The inventors have intensively studied and found that an electrostatic indicator that can visualize the magnitude of its charge potential can be provided by using a liquid crystal composition and forming multiple regions in which the alignment of the molecules of the liquid crystal composition differently changes in response to electric potential. Furthermore, there is provided an electrostatic indicator that can be placed in a two-dimensional or three-dimensional manner to also visualize spatial distribution of high or low charge potential.

There is provided a liquid crystal display device of a PSA type or the like that uses the polymerizable compound-containing liquid crystal composition, having a sufficiently fast response speed, capable of 3D displaying. Uniform and stable orientation control can be obtained at a lower energy cost. Provided are the polymerizable compound-containing liquid crystal composition containing one or two or more polymerizable compounds represented by general formula (M) as the first component, and containing one or two or more compounds represented by general formula (Na), general formula (Nb), or general formula (Nc) having a naphthalene unit as the second component. The liquid crystal display device uses the same.

Polymerizable-compound-containing liquid crystal composition and liquid crystal display element using same

The present invention relates to a PSA-mode liquid crystal display device including a polymer produced by polymerizing a polymerizable compound by energy ray irradiation in a state in which a mixture of the polymerizable compound and a liquid crystal composition is held between the first substrate and the second substrate, the polymer having a number-average molecular weight of 50,000 or more in terms of polystyrene. In a PSA-mode display device in which alignment of liquid crystal molecules substantially vertically aligned between the substrates is controlled by applying a voltage, a pre-tilt angle can be properly given without being inhibited. Therefore, the present invention provides a PSA-mode display device with good alignment stability, uniform alignment within the substrates, and no or suppressed display defects and a method for producing the same.
