Abstract: A display panel and a demultiplexer circuit are provided. The demultiplexer circuit includes a first to a Pth switch units. The first to the Pth switch units are coupled to a first to a Pth data lines of a display panel respectively and collectively receive a data voltage and turn on sequentially in sequence to provide the data voltage to corresponding data lines. A period of the first to the Pth switch units provide the data voltage to the first to the P data lines sequentially which is defined to a data transmission period. When the switch unit is turned on, N transistors are turned on simultaneously according to a plurality of control signals. When the switch unit is turned off, at least one of the N transistors is turned off according to a corresponding control signal.
