Embodiment Construction

[0056] Hereinafter, various embodiments of the present invention will be described in detail with reference to the drawings. The substrate for a display panel of each embodiment of the present invention is a TFT array substrate suitable for an active matrix type liquid crystal display panel.

[0057] figure 1 It is an external perspective view schematically showing the schematic structure of the display panel substrate 1 according to the embodiment of the present invention. Such as figure 1 As shown, in the display panel substrate 1 of the embodiment of the present invention, a display area (also referred to as an active area) 11 is provided. Outside the display area 11, a panel frame area 12 is provided around the display area 11.

[0058] figure 2 It is a plan view schematically showing the structure of pixels, wirings, and the like provided in the display area 11. Such as figure 2 As shown, a plurality of pixels are arranged in a matrix in the display area 11. Each pixel ...

Abstract

Provided are a substrate for a display panel, wherein short-circuiting between wiring electrode terminals can be eliminated, and a display panel. The substrate for a display panel is provided with: a wiring electrode terminal (121) for connecting an external wiring board; an extraction wiring line (122) which is electrically connected to the wiring electrode terminal (121); an interlayer insulating film (209) which covers the extraction wiring line (122); a conductive material film (210) which is formed by being superimposed on the wiring electrode terminal (121) and is electrically connected to the wiring electrode terminal (121); and a conductive material film (211) which is formed by being superimposed on the extraction wiring line (122) with the interlayer insulating film (209) therebetween and is electrically connected to the extraction wiring line (122). The conductive material film (210) formed by being superimposed on the wiring electrode terminal (121) and the conductive material film (211) formed by being superimposed on the extraction wiring line (122) with the interlayer insulating film (209) therebetween are separated from each other at the periphery of the interlayer insulating film (209).

Description

Technical field [0001] The present invention relates to a substrate for a display panel and a display panel, and more particularly to a terminal (specifically, for example, a strip-shaped pad) for electrical connection with TCP (Tape Carrier Package) or the like is provided on the periphery A substrate for a display panel and a display panel provided with the substrate for a display panel. Background technique [0002] A general liquid crystal display panel includes two substrates. For example, an active matrix type liquid crystal display panel includes a TFT array substrate and a counter substrate (as the counter substrate, for example, a color filter can be applied). In addition, these substrates are relatively bonded with a predetermined minute interval, and liquid crystal is filled between these substrates. [0003] The surface of the TFT array substrate is provided with a display area (also called an active area) and a panel frame area surrounding the display area. In the d...
