An electronic device can include a control circuit of a pixel, a first black layer including an opening, and a second black layer. The control circuit can lie at an elevation between the first black layer and the second black layer. A process of forming an electronic device can include forming a first black layer over a substrate, wherein the first black layer includes an opening. The process can also include forming a control circuit of a pixel over the substrate after forming the first black layer. The process can further include forming a second black layer over the substrate after forming the control circuit.
