Abstract: A detection panel and a manufacturing method thereof are disclosed. The detection panel (200) includes a first substrate (21) and a second substrate (22), and the first substrate (21) includes a light detection layer (213); the second substrate (22) includes a drive circuit (205); the first substrate (21) and the second substrate (22) are opposite to each other for cell assembly, and the drive circuit (205) is coupled to the light detection layer (213) to read a photosensitive signal generated by the light detection layer (213). By forming the light detection layer (213) and the drive circuit (205) on different substrates, the detection panel (200) contributes to increase the flatness of the light detection layer (213) and reduce the defects of the light detection layer (213), thereby reducing the leakage current in a dark state and improving the performance of the detection panel (200).
