Active element array substrate

The invention discloses an active element array substrate, and the array substrate comprises a substrate, a first circuit layer, a first insulating layer, a plurality of semiconductor layers, a secondcircuit layer, a second insulating layer, a transparent conductive pattern layer and a plurality of pad layers. The first insulating layer covers the first circuit layer and the substrate. The semiconductor layer is located on the first insulating layer. The second circuit layer is located on the first insulating layer. The second insulating layer covers the second circuit layer and the semiconductor layer. The transparent conductive pattern layer is located on the second insulating layer and has a plurality of gap regions. Each of the gap regions is formed between adjacent edges of the transparent conductive pattern layer and overlaps the first circuit layer, but does not overlap the second circuit layer and the semiconductor layer. The pad layers are sandwiched between the first insulating layer and the second
