ABSTRACT:
A display device includes a plurality of pixels, a plurality of signal lines connected to the plurality of pixels and a drive circuit connected to the plurality of signal lines. The drive circuit includes a distribution port and a decoder, wherein the distribution port distributes supplied data to corresponding circuit portions in the decoder, and the decoder selects gray scale voltages based upon the data from the distribution port. The distribution port includes a first switching stage having two switching elements and a second switching stage having four switching elements and which is electrically connected to the first switching stage. The decoder is disposed between the second switching stage and the plurality of signal lines.
