The present invention relates to a flexible color filter. More specifically, the present invention is characterized in that a separation layer, a protective layer, a black matrix layer and a pixel layer are sequentially laminated, wherein the protective layer comprises one or more polymers selected from polymers represented by chemical formula 1 or chemical formula 2.

Flexible color filter

A film touch sensor includes a separation layer, a protective layer disposed on the separation layer, and an electrode pattern layer which is disposed on the protective layer and includes an insulation layer formed by curing an insulation layer forming composition comprising a polymer having a repeating unit represented by Formula 1 or 2, such that it is possible to suppress thermal damage which may occur in high-temperature deposition and annealing processes, and significantly reduce an occurrence rate of cracks during peeling-off the same from a carrier substrate.

Film touch sensor and method for fabricating the same

A film touch sensor includes a separation layer, a protective layer which is disposed on the separation layer and is a cured layer of a polymer having a repeating unit represented by Formula 1 or 2, and an electrode pattern layer disposed on the protective layer, such that it is possible to suppress thermal damage such as wrinkles, or cracks of an protective layer, which may occur in high-temperature deposition and annealing processes, and significantly reduce an occurrence rate of cracks during peeling-off the same from a carrier substrate.

A film touch sensor includes a separation layer; a protective layer disposed on the separation layer, and an electrode pattern layer which is disposed on the protective layer and includes an insulation layer that is a cured layer of a binder resin including (a-1) a resin in which at least a part of a phenolic hydroxyl group or a carboxyl group is protected with an acid decomposable group, (a-2) an acrylic resin containing an epoxy group, and (a-3) an acrylic resin containing an oxetane group, such that it is possible to suppress thermal damage such as wrinkles, or cracks of the insulation layer, which may occur in high-temperature deposition and annealing processes, and significantly reduce an occurrence rate of cracks during peeling-off the same from a carrier substrate.

A film touch sensor includes a separation layer, a first protection layer on the separation layer, and an electrode pattern layer on the first protection layer. An alkoxy group having 1 to 5 carbon atoms from the separation layer, and at least one substituent group of a hydroxyl group, a carboxyl group or an amide group from the first protection layer are reacted with each other to form a chemical bond between the separation layer and the first protection layer. Thus, electrode damages and cracks are prevented during a detaching process from a carrier substrate to improve flexibility and durability of the film touch sensor.
