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.

Claims (8)

1. A liquid crystal display (LCD) device comprising:

first and second LCD panels each including a pair of transparent substrates and a liquid crystal (LC) layer sandwiched therebetween,

said first and second LCD panels being stacked one on another so that each pixel of said first LCD panel overlaps a corresponding pixel of said second LCD panel,

said pixels of said first and second LCD panels each include a bend and a pair of stripes extending from said bend, said bend of each pixel of said first LCD panel is deviated in angular position from the bend of the corresponding pixel of said second LCD panel by a specific rotational angle.

2. The LCD device according to claim 1 , wherein said specific rotational angle is larger than zero degree and smaller than 180 degrees.

3. The LCD device according to claim 1 , wherein said specific rotational angle is substantially 90 degrees.

4. The LCD device according to claim 1 , wherein each pair of transparent substrates include an active substrate on which active devices for driving said LCD layer are formed and a counter substrate, and at least one of said counter substrates of said first and second LCD panels is interposed between said active substrate of said first LCD panel and said active substrate of said second LCD panel.

5. The LCD device according to claim 1 , wherein each pair of transparent substrates includes a counter substrate, at least one of said counter substrates of said first and second LCD panels has a color filter mounted thereon.
