Abstract:
1. A liquid crystal display, comprising: a liquid crystal panel assembly including a plurality of gate lines, a plurality of data lines intersecting the gate lines, a plurality of switching elements connected to the gate lines and the data lines, a plurality of pixel electrodes connected to the switching elements, and a reference electrode opposing the pixel electrodes; a gate driver for applying gate signals to the gate lines to activate the switching elements; a data driver for applying data voltages that are applied to the pixel electrodes to the data lines; and a reference voltage generator for generating more than two reference voltages to be respectively applied to more than two positions of the reference electrode, wherein the reference voltage generator comprises: a first group of resistors for dividing an external voltage; a first capacitor for storing an output voltage of the first group of resistors and providing the stored voltage as the second reference voltage; and an amplifier for amplifying the second reference voltage outputted from the first capacitor and outputting an amplified voltage as the first reference voltage.
