Abstract: A display device includes a display panel including a data driver that converts input data into a data signal and supplies the data signal to an output line, a pixel unit including pixels that display an image based on the data signal, a demultiplexer including transistors electrically connected to the output line in the display panel, and transmitting the data signal from the output line to data lines electrically connected to the pixels, and a timing controller that supplies control signals to control a supply timing of the data signal. A number of the transistors are electrically connected in series, and others of the transistors are electrically connected in parallel.
