The present invention relates to an active matrix display device including a plurality of pixels and a source driver (23) which supplies image data (VIDEO), which has been externally supplied, to the plurality of pixels. Each of the plurality of pixels has: a data storing section (30) for storing the image data supplied from the source driver (23); a latch circuit (40) which latches, at a predetermined timing (LP signal), the image data which is stored in the data storing section (30); and a polarity reversing circuit (50) for reversing a polarity of the image data which is latched by the latch circuit (40). The image data, whose polarity is reversed by the polarity reversing circuit (50), is written into the each of the plurality of pixels. This makes it possible to improve a display quality by eliminating a difference of write time per pixel between frames.
