Abstract:
1. A liquid crystal display panel comprising a plurality of pixel regions arranged in a matrix, each pixel region including: a gate line; first and second data lines crossing the gate line; a first thin film transistor connected to the gate line and the first data line that applies a voltage on the first data line to a liquid crystal cell between the first and second data lines; and a second thin film transistor connected to the gate line and the second data line that applies a voltage on the second data line to the liquid crystal cell, wherein the liquid crystal display panel includes a switching unit that alternately applies a data voltage and a common voltage to each of the first and second data lines, wherein the switching unit alternately applies the data voltage and the common voltage in response to first and second control signals to the first and second data lines, wherein drain electrodes of the first and second thin film transistors are connected in common to the liquid crystal cell, wherein the data voltage and the common voltage are alternately supplied to the first and second data lines of each pixel region for a predetermined period, wherein the switching unit includes a plurality of switches respectively corresponding to each pixel region, each of the switches includes first through fourth transistors being one of NMOS type transistor and PMOS type transistor, wherein the first and fourth transistors are connected to a first control signal line to which the first control signal is supplied, wherein the first transistor supplies the data voltage to the first data line and the fourth transistor supplies the common voltage to the second data line simultaneously, and the second and third transistors are connected to a second control signal line to which the second control signal is supplied, wherein the second transistor supplies the common voltage to the first data line and the third transistor supplies the data voltage to the second data line simultaneously.
