- Conductive materials such as anisotropic conductive films are widely used for connection to the array substrate and connection between the circuit substrate on which the source driver is mounted and the TFT array substrate of the liquid crystal display panel.
- connection method using the anisotropic conductive film is as follows.
- An anisotropic conductive film is a member having a predetermined thickness and formed in an elongated strip shape, and both surfaces in the thickness direction are adhesive surfaces.
- the anisotropic conductive film is heated and pressurized to such an extent that it does not cure (this process is referred to as “pre-bonding”).
- pre-bonding One circuit board and the other circuit board are temporarily bonded by temporary bonding.
- post-bonding the anisotropic conductive film is heated and pressurized again (this process is referred to as “post-bonding”).
- the anisotropic conductive film is also subjected to a force in the direction of peeling from the surface of the connection region. For this reason, if the anisotropic conductive film attached to the surface of the connection region of one circuit board is not sufficiently in close contact with the surface of the connection region, it is actually anisotropic in the process of peeling the separator. There is a possibility that the conductive film is peeled off from the surface of the connection region.

It can be done.
- the anisotropic conductive film does not exhibit the “anchor effect” (or the effect is small). For this reason, it is considered that the connection strength between the anisotropic conductive film and the connection region cannot be sufficiently improved.
- the “anchor effect” refers to an effect that the anisotropic conductive film bites into the unevenness formed on the surface of the connection region, so that the connection strength is improved because the anisotropic conductive film hardly peels off.
- the anisotropic conductive film in the step of attaching the anisotropic conductive film to the surface of the connection region of one circuit board, air may be trapped between the anisotropic conductive film and the connection region to form bubbles. .
- the anisotropic conductive film may not be connected to the surface of the connection region even if the portion where the bubbles are formed is pressurized. Therefore, there is a risk that the reliability of the electrical connection is lowered and the physical connection strength is lowered.
