PROBLEM TO BE SOLVED: To provide a signal drive circuit for an active matrix type liquid crystal panel, enabling high picture quality to be compatible with low power consumption, a display device, an electro-optical device and a signal driving method using the signal drive circuit. SOLUTION: This signal driver (signal drive circuit) includes a shift register 140 shifting successively, by using as a unit a block which is devided for every a plurality of signal lines, image data in accordance with signal lines of the block, a line latch 36 latching the image data in synchronization with a horizontal synchronizing signal LP, a driving voltage generating circuit 38 generating driving voltages based on the image data and a signal line drive circuit 40 and in the driver, partial display is controlled based on partial display data PART which are specified in a block unit. The signal lines of the block set in a display area are driven based on the image data. Moreover, each signal line of block set in non-display areas is driven by the given non-display level voltage generated in a non-display level voltage supplying circuit.
