Abstract: A display device includes a display panel including data lines, a data driver outputting a data voltage to be supplied to the data lines to a source line, and a multiplexer distributing the data voltage received from the source line to the data lines in response to an enable signal received through an enable signal line. The multiplexer includes a plurality of switching elements each including a drain electrode connected to the source line, a source electrode connected to the data line, and a gate electrode supplied with the enable signal. The enable signal is transferred from the enable signal line to the gate electrode via an enable signal pattern. The enable signal pattern is disposed on a metal layer different from the switching elements with an insulating layer interposed between them in a formation area of the switching elements.

Abstract: A gate driver and a display device including the same are discussed. The gate driver includes a plurality of stages. Each stage includes a transistor T1 configured to apply a start signal to a node Q, a transistor Tu configured to output an emission signal of a gate low voltage to a node Na depending on a voltage of the node Q, a transistor T5 configured to control a voltage of a node QB to be reversed to the voltage of the node Q, a transistor Td configured to output the emission signal of a gate high voltage higher than the gate low voltage to the node Na depending on the voltage of the node QB, and a transistor Tbv connected between the transistor T1 and the node Q and configured to stabilize the voltage of the node Q.
