Patent ID: 8264444

Claim:
A display device, comprising: a pixel electrode; a transistor supplying a driving voltage to the electrode pixel; and a gate-line driver circuit providing a gate voltage to the transistor and alternately inverting the driving voltage supplied to the pixel electrode via the transistor between a first driving state and a second driving state, wherein the driving voltage in the second driving state is inverted with respect to the driving voltage in the first driving state, wherein the gate-line driver circuit drives the transistor with a first level of the driving voltage in the first driving state and the gate-line driver circuit drives the transistor with a second level of the driving voltage in the second driving state, and wherein the gate-line driver circuit includes: a gate-voltage generating circuit generating the gate voltage to drive the transistor in response to the driving voltage; a level shift circuit converting a first level of the gate voltage generated by the gate-voltage generating circuit into a second level of the gate voltage in response to the second level of the driving voltage; and a switching circuit outputting the first level of the gate voltage in the first driving state, and outputting the second level of the gate voltage level-shifted by the level shift circuit in the second driving state; wherein the gate voltage has different base voltage levels between the first driving state and the second driving state.
