Abstract:
A liquid-crystal display apparatus comprising:a first substrate in which are formed a pixel section having pixel electrodes and a driving section having a driving circuit for driving the pixel section;a second substrate disposed opposing said first substrate with a predetermined gap therebetween; anda liquid-crystal layer held between said first substrate and said second substrate;wherein the driving circuit comprises a transistor having a gate length of nL and a gate width of nW, n being any integer exceeding one, where L indicates the shortest gate length at which a desired dielectric strength can still be achieved, and W indicates a gate width obtained from a predetermined ratio of W/L,wherein reducing L thereby reduces circuit size, while setting n to exceed one reduces circuit malfunction caused by uneven silicon grains;wherein the driving circuit handles an analog signal and serves as a voltage level conversion circuit for converting an input-signal level.
