Patent ID: 8218116

Claim:
A liquid crystal display panel comprising: an array substrate having a display region and a mounting terminal portion formed at a periphery of the display region, the display region having a plurality of scanning lines and signal lines formed in a matrix, and a lower electrode and an upper electrode that has a plurality of slits, each of the lower and upper electrodes being made of a transparent conductive material formed on a planar film, and disposed opposite to each other with an insulator interposed therebetween in each region surrounded by the scanning lines and the signal lines, the mounting terminal portion including: a first insulator that covers a surface of a wiring for a mounting terminal, a contact hole formed so as to penetrate through the first insulator on the wiring for a mounting terminal, a first conductive film that at least covers part of a bottom portion of the contact hole and is electrically connected to the wiring for a mounting terminal, a second insulator that is provided on a surface of the first insulator, that covers a portion of the first conductive film, and has an opening at least part of which is overlapped with the contact hole in a planar view and a second conductive film that covers a surface of the second insulator around the contact hole such that a portion of the second insulator is formed between and directly contacts the first conductive film and the second conductive film, and a portion of the second insulator extends between the first conductive film and the second conductive film into an interior of the contact hole so as to cover a portion of the first conductive film at a bottom portion of the contact hole, and the first conductive film and the second conductive film being electrically connected in the opening, wherein the first conductive film and the second conductive film are formed of a same material as the lower electrode and the upper electrode, respectively, and the second insulator is formed of a same material as the insulator disposed between the lower electrode and the upper electrode.
