摘要

PROBLEM TO BE SOLVED: To solve a problem of slow writing speed occurring when data current is reduced for the purpose of displaying low gradation.

SOLUTION: An electronic circuit is provided with a programming route and a reproduction route. The circuit includes a current driving element, a transistor arranged in a production route for the purpose of operating to control current to be supplied to the current driving element, a capacitative element arranged for storing operating voltage of the transistor, an additional transistor arranged parallel to the transistor in the production route so as to store the operating voltage in the capacitative element, and a switching means for controlling the programming route and the reproduction route.
