Accordingly, even when the driving module 400 is seated on the rear surface of the liquid crystal display panel 10, a predetermined pressure that may occur during the disposition process is not transmitted to the first electrode pad 110 and the second electrode pad 120. Support. In addition, as described above, the connector 300 is made of a material having a certain ductility or elasticity to absorb the pressure that may occur while the first signal line 410 and the second signal line 420 are bent to the first electrode. Pressure transmitted to the pad 110 and the second electrode pad 120 may be removed. Accordingly, the liquid crystal display of the present invention may support to prevent damage of the first electrode pad 110 and the second electrode pad 120.

Meanwhile, an outer length of the connector 300 to which the cover 340 and the case 330 are bonded is a step depth of an area where the first electrode pad 110 and the second electrode 320 of the liquid crystal display panel 10 are formed. Although described as corresponding to, the present invention is not limited thereto. That is, the length of the coupling direction of the cover 340 and the case 330 may be formed relatively small or relatively longer than the step depth. In the case of the connector 300 having a relatively longer length, the connector 300 may be formed of a flexible material to prevent breakage of the first electrode pad 110 and the second electrode pad 120.

In addition, in the above description, the structure of the connector 300 of the present invention has been described as a shape in which two electrodes are symmetrically crossed with each other, but the present invention is not limited to the structure of the connector 300 described above. That is, the connector 300 of the present invention may be connected to the first electrode pad 110 and the second electrode pad 120 to transmit a signal necessary for operating the color filter substrate 100 and the TFT array substrate 200. A connection part connected to a connection part and signal lines attached to the driving module 400 so as to transmit a signal of the driving module 400 to the color filter substrate 100 and the TFT array substrate 200 and a joint connecting the connection parts. It may be formed in various forms such as the form of an electrode pin or a dedicated clip including a portion.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. , And are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention can be carried out in addition to the embodiments disclosed herein.
