Abstract
The number of TFT ( ), thin film transistors for controlling the supplied power to an element to be driven such as an organic EL element ( ) which operates based on the supplied power, provided between the element to be driven and a power supply line VL, is equal to n, where n is an integer greater than or equal to two. The n TFTs ( ) and corresponding element to be driven ( ) are electrically connected by contact points, the number of which is less than or equal to (n−1). It is possible to improve the reliability as a semiconductor device and a display device, and, at the same time, to secure maximum actual operation region (illumination region for an illuminating element) of the element to be driven.
