An upper member of a pillar has a substantially U-shaped cross section, and includes first side walls extending substantially in a transverse direction of the vehicle at least at a lower portion, and a connecting plate at a lower end while keeping the U-shaped cross section. A lower member includes a mounting plate opposed to the connecting plate at a lower portion being lower than an upper end, and second side walls extending substantially in the transverse direction at both end portions of the mounting plate in a longitudinal direction of the vehicle. The connecting plate and the mounting plate are welded to each other in a state that they are in abutment with each other, and the first side walls and the second side walls are joined to each other, and the upper member and the lower member are integrally fixed to each other.

A susceptor includes a first step portion on which a wafer is placed; and a convex portion placed on a bottom surface of the first step portion, wherein a void is formed between a top surface of the convex portion and a rear surface of the wafer in a state in which the wafer is placed on the top surface of the convex portion.
摘要:
Electrode slit portions are formed in a pixel electrode in a direction of crossing a slit for dividing a liquid crystal layer into a plurality of domains. A titanium oxide film is formed so as to be exposed to the liquid crystal layer side via the electrode slit portions, the titanium oxide film having a relative dielectric constant higher than that of an organic film formed at positions corresponding to the electrode slit portions. By the titanium oxide film, an electric field of each domain is set, angles between the director in the vicinity of the electrode slit portion and transmission axes of polarizing plates are made to approximately 45°, and a decrease in transmittance caused by the falling direction of the director can be suppressed. The transmittance and contrast ratio are secured, and simultaneously an excellent wide viewing angle range can be obtained.
