则所述像素电极51例如可以包括由Ag、 Mg、Al、Pt、Pd、Au、Ni、Nd、Ir、Cr或它们的组合形成的反射层以及由 ITO、IZO、ZnO或In2O3 形成的层。然而，像素电极51不限于此，像素电极51可以由各种材料形成，并且也可以形成为单层或多层结构。
所述阴极层54采用透明导电材料形成，以提高所述发光材料层53的光的透过率，例如所述阴极层54可以由逸出功低的金属(如Li、Ca、LiF/Ca、LiF/Al、 Al、Ag、Mg或它们的组合)形成的层以及由ITO、IZO、ZnO或In2O3形成的透明导电层。所述像素电极51为反射电极时，可进一步提高所述发光材料层53的光的利用率。
当然的，所述发光功能层50还可包括设置于所述发光材料层53与所述像素电极51之间的空穴注入层(HIL)、空穴传输层(HTL)；以及设置于所述发光材料层53与所述阴极层54之间的电子注入层(EIL)、电子传输层(ETL)。
所述显示面板本体1还可包括设置于所述发光功能层50上的封装层60，所述封装层60可以采用薄膜封装，所述薄膜封装可以为由第一无机封装层、有机封装层、第二无机封装层三层薄膜依次层叠形成的叠层结构或更多层的叠层结构，用于保护所述发光功能层50的发光材料层53，避免水氧入侵导致发光材料层53失效。
可选地，本申请的显示面板100还可包括设置于所述偏光片2与所述显示面板本体1之间的触控功能层（图未示），所述触控功能层直接设置在所述封装层60上，采用DOT触控方案，以实现触控功能。当然的，本申请不限于此，本申请的显示面板100也可以采用外挂式触控方案。
