透明光传导层33背离基板1的一侧且与每个子像素32相对的位置形成有多个突起34。
通过在透明光传导层33背离每个子像素32的一侧设置突起34，可以进一步强化透明光传导层33的导光效果，使每个像素单元3发出的光线更为均匀。
具体地，每个突起34沿垂直于基板1方向的截面中，背离基板1的一侧的轮廓线的形状可以为折线形、半圆形、抛物线形中的一种，或者为其它的不规则形状，只需满足可进一步将光线均匀化即可，具体形状本申请不作限定。
具体地，突起34可以通过刻蚀或显影的方式制备，本申请不作限定。
透明光传输部31和透明光传导层33均采用可透光且可混色的材质制备而成。
透明光传输部31和透明光传导层33的材质相同，从而可以避免光线在透明光传输部31和透明光传导层33之间发生折射，以保证显示效果；透明光传输部31和透明光传导层33的材质可以选用透明的聚酰亚胺，透明的聚酰亚胺材料的混光和透光的效果好，且材料简单易得。
遮挡层4与透明光传导层33同层设置。
将遮挡层4与透明光传导层33同层设置，可以不占用像素单元3之间的空间，从而保证透明显示面板的分辨率，同时将遮挡层4仅设置为与透明光传导层33同层，可在满足挡光效果的同时减小遮挡层4的厚度，从而节省遮挡层4的材料，且达到良好的防混光效果。
遮挡层4为黑色色组矩阵。
采用黑色色组矩阵可防止相邻像素单元3发生混色，特别是防止相邻像素单元3的相邻子像素32之间发生混色，通过黑色色组矩阵将相邻的像素单元3发出的光线隔离，可使得每个像素单元3发光彼此独立，互不干扰，从而使得整个透光显示面板的显示效果更好。
本申请还提供了一种上述透光显示面板的制备方法，如图3所示，包括：
S101，在基板1上形成多个像素单元3，各像素单元3包括透明光传输部31和围绕透明光传输部31分布的至少三种颜色的子像素32；
S102，在相邻像素单元3之间形成遮挡层4，遮挡层4包括与每个像素单元3一一对应的开口，像素单元3位于开口内。
上述制备方法中，首先制备像素单元3，然后再制备遮挡层4，遮挡层4位于相邻像素单元3之间，从而使得相邻的像素单元3隔离，避免发生混光；每个像素单元3包括透明光传输部31和至少三种颜色的子像素32，各个子像素32围绕透明光传输部31分布，从而可使各个子像素32发出的光线在透明光传输部31内充分混光，从而将每个子像素32的点光源变成整个像素单元3的面光源，提升显示效果，且透明光传输部31可以透光，从而可增大用户在驾驶过程中的视觉范围，使得该透明显示面板在应用于车载设备时不遮挡用户的视线，从而提升驾驶安全性。
如图4所示，在上述制备透光显示面板的制备方法中，步骤S101包括：
S1011，在基板1上的每个用于形成透明光传输部31的透光区域周围形成至少三种颜色的子像素32；
S1012，沉积可透光且可混色的材质以在用于形成透明光传输部31的透光区域内形成透明光传输部31，并在子像素32背离基板1的一侧形成透明光传导层33。
将透明光传输部31和透明光传导层33采用同一种材料且同一次工艺制备形成，可避免光线依次穿过透明光传输部31和透明光传导层33时在透明光传输部31和透明光传导层33的交界处发生折射，从而保证视觉效果，同时将透明光传输部31和透明光传导层33采用一次工艺制备形成可简化制作工艺，从而节省制备时间。透光区域可包括设置于基板1上的透明层，透明光传输部31可设置于透明层上，其中，透明层可包括阻挡层、绝缘层以及平坦层等膜层。
本申请的透光显示面板的制备方法还包括：在透明光传导层33背离基板1的一侧且与每个子像素相对的位置形成多个突起34。所述突起34通过刻蚀或显影的方式形成。
本申请还提供了一种显示装置，所述显示装置包括上述透光显示面板。
该显示装置可用于需内置车载显示装置的交通工具中，该显示装置可视度强、亮度适中，同时保证了用户的视觉范围，实现了显示效果与用户的视觉范围的兼得，从 而可在保证显示装置视觉效果的同时，避免遮挡用户的视线，从而提升驾驶安全性；该显示装置不限于应用于交通工具，也可根据实际的需求应用于其它场合，本申请不作限定。
以上，仅为本申请的具体实施方式，所属领域的技术人员可以清楚地了解到，本领域的技术人员可以对本申请实施例进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
