Abstract: An electro-optical device includes: a display panel module having electronic parts provided therein; and an insulating tape that is adhered to the display panel module so as to cover the electronic parts. The insulating tape includes an adhesive portion and a non-adhesive portion. The non-adhesive portion is disposed at a position that covers a region in which the electronic parts are provided, and the adhesive portion is adhered to the display panel module in regions other than the region in which the electronic parts are provided.

Abstract: Components for electronic displays containing a polyimide substrate and an electrical conductor are disclosed. The components are suitable for use in touch panel displays. The invention is also directed to electronic displays incorporating the components of the invention, and methods of making the display components. The combined polyimide substrate and electrical conductor are selected such that they have high internal radiation transmissivity, and typically have an effective radiation absorption coefficient of less than 0.02 per micron at wavelengths from 400 to 450 nm. In addition, the polyimide substrate permits processing of the display components at elevated temperatures, and usually has a glass transition temperature greater than 300° C.

Abstract: A thermally cured polyimide is provided, and in particular a crosslinked polyimide, comprising a fluorenyl diamine and comprising an aromatic ring having at least one C1-C10 branched or unbranched alkyl substituent, where the alkyl substituent includes a benzylic hydrogen. The present invention provides a crosslinked polyimide made by a process comprising the step of crosslinking a polyimide comprising diamines comprising pendent fluorenyl groups and comprising aromatic rings having at least one C1-C10 branched or unbranched alkyl substituent, the alkyl substituent including a benzylic hydrogen, by raising the temperature of said polyimide above its glass transition temperature.
