碩士 === 國立交通大學 === 電子物理系所 === 97 === The widely-used mechanical rubbing alignment in a liquid crystal
display has some disadvantages such as leaving the debris, scratches
and surface electrostatic charge. To avoid these drawbacks, Argon ion
beam treating surface of polyimide (PI) film in favor of and pretilt angle
controlling has been studied.
An ability of inducing high pretilt angle is observed in this work. The
aggregation of Fe2O3 deposit on surface due to high energy and long
time ion beam bombarding. Therefore, influences of treating time and
plasma energy on the alignment are discussed. To realize the
mechanism of surface alignment with pretilt angle, the relation between
the surface roughness and particle size has been characterized by
atomic force microscope (AFM) and scanning electron microscope
(SEM). Further investigations on the chemical bond on the treated
surfaces have been carried out by x-ray photoelectron spectroscopy
(XPS).
