To provide an electronic circuit, an element substrate, an electronic device, an electro-optical device, and an electronic apparatus, which make it possible to perform a precise controlling operation even if manufacturing variations occur, a circuit formation area is an annular formation area of a pixel of a display panel, and does not include a substantially central portion of the pixel. A light emission area is provided in the substantially central portion. One drive circuit is formed in the circuit formation area, and four organic elements OLED are formed in the light emission area. The drive circuit and the organic elements OLED are connected parallel to each other with wirings.
