Circuit panel and flat-panel display device

A flat-panel display device comprising:

• first and second substrate;
• and
• an optical modulation layer held between said first and second substrate;
• wherein said first substrate includes first signal wirings, second signal wirings almost perpendicularly intersecting said first signal wirings, pixel transistors disposed near intersections of said first and second signal wirings, pixel electrodes electrically connected to said pixel transistors, and a driving circuit for the first and second signal wirings, said driving circuit including first and second output circuit sections which drive ends of each first signal wiring based on an input signal, each of the output circuits sections including a level shifter which level-shifts the input signal and a logic circuit which is formed of first and second circuit elements and is configured to output a first voltage or a second voltage according to a voltage signal from the level shifter;
• wherein the first and second circuit elements are configured with uneven driving capabilities in order to set the signal wiring to the first voltage immediately after power is supplied.

A circuit panel comprising:

• a signal wring formed on an insulating substrate;
• and
• first and second output circuit sections which drive ends of the signal wiring according to an input signal, each of the output circuit sections including a level shifter which level-shifts the input signal and a logic circuit which is formed of first and second circuit elements and is configured to output one a first voltage or a second voltage according to a voltage signal from the level shifter,
• wherein the first and second circuit elements are configured with different resistances from each other in order to set the signal wiring to the first voltage immediately after power is supplied.
