Abstract: A liquid crystal display has an increased aperture ratio achieved by an increased area surrounded by the pixel electrode in a pixel area. However, this may result in poor image quality due to the excited interference voltage that is generated by parasitic capacitance created by the overlap of the pixel electrode and the data lines. At different portions of the data lines, the area of overlap between the pixel electrode and the data lines are different. Thus, to eliminate the excited interference voltage and enhance image quality, the thickness of the dielectric member between the pixel electrodes and the data lines is different so that the parasitic capacitance of the parasitic capacitors is about the same.
