摘要： An objective lens (1) for an optical disk, which focuses a light beam from a light source, is designed so that a third-order coma aberration generated when the objective lens is inclined at a unit angle is larger than a third-order coma aberration generated when the optical disk (2) is inclined at the unit angle, mounted on an actuator for inclining the objective lens according to an inclination amount of the optical disk, and used. With this structure, it is possible to obtain an objective lens for an optical disk that has a large numerical aperture and is easy to manufacture and assemble, and in which the third-order coma aberration generated when the optical disk surface is inclined owing to a warp or the like can be corrected by small inclination of the objective lens, so as to reduce a residual astigmatism, which is generated according to the inclination amount, after the correction.

摘要： The present invention is intended to reduce a peak value of a momentary current, which is generated in a data driver, even when display data items expressing a succeeding display line have changed largely. The data driver includes: an internal control signal production circuit that groups multiple video lines into multiple blocks and produces internal control signals which are used to make the transmission timings of video voltages onto video lines, which belong to the blocks, different from one another among the blocks; a first latch circuit that sequentially latches display data items which express one display line and which are received successively externally; a second latch circuit that latches the display data items which have been latched into the first latch circuit; a third latch circuit that latches the display data items, which have been latched into the second latch circuit and are associated with the blocks, at timings, which are different from one another among the blocks, responsively to internal control signals; and a decoder that converts the display data items, which have been latched into the third latch circuit, into video voltages. The display data items latched into the first latch circuit are latched into the second latch circuit at timings which are different from one another among the blocks.
