Substrate and display panel

A display panel, comprising:

• a first base substrate and a substrate disposed on the first base substrate;
• wherein the substrate comprises:
• a base substrate;
• and
• a plurality of sub-pixel structures arranged in an array on the base substrate,
• wherein each of the plurality of sub-pixel structure comprises:
• a thin film transistor disposed on the base substrate, the thin film transistor comprising a source and a drain;
• an insulating layer disposed on a side of the thin film transistor distal from the base substrate, a first via hole being formed in the insulating layer;
• a pixel electrode disposed on a side of the insulating layer distal from the base substrate, the pixel electrode being electrically connected to either the source or the drain through the first via hole;
• and
• a light shielding pattern disposed on a side, proximal to the base substrate, of the source and the drain, wherein the light shielding pattern comprises a plurality of light shielding portions and a plurality of connecting portions;
• wherein the plurality of light shielding portions is connected to the plurality of connecting portions, each of the plurality of light shielding portions is extended along a first direction, and the plurality of light shielding portions are arranged along a second direction;
• and the plurality of connecting portions are disposed on two sides of the light shielding portion in the second direction, each of the plurality of connecting portions is extended along the second direction, and the plurality of connecting portions are arranged along the first direction;
• wherein the second direction intersects the first direction.
