Liquid crystal display with compensated pixel arrays
A liquid crystal display having one or more pixels, each of which includes a first sub-pixel operating at a first threshold voltage, and a second sub-pixel neighboring the first sub-pixel, and operating at a second threshold voltage. The first sub-pixel is divided into two separate portions by the second sub-pixel to form at least four domains of liquid crystal molecules illuminating at various gray levels for improving viewing angle characteristics of the liquid crystal display.
