Abstract
In a liquid crystal display device that carries out image display using multiple liquid crystal panels stacked, the average change in the direction of the optical axis due to the response of liquid crystal molecules with respect to the applied voltage, that is, the change in the direction of the long axis of the liquid crystal molecules with respect to the applied voltage, is made different among the liquid crystal panels. The desired brightness is attained at the overlaid portion of the liquid crystal panels.
Claims10
A liquid crystal display device, comprising:
- stacked multiple liquid crystal panels, each of which comprises a sealed liquid crystal material;
- and
- a voltage applying unit that applies a voltage to the stacked multiple liquid crystal panels, wherein
- the sealed liquid crystal material has an average direction of optical axis that changes in response of liquid crystal molecules with respect to the voltage applied on the multiple liquid crystal panels by the voltage applying unit, and the changed average direction of the sealed liquid crystal material comprised by one of the stacked multiple liquid crystal panels is different from the changed average direction of the sealed liquid crystal material comprised by another of the stacked multiple liquid crystal panels.
