Abstract

The present disclosure discloses a source driver including a level shift circuit. The source driver may include a level shift circuit outputting second and third logic signals by shifting a level of a first logic signal and a multiplexer transferring a first or second source signal to a first or second pad in response to the second and third logic signals. The level shift circuit may include a first level shifter outputting first and second input signals by shifting the level of the first logic signal, a second level shifter outputting third and fourth input signals by shifting the level of the first logic signal, and an output circuit outputting the second logic signal in response to the second and fourth input signals and outputting the third logic signal in response to the first and third input signals.
