ABSTRACT:
In a display device, a demultiplexer is used to transmit a data current to a data line. The demultiplexer includes a plurality of sample/hold circuits for sampling the time-divided and sequentially input current and holding them to the data line. A plurality of data lines coupled to the demultiplexer are coupled to pixels of the same color, and hence, currents with different levels are transmitted to pixels of different colors. A sample/hold circuit for transmitting a higher level current uses a driving transistor having a larger ratio of a channel width and a channel length.
