Problems solved by technology

[0003] In addition, in a liquid crystal display panel, as pixels become more precise, the intervals between gate lines, source lines, and capacitor lines provided on an active matrix substrate become narrower. Therefore, for example, When manufacturing an active matrix substrate, foreign substances called particles adhere to the surface of the substrate, and as a result, each wiring is short-circuited, TFT characteristics become poor, and there is a high possibility of defects occurring in pixels

Abstract

An active matrix substrate includes a plurality of first interconnections (1a) which are extended parallel to each other, a plurality of second interconnections (1b) which are interposed between the first interconnections (1a) and extended parallel to each other, and a third interconnection (3c) which intersects the first interconnections (1a) with an insulation film interposed therebetween is connected to the second interconnections (1b) via a contact hole (11a) formed in the insulation film, and is wider than the second interconnections (1b). Each of the first interconnections (1a) has a dual-line portion (Wa) and a single-line portion (Wb) which are connected to each other in a portion below the third interconnection (3c). The dual-line portion (Wa) and the single-line portion (Wb) are so arranged as to be adjacent to each other. In the third interconnection (3c), a slit (Sa) is so formed as to intersect the dual-line portions (Wa). The contact hole (11a) is formed between adjacent single-line portions (Wb).

Description

technical field [0001] The present invention relates to an active matrix substrate, a liquid crystal display panel equipped with the same and a manufacturing method of the active matrix substrate, in particular to a defect correction technology of the active matrix substrate and the liquid crystal display panel equipped with the same. Background technique [0002] In a liquid crystal display panel having an active matrix substrate, for example, thin film transistors (hereinafter referred to as "TFTs") are respectively provided in pixels, which are the smallest units of an image, and each pixel can be reliably turned on and off by each TFT, thereby enabling Fine dynamic image display, so it is widely used. [0003] In addition, in a liquid crystal display panel, as pixels become more precise, the intervals between gate lines, source lines, and capacitor lines provided on an active matrix substrate become narrower. Therefore, for example, When manufacturing an active matrix s...
