Abstract

The present disclosure provides an array substrate and a display panel including the same. The array substrate includes a plurality of pixel units. Each of the pixel units includes a main pixel electrode, a sub-pixel electrode, a first thin film transistor (TFT) electrically connected to the sub-pixel electrode, a second TFT electrically connected to the first TFT, and a third TFT electrically connected to the main pixel electrode. The first TFT includes a first channel and a first semiconductor layer. The first channel includes two or more subchannels. The first semiconductor layer includes two or more semiconductor sublayers. Each of the semiconductor sublayers is disposed in a corresponding subchannel.
