Abstract
A multilayer film comprising an aromatic polyester layer and a silicone resin layer formed on at least one surface of the aromatic polyester layer. The multilayer film has excellent transparency, heat resistance, dimensional stability, mechanical strength and optical property and an improved solvent resistance, and is useful as a material of a liquid crystal display panel.
Claims9
A multilayer film comprising a layer of an aromatic polyester and a layer of silicone resin wherein said aromatic polyester comprises recurring units of the formula (I):
- ##STR3## wherein X is a bivalent group selected from the group consisting of a bivalent hydrocarbon group having 1 to 10 carbon atoms, --O--,--S--,--SO.sub.2 -- and--CO--, R and R' are a monovalent group selected from the group consisting of alkyl, aryl, aralkyl, alkoxyl, aryloxyl and arylalkoxyl groups having 1 to 20 carbon atoms, their substituted groups, a halogen atom, and a mixture thereof, p and q are 0 or an integer satisfying the equation:
- p+q=0 to 8, and m and n are 0 or 1, but n is not 0 when m is 1.
A liquid crystal display panel comprising a layer of an aromatic polyester, a layer of a silicone resin and a transparent conductive layer formed on the silcone resin layer wherein said aromatic polyester comprises recurring units of the formula (I):
- ##STR5## wherein X is a bivalent group selected from the group consisting of a bivalent hydrocarbon group having 1 to 10 carbon atoms, --O--,--S--,--SO.sub.2 -- and --CO--, R and R' are a monovalent group selected from the group consisting of alkyl, aryl, aralkyl, alkoxyl, aryloxyl and arylalkoxyl groups having 1 to 20 carbon atoms, their substituted groups, a halogen atom, and a mixture thereof, p and q are 0 or an integer satisfying the equation:
- p+q=0 to 8, and m and n are 0 or 1, but n is not 0 when m is 1.
