    Abstract: A method for correcting a mask pattern used for dry-etching an object with higher accuracy, and for manufacturing an acceleration sensor and an angular velocity sensor. The object is first etched by a dry-etching process using an uncorrected reference mask pattern. Then, distribution of the size of expansion of a tapered portion formed in a surface of the object is measured. Thereafter, the measured distribution is approximated by using a quadratic curve (Y=AX2+B) so as to determine A and B. Consequently, an amount t of correction for the tapered portion, which is expressed by the following equation (1) and related to a width of an opening of the mask pattern in a position at a distance r from a center of the object to be etched, can be set. In this way, the correction for the tapered portion can be carried out. t=(Ar2+B)/2  (1)

    Abstract: The invention relates to a liquid crystal display device which enables a visual field range to be made wide and luminance drops to be reduced, so that bright displayed images can be presented, and provides a liquid crystal display device comprising, in order from a side of backlight 11, backlight 11, scatter plate 12, and liquid crystal element 20, wherein a transmission type of hologram scatter plate 13 is located in front of a display surface of liquid crystal display element 20. Hologram scatter plate 13, because of having been fabricated by means of single-step or two-step exposure, enables light more or less scattered through scatter plate 12 to be limitedly scattered within a given wide visual field range, so that bright displayed images can be presented over a wide visual field range yet with a reduced luminance drop. Scatter plate 12 may be omitted.
