摘要： A liquid crystal device has a pair of oppositely disposed substrates and a liquid crystal having chiral smectic C phase disposed therebetween. The liquid crystal is placed in an alignment state in chiral smectic C phase with smectic molecular layers forming a chevron structure. Under no electric field application, the liquid crystal has an average molecular axis substantially in alignment with the uniaxial alignment axis and/or a bisector of a maximum angle formed between two extreme molecular axes established under electric field application, while under electric field application, the liquid crystal provides an effective tilt angle and a transmittance that continuously changes depending on an electric field applied thereto.

摘要： A liquid crystal device is constituted by a pair of substrates and a liquid crystal disposed in a uniform alignment state between the substrates. At least one of the substrate has a surface contacting the liquid crystal and including a first region having a larger uniaxial alignment control force and a second region having a smaller or substantially no uniaxial alignment control force, respectively acting on the liquid crystal. In the device, phase transition from liquid phase to mesomorphic phase on temperature decrease, of the liquid crystal has been initiated from a portion contacting the first region and enlarged toward the second region to place the liquid crystal in a uniform alignment state, thus ensuring an increased effective voltage applied to the liquid crystal while retaining a good alignment characteristic to improve drive and display characteristics.

摘要： A photoacoustic apparatus obtains information on a specimen by receiving photoacoustic waves which are generated from the specimen resulting from light irradiated to the specimen. The apparatus includes a light source for irradiating light to the specimen, an acoustic wave receiver for receiving the photoacoustic waves, and a light reflection member for causing the light, which is radiated out of the specimen by optical diffusion thereof after having entered an interior of the specimen from the light source, to reenter the interior of the specimen, wherein the light reflection member allows elastic waves to pass therethrough. As a result, a photoacoustic apparatus and a probe are provided which can confine scattered light from the specimen into the specimen, and which can reliably prevent photoacoustic waves from being generated from a receiving element region of the probe by the scattered light.
