Abstract

The invention relates to a circuit structure for repair and a flat panel display device with the circuit structure. A line structure for repair may include: a first line positioned in a first direction; a second line parallel to the first line, the second line having side portions extending from corresponding ends along the second direction and connected to the first line; and a third line crossing the first line and the second line, wherein at least a portion of the second line is made of undoped polysilicon.

Description

[0001] Cross references to related patent applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2013-0027563 filed with the Korean Intellectual Property Office on March 14, 2013, the entire contents of which are hereby incorporated by reference in their entirety. technical field [0003] Embodiments of the present invention relate to a wiring structure and a flat panel display device having such a wiring structure. Background technique [0004] Generally, a flat panel display device such as a liquid crystal display (LCD), a plasma display panel (PDP), or an organic light emitting display (OLED) is manufactured through a semiconductor device manufacturing process. In the semiconductor device manufacturing process, lines connecting thin film transistors, capacitors, and circuits are formed into patterns with extremely small widths and intervals, and the patterns are arranged in a multilayer structure with an interlayer insulat...
