Abstract
A TFT for controlling the power supplied to an element to be driven, such as an organic EL element which operates based on the supplied power, is provided between the element to be driven and a power supply line VL. The TFT and the element to be driven are electrically connected by a wiring layer. The contact position between the wiring layer and the TFT and the contact position between the wiring layer and the element to be driven are positioned so as to be distant from each other. Alternatively, at least the contact hole region of a first electrode of the element is covered by a flattening layer. With this structure, it is possible to realize a flatter surface on which to form, for example, the emissive layer of the element to be driven.
