Problems solved by technology

In simplifying the entire manufacturing process of display devices, the process for forming the ohmic contact layer becomes a limitation
[0004] In addition, since capacitors generally include at least one metal electrode, it is not easy to increase the aperture ratio of the display device

Abstract

A display device according to an exemplary embodiment includes: gate wires, at least one of the gate wires having a first multi-layered structure including a first transparent conductive layer formed on the substrate and a first metal layer formed on the first transparent conductive layer and at least another one of the gate wires having a first single-layered structure formed with the first transparent conductive layer; a semiconductor layer formed on a part of the gate wires; and data wires with at least one of the data wires having a second multi-layered structure including a second transparent conductive layer formed on the semiconductor layer and a second metal layer formed on the second transparent conductive layer and at least another one of the data wires having a second single-layered structure formed with the second transparent conductive layer.

Description

technical field [0001] Exemplary embodiments of the described technology relate to display devices and methods of manufacturing the same. More specifically, the described technology relates to a display device and a method of manufacturing the same while simplifying its structure while increasing its aperture ratio. Background technique [0002] Most flat panel display devices, such as organic light emitting diode (OLED) displays, liquid crystal displays (LCD), etc., include thin film transistors and capacitors. [0003] A thin film transistor includes an ohmic contact layer formed to reduce contact resistance between a semiconductor layer and source and drain electrodes. The ohmic contact layer is often formed by doping the semiconductor layer with impurities. In simplifying the entire manufacturing process of a display device, a process for forming an ohmic contact layer becomes a limitation. [0004] In addition, since the capacitor generally includes at least one meta...
