Paper Abstract:	Multilayer liquid crystal display (LCD) is a display device constructed by stacking multiple layers of liquid crystal on top of a light source. Since the total number of pixels in a multilayer LCD is larger than that of a single layer LCD, a multilayer LCD can store more information than a single layer LCD. Moreover, a multilayer LCD can show varying images depending on the viewers' eye positions. This property is found to be useful for autostereoscopic 3D viewing, which is elaborated upon in this paper. We have developed an algorithm for controlling the pixels in a multilayer LCD so that the rays of light emitted from the display will form an approximation of the light field of a 3D scene. The quality of the approximation depends on the configuration of the display, and parameters that have substantial effects on the quality have been identified through simulation-based studies. Comparison of our method with other autostreoscopic method is also carried out showing that our method can achieve better image quality while using smaller number of pixels.
