An image signal processing circuit is provided that includes a display panel, a current detection section, a modification processing section, and a correction processing section. The display panel includes a first dummy pixel that is provided outside of an effective pixel region. The current detection section detects a change in a current in the first dummy pixel. The modification processing section modifies a predetermined predicted degradation value based on an actual degradation amount of the detected current. The correction processing section corrects an image signal based on the predetermined predicted degradation value after modification. The image signal is used to drive an effective pixel.
