In a liquid crystal display with improved side visibility and a fabrication method of the liquid crystal display, a unit pixel may include first and second sub-pixels in which liquid crystals are continuously aligned and electrically isolated. A first pixel electrode for implementing the first sub-pixel is formed on a protective layer. A second pixel electrode for implementing the second sub-pixel is formed beneath the protective layer. The protective layer formed on the second pixel electrode lowers the electric field of the second sub-pixel, so that a liquid crystal application voltage applied to the second sub-pixel is lower than the voltage applied to the first sub-pixel. Accordingly, the transmittances of the first and second sub-pixels in the unit pixel are different from each other to improve side visibility.

In an LCD apparatus, a reflecting plate, which is formed on a pixel electrode connected to a switching device formed on an array substrate, defines a first area from which a natural light is reflected and a second area through which an artificial light is transmitted. The reflecting plate is partially extended to and overlapped with the second area depending upon a rubbing direction of the array substrate. Thus, the reflective-transmissive type LCD apparatus may prevent occurrence of the afterimage, and may enhance a contrast ratio thereof when operated in a transmissive mode.
