Disclosed are a light modulation apparatus including a liquid crystal device; and a polarizing plate disposed in an optical path of light made incident on said liquid crystal device; wherein said liquid crystal device is of a guest-host type using a negative type liquid crystal as a host material, an image pickup apparatus using the light modulation apparatus, and methods of driving the light modulation apparatus and image pickup apparatus.
摘要:
The present invention relates to a liquid crystal device of the type which comprises a pair of substrates (1a, 1b), and a liquid crystal (5) provided between the paired substrates (1a, 1b) wherein fine domains whose threshold voltages for switching the liquid crystal (5) are different from one another are finely distributed in said liquid crystal (5). In this liquid crystal device, fine particles (10) are added to said liquid crystal (5), whereby said fine domains whose threshold voltages are different from one another are formed.
摘要:
In a liquid crystal device in which a pair of substrates each having an electrode and a liquid crystal orientation control layer are disposed opposite to each other leaving a predetermined gap therebetween and liquid crystal is disposed in the gap, a plurality of grooves are formed on each of the inner surface contacting the liquid crystal, the section of the inner surfaces in a direction along the grooves has such a shape that repetitive asymmetrical projections are formed and the radius of curvature of the grooves in a direction intersecting the grooves is set to 0.1µm or more.
