Electronic device including detection element and insulation layer recess structure

An electronic device, comprising:

• a substrate;
• an active element, disposed on the substrate;
• a first insulation layer, disposed on the active element;
• a detection element, disposed on the first insulation layer, wherein the detection element comprises a lower electrode disposed on the first insulation layer, an active layer disposed on the lower electrode and an upper electrode disposed on the active layer, the lower electrode is a part of a conductive layer, wherein the active layer is disposed between the lower electrode and the upper electrode,
• wherein the first insulation layer has a recess, and the recess does not overlap with the conductive layer in a normal direction of the substrate,
• wherein in the normal direction of the substrate, a first portion of the first insulation layer overlaps with the conductive layer and has a first thickness, a second portion of the first insulation layer does not overlap with the conductive layer and has a second thickness, and the second thickness is less than the first thickness,
• wherein in the normal direction of the substrate, the recess overlaps with at least a portion of a channel area of the active element and the second portion, and the recess does not overlap with the detection element and the first portion;
• and
• a second insulation layer, disposed between the active layer and the lower electrode, wherein the second insulation layer has another recess, and in the normal direction of the substrate, the another recess does not overlap with the active layer.
