Filed: 1987-10-07
Abstract: PURPOSE:To form a multi-domain orientation thereby realize uniform display characteristics and a high contrast ratio, by using a liquid crystal composition containing a specified substance having two or more asymmetric carbon atoms in the molecular chain. CONSTITUTION:In a liquid crystal electro-optical device wherein a liquid crystal composition containing a ferromagnetic liquid crystal is put between electrodes and between a pair of parallel base plates forming an orientation section for an initial arrangement of liquid crystal material, said liquid crystal composition contains a substance of formula I, wherein R1 is a hydrocarbon group (e.g., a group of formula II) and R2 is a hydrocarbon group having two or more asymmetric carbon atoms in the molecular chain (e.g., a group of formula III). This enables the multi-domain orientation to be formed between said parallel base plates, thus giving a uniform orientation as a whole without the occurrence of zigzagging etc., so that uniform display characteristics and a high contrast ratio can be realized. Furthermore, uniform liquid crystal drive as a whole becomes possible because of the uniformity of inversion characteristics of the multi-domains.

IPC: G11B7/09
Filed: 1990-09-26
Abstract: PURPOSE:To miniaturize a light pickup and to make it light in weight by forming a semiconductor laser, a mirror deflecting a laser beam emitted from this laser and an actuator for driving it on the common substrate. CONSTITUTION:A voltage based on a tracking error signal is applied to an electrode 4f and the electrode 4e of the rear side of a moveable part 4c. An electrostatic attraction is generated between the electrode 4e and the electrode 4f, and a mirror 4a rotates to the counterclockwise direction of a figure. On the other hand, when the voltage based on the tracking error signal is applied to an electrode 4g and the electrode 4e, the mirror 4a rotates to the clockwise direction. Thus, the advancing direction of the laser beam reflecting by the rotated mirror 4a is changed, and the deviation value of an irradiating beam after passing an objective lens 7 from a track on an optical recording medium is corrected. Since the position of the laser beam to be made incident to the mirror 4a is always same, it is possible to reduce the area of the mirror 4a and accordingly an actuator 4 can be miniaturized.
