Problems solved by technology

For example, annealing process, etching process, etc. can cause damage to the material of signal wiring
Thus, even when the signal wiring includes a low-resistance material known in the art, when the low-resistance material is directly used as a conductive pattern, it is often difficult to ensure process reliability.

Abstract

The invention discloses a conductive pattern, a display device including the same, and a method of manufacturing the conductive pattern. The conductive pattern of a display device includes: a first layer disposed on a substrate, including aluminum or an aluminum alloy, and forming a first taper angle with the substrate; and a second layer disposed on the first layer and forming a second taper angle with the first layer, wherein the second taper angle is less than the first taper angle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to, and the benefit of, Korean Patent Application No. 10-2017-0160172 filed on Nov. 28, 2017, which is hereby incorporated by reference for all purposes as if fully set forth herein Explain the same. technical field [0003] Exemplary embodiments of the present invention generally relate to a conductive pattern, a display device including the conductive pattern, and a method of manufacturing the conductive pattern. Background technique [0004] Electronic devices typically employ conductive patterns such as wires or electrodes to transmit signals. For example, a display device such as an organic light emitting display device or a liquid crystal display device may include a plurality of conductive patterns for driving thin film transistors (TFTs). However, when the length of the signal wiring increases, signal delay may occur due to the internal resistance of the signal wiring. Since ...
