ABSTRACT:
A liquid crystal display device includes a driving voltage supply line connected to a transfer pad through a contact hole. The contact hole is corroded under the open air in a prior art liquid crystal display device. According to the present invention, however, the contact hole is provided in an air tight place ranging from an edge portion of a display area through a sealing material, e.g., underneath the sealing material. With this structure the contact hole is not exposed to the open air so that its resistance to corrosion is significantly improved.
