Patent ID: 8493301

Claim:
A liquid crystal display device, comprising: a display panel including a pixel matrix in which pixels each including at least a switching element and a pixel electrode are arranged in matrix near intersection points of data lines and gate lines arranged longitudinally and laterally, and a counter electrode that is arranged to oppose the pixel matrix with a liquid crystal layer interposed therebetween; and a control part for dividing a period for displaying a color image of one frame into a plurality of sub-frame periods, and lighting up light sources of different colors for each of the sub-frame periods to display images according to the colors of the light sources on the display panel, wherein a shield electrode layer separated by an insulating film is disposed between the pixel electrode and the data lines, the shield electrode layer reduces a coupling of capacitances of the pixel electrode and the data line through shielding, and the control part applies a voltage to the shield electrode layer by changing a waveform for each of the sub-frame periods.
