Abstract: A level shifter according to an embodiment and a display device using the same are discussed. The level shifter includes a driving signal generation circuit configured to output driving signals through signal lines, and a pseudo signal generation circuit configured to generate phase-inverted pseudo signals of the driving signals. The pseudo signal generation circuit can raise or lower a voltage level of the pseudo signals by a variation magnitude adjusted according to the driving signals whenever a section with the driving signals overlapping on a time axis occurs.
