Abstract:
1. A display apparatus, including: a driving transistor which drives an optical element; and a switching transistor which is fed a control signal at its gate and sets data in said driving transistor in accordance with the control signal, wherein: characteristics of said transistors related to a current driving capability are made to differ from each other; the characteristic of said driving transistor related to a current driving capability is smaller than that of said switching and said switching transistor is comprised of n transistors (n being an integer greater than or equal to two), connected in series with each other, whose characteristics related to a driving capability are substantially equal to each other, wherein gate length of said switching transistor is substantially equal to that of said driving transistor, and wherein said driving transistor is formed in a manner such that gate width of which is narrower than 1/n of that of a transistor constituting said switching transistor.
