DISPLAY PANEL AND MANUFACTURING METHOD THEREOF

A display device including a plurality of sub-pixels is provided. The sub-pixels are disposed on a substrate. Each of the sub-pixels has an active element, a first electrode, a first bank layer, a second bank layer, an emissive layer and a second electrode. The first bank layer is disposed on the first electrode and has a first hole overlapping a portion of the first electrode. The second bank layer is disposed on the first bank layer and has a second hole overlapping the first hole. The first bank layer has a material region. A normal projection of the material region on the substrate is located between a normal projection of the first hole on the substrate and a normal projection of the second hole on the substrate. The material region has a first width in a first direction. The material region has a second width in a second direction interlaced with the first direction. A first width of a material region of a first sub-pixel of the sub-pixels is not equal to a second width of the material region of the fir
