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.
