Abstract
EL display elements are configured by sequentially laminating an anode, an emissive layer and a cathode, and emit light of R, G, and B. Each EL display element is supplied with a drive current from an EL element driving TFT. The transistor sizes of the EL element driving TFTs connected to the display pixels for respective colors are designated such that the size of the TFT for a green display pixel including an EL element having the highest emissive efficiency is the smallest, and the sizes of the TFTs for red and blue display pixels having sequentially decreasing emissive efficiency are made sequentially larger.
