PROBLEM TO BE SOLVED: To provide a drive circuit that reduces a layout area without lowering accuracy of gradation voltage and reducing the number of gradations, and to provide an electro-optical device, an electronic apparatus, and a driving method. SOLUTION: The driving circuit for driving source lines of the electro-optical device based on a gradation data of j-bits (j: an integer larger than one) includes: a gradation voltage generation circuit for supplying pre-buffer voltage selected from among at least 2<SP>j</SP>kinds of gradation voltages and 2<SP>k</SP>kinds of gradation voltages of continuous gradation values to each of 2<SP>(j-k)</SP>(0<k<j, k: an integer) pieces of gradation signal lines in time-division manner in one selected period; a voltage selection circuit for selecting one gradation signal line from among the gradation signal lines based on high order (j - k)-bits data of the gradation data; an output buffer for driving the source lines based on the gradation voltages of the gradation signal lines selected by the voltage selection circuit; and a switch element for by-passing the input and output of the output buffer.
