Abstract: A circuit for generating a driving voltage and an LCD(Liquid Crystal Display) device having the same are provided to prevent distortion of images by outputting a gate voltage which is inversely proportional to ambient temperature, and a source voltage irrespective of the ambient temperature. A circuit for generating a driving voltage includes a switch voltage generator(510), a temperature compensation feedback unit(520), and a regulator(540). The switch voltage generator boosts up an external voltage(VCC) in response to a feedback voltage(VFB) and outputs a switch driving voltage(VSW) corresponding to the variation of ambient temperature. The temperature compensation feedback unit receives the switch driving voltage, compensates for the temperature variation, and outputs the feedback voltage. The regulator receives the switch driving voltage, and outputs a source voltage(AVDD) for maintaining a constant level irrespective of the temperature variation.

A reset circuit includes a signal delay unit(20) and a voltage stabilizing unit(30). The signal delay unit delays a first input voltage by a predetermined time and generates a delay signal.

The signal delay unit is an R-C time constant circuit. The signal delay unit includes a step-down unit, which decreases the first input voltage and supplies the result to the signal delay unit.
