ABSTRACT:
A driving circuit of an electro-optical panel includes a shift register circuit to sequentially output transmission signals, a sampling circuit to sample an image signal by using a sequentially-output n-th (n is a natural number greater than or equal to 2) transmission signal as a sampling-circuit driving signal and writing the sampled image signal to data lines, and a precharge circuit to write a precharge signal of a predetermined potential to the data lines prior to supplying the image signal to the data lines by using a sequentially-output (n−1)-th transmission signal as a precharge-circuit driving signal, all of which are formed on a substrate.
