Display substrate and manufacturing method thereof

A manufacturing method of a display panel, comprising:

• providing a base plate;
• forming a driving circuit on one side of the base plate;
• forming a first insulation layer on the driving circuit such that the first insulation layer covers the driving circuit;
• patterning the first insulation layer to form through holes, such that parts of the driving circuit are exposed through the through holes;
• forming signal conductor lines on a surface of the first insulation layer such that the signal conductor lines are electrically connected, via the through holes, to the driving circuit;
• and
• arranging pixel units on a surface of the signal conductor lines, such that the pixel units are electrically connected with the signal conductor lines;
• wherein each of the pixel units comprises a plurality of sub pixel units of different colors, the driving circuit being arranged between two adjacent rows of the pixel units, the driving circuit comprising a plurality of sub driving circuits, each of the sub pixels being connected through one of the signal conductor lines with the sub driving circuits, the sub driving circuits transmitting an image driving signal through the signal conductor lines to the sub pixel units for driving the sub pixel units to display an image, and
• wherein the plurality of sub driving circuits of the driving circuit are arranged in sequence to form a row, the row of the sub driving circuits being located between and spaced from the two adjacent rows of the pixel units between which the at least one driving circuit is arranged.
