Display device with current compensation and manufacturing method thereof

A display device, comprising:

• a display area and a non-display area surrounding the display area, wherein the display area includes a substrate, a first insulating layer, a first gate layer, a second insulating layer, and a second gate layer;
• wherein the non-display area includes an integrated circuit area, and a thickness of the second insulating layer gradually decreases from a vicinity of the integrated circuit area toward a direction away from the integrated circuit area;
• wherein the display area is divided into N-numbered sub-display areas arranged side by side, and the N-numbered sub-display areas are arranged in order from the vicinity of the integrated circuit area toward the direction away from the integrated circuit area;
• a thickness of the second insulating layer located at the (X+1)-numbered sub-display area is less than a thickness of the second insulating layer located at the X-numbered sub-display area;
• and/or
• a capacitance of the (X+1)-numbered sub-display area is larger than a capacitance of the X-numbered sub-display area, wherein N≥X≥2.
