摘要： A liquid crystal display device according to the present invention is constituted of a TFT substrate and an opposing substrate which are arranged so as to be opposite to each other with a liquid crystal layer interposed therebetween. In addition, in the liquid crystal layer, formed is a polymer into which a polymer component added to liquid crystal is polymerized, and which determines directions in which liquid crystal molecules tilt when voltage is applied. In the TFT substrate, formed are a sub picture element electrode directly connected to a TFT and a sub picture element electrode connected to the TFT through capacitive coupling. In each of these sub picture element electrodes, formed are slits extending in directions respectively at angles of 45 degrees, 135 degrees, 225 degrees and 315 degrees to the X axis.

摘要： An optical device (100) includes a first substrate (10) and a second substrate (20), and an optical layer (30) interposed therebetween. The first substrate includes a first electrode (11) and a second electrode (12), to which respectively different potentials can be applied. The optical layer (30) contains a medium (31P) and anisotropically-shaped particles (32) whose alignment direction changes in accordance with the direction of an electric field applied to the optical layer. The medium is a liquid crystal material. When no electric field is applied to the optical layer, the anisotropically-shaped particles are aligned substantially vertically with respect to the substrate plane.

摘要： In a liquid crystal display device, liquid crystal molecules are oriented in a vertical direction to the first substrate and the second substrate by the first molecule orientation film and the second molecule orientation film, respectively, in a non-driving state. A structural pattern is formed so as to extend in a first direction parallel a surface of the liquid crystal layer and so as to form, in a driving state, an electric field periodically changing in a second direction that is parallel to the liquid crystal layer and vertical to the first direction. The liquid crystal molecules substantially tilt in the first direction in the driving state.
