Abstract
The disclosure provides a display panel and a manufacturing method thereof. The method includes: forming a main gate and a sub-gate on a glass substrate, wherein at least a portion of the sub-gate includes a light transmissive area; sequentially forming a gate insulating layer, a semiconductor layer, and a second metal layer on the sub-gate, patterning the semiconductor layer to obtain a main active layer and a sub-active layer, and patterning the second metal layer to obtain a main source/drain and a sub-source/drain.
