Liquid-crystal display apparatus

---

Abstract

---

When time-division driving, which allows the number of output pins of a driver IC to be reduced, is applied to an active-matrix LCD apparatus, a time-division number is set to an odd number, preferably to the n-th (n: natural number) power of three, and a time-sequential signal (dot inversion signal) output from the driver IC is time-divided by a time-division switch and sent to signal lines 12-1, 12-2, 12-3, . . . to implement complete dot inversion driving.
