Abstract: An active-matrix circuit board includes a substrate including an avoided portion in a predetermined region thereof, one or more first pixel electrodes disposed around the avoided portion on the substrate, second pixel electrodes disposed on the substrate, pixel-driving circuits disposed on the substrate to drive the first and second pixel electrodes, wiring lines disposed on the substrate and connected to the pixel-driving circuits, and bypass line portions provided in the wiring lines so as to bypass the avoided portion. The first pixel electrodes are larger than the second pixel electrodes and have such a shape as to extend toward the avoided portion. The bypass line portions are disposed under the first pixel electrodes.
