A conventional liquid crystal display device displays an image by adjusting the light transmittance of a liquid crystal using an electric field. To this end, the liquid crystal display includes a liquid crystal panel in which liquid crystal cells are arranged in a matrix and a driving circuit for driving the liquid crystal panel.

Referring to FIG. 1, a conventional liquid crystal display device includes a liquid crystal panel 11 in which liquid crystal is injected between two substrates, pad electrodes 15 formed on one side of the substrate and connected to an external circuit, and a plurality of integrated devices. Printed Circuit Board connected to the pad electrodes 15 through a Tape Carrier Package (hereinafter referred to as "TCP") 12 on which integrated circuits 13 are mounted. 14, referred to as "PCB".

The liquid crystal panel 11 includes a spacer (not shown) for injecting liquid crystal between the upper substrate and the lower substrate and for maintaining a constant gap between the upper substrate and the lower substrate. The upper substrate of the liquid crystal panel 11 is formed with a color filter, a common electrode, a black matrix, and the like, not shown. In addition, signal lines such as data lines and gate lines (not shown) are formed on the lower substrate of the liquid crystal panel 11, and thin film transistors (hereinafter referred to as TFTs) are formed at intersections of the data lines and the gate lines. Is formed. The TFT switches the data signal to be transmitted from the data line toward the liquid crystal cell in response to the scan signal (gate pulse) from the gate line. The pixel electrode is formed in the pixel region between the data line and the gate line.

The pad electrodes 15 formed on one side of the lower substrate are divided into a data pad region and a gate pad region connected to the data lines and the gate lines, respectively.                         

Circuit components for driving the liquid crystal panel 11 are mounted on the PCB 14, and the circuit components are used to drive a plurality of integrated circuits 13 mounted on the TCP 12. Accordingly, the TCP 12 supplies data signals and scan signals from the plurality of integrated circuits 13 to the data lines and the gate lines, respectively.

As described above, the TCP 12 can increase the effective area of the liquid crystal panel 11 and the liquid crystal panel 11 by a tape automated bonding method (hereinafter referred to as "TAB"), which is relatively simple to mount. It is mounted on).

The TAB method uses an anisotropic conductive film (hereinafter referred to as "ACF") as an adhesive for bonding between the pad 12 of the TCP 12 and the liquid crystal panel 11.

The TAB process includes a process of manufacturing an ACF as shown in FIG. 2, an ACF attaching process of attaching the produced ACF on the pad electrodes 15 of the liquid crystal panel 11, and the process of the liquid crystal panel 11. It is divided into a TCP pressing process for TCP attachment on the pad electrodes 15 and a main pressing process for complete fixing between the pressed TCP and the ACF.

As shown in FIG. 3A, the ACF includes a conductive film 30 including conductive particles, and upper and lower protective films 32 attached to front and rear surfaces of the conductive film 30 to protect the conductive film 30. 34).

The upper and lower protective films 32 and 34 are attached to the upper and lower portions of the conductive film 30 to protect the conductive film 30 from foreign matters.                         

The ACF produced by the ACF manufacturing process is used as an adhesive for bonding the TCP 12 to the liquid crystal panel 11 by the TCP pressing process.

Accordingly, in the TCP pressing process, first, the lower protective film 34 is peeled off from the conductive film 30 and then placed on the pad electrode 15 of the liquid crystal panel 11 as shown in FIG. 3B.

Then, as illustrated in FIG. 3C, the upper protective film 32 attached to the upper surface of the ACF placed on the pad electrode 15 of the liquid crystal panel 11 is peeled off.

Subsequently, as shown in FIG. 3D, the TCP 12 having the integrated circuit 13 mounted on the ACF on which the upper protective film 32 is peeled off is aligned with the liquid crystal panel 11, and then the TCP press bonding process is performed. As a result, the TCP 12 is pressed onto the liquid crystal panel 11.

Finally, in the TCP main compression process, the TCP 12 pressed on the liquid crystal panel 11 is pressed at a temperature and a predetermined pressure of 160 to 180 degrees using a pressure tool not shown, as shown in FIG. 3E. do. Accordingly, the conductive particles in which the conductive film 30 of the ACF is melted by the temperature and the pressure of the pressing tool are injected with the pad electrodes 15 of the liquid crystal panel 11 and the electrodes 45 of the TCP 12. It is protected between to obtain conductivity. In addition, the ACF is charged between the pad electrodes 15 of the liquid crystal panel 11 to maintain high insulation because the conductive particles exist independently of each other. Mechanical fusion between the conductive particles of the ACF and the electrodes 15, 45 is maintained by the high adhesion of the ACF. Accordingly, the electrodes 45 of the TCP 12 are electrically connected to the pad electrodes 13 of the liquid crystal panel 11 through the conductive particles of the ACF.                         

In this TAB process, the TCP 12 and the liquid crystal panel 11 are adhered to each other using ACF as a medium. However, when the ACF deflection occurs when the ACF is attached to the large-area substrate, the adhesion between the TCP 12 and the liquid crystal panel 11 may not be completed.
