  • Patent number: 7550326
    Abstract: The present invention relates to a method for manufacturing a thin film device. The thin film device is manufactured by bonding a second substrate (106) to a thin film device layer (103) provided on a protective layer (102) formed on a first substrate (101) through a first adhesive layer (105), then, completely or partly removing the first substrate (101) in accordance with a process including at least one process of a chemical process and a mechanical polishing process, bonding a third substrate (109) to the exposed protective layer (102) or the protective layer (102) covered with the partly removed first substrate (101) through a second adhesive layer (108) and separating or removing the second substrate (106). Thus, the thin film device suitable for a light and thin display panel is manufactured without deteriorating a ruggedness.

  • Publication number: 20080225214
    Abstract: A difference in brightness between a portion, at which fiber overlaps, and any other portion of a plastic substrate in which a fiber cloth is contained is eliminated by setting the axis of the fiber and the optical axis of a polarizing plate so as to be coaxial with each other. Thereby, a normal displaying can be effected.
