Abstract
A LCD device includes first and second LCD panels stacked one on another. Each of the first and second LCD panels includes a pair of transparent substrates, a liquid crystal layer sandwiched therebetween, and a pair of polarizing films sandwiching therebetween the pair of transparent substrates. A light diffusion layer having light diffusion function is interposed between the first LCD panel and the second LCD panel. The light diffusion layer reduces the intensity of the light passed by the first LCD panel, thereby alleviating the periodicity of the arrangement of dark areas and bright areas to alleviate the moire caused by light interference.
