Display panel and display device

A display panel, comprising:

• a substrate;
• active switches disposed on the substrate;
• a color filter layer disposed on the substrate;
• a passivation layer disposed on the substrate, wherein the passivation layer covers the substrate, the active switches, and the color filter layer;
• a buffer layer disposed to cover the substrate,
• an interlayer dielectric layer disposed between the buffer layer and the passivation layer, wherein the color filter layer is disposed on the interlayer dielectric layer and the color filter layer is disposed separately from the active switches;
• wherein the active switch comprises a semiconductor layer, a source electrode, and a drain electrode;
• the source electrode and the drain electrode respectively connect two ends of the semiconductor layer and the semiconductor layer is disposed between the buffer layer and the interlayer dielectric layer, and one end of each one of the source electrode and the drain electrode is disposed between the passivation layer and the interlayer dielectric layer, and the other end of each one of the source electrode and the drain electrode extends through the interlayer dielectric layer and connects the semiconductor layer;
• and
• a light shading layer disposed on the substrate and between the buffer layer and the substrate, wherein the source electrode extends through the buffer layer and connects the light shading layer, and the light shading layer is disposed between orthographic projecting positions of the source electrode and the drain electrode on the substrate, and the light shading layer fills an interval between the orthographic projecting positions of the source electrode and the drain electrode on the substrate.
