AI Technical Summary

Problems solved by technology

For contact resistance, adhesion, etc., depending on the storage conditions of the film, the contact resistance of the film measured in the initial state may be increased, or its adhesion may be reduced, resulting in poor connection reliability
In addition, air bubbles are generated in the terminal when using the film, which also leads to a decrease in connection reliability
Also, the conventional anisotropic conductive film is cured at 160°C or higher, so heating and pressing require a lot of time

Abstract

An optical member includes an anisotropic conductive film that has a multilayer structure having a bonding layer containing an epoxy resin as a curing part and a bonding layer containing a (meth)acrylate resin as a curing part.

Description

technical field [0001] The present invention relates to an optical element including an anisotropic conductive film. More specifically, the present invention relates to an optical element comprising an anisotropic conductive film having a multilayer structure consisting of an adhesive layer comprising an epoxy resin as a curing portion and a (meth)acrylate resin Composition of bonding layer as a cured part, thereby minimizing panel deformation by low-temperature pressing while reducing process time, and improving connection reliability and adhesion of contact resistance. Background technique [0002] With the recent trend toward larger and thinner displays, the spacing between electrodes and circuits has become increasingly precise. Anisotropic conductive films play a very important role as wiring materials connecting fine circuit terminals. As a result, anisotropic conductive films have attracted much attention as electrical connection materials. [0003] Anisotropic con...
