Field
The disclosed technology relates to display substrates having electronic devices and wiring structures and related manufacturing methods.
Description of the Related Technology
As for a flat panel display, for example, an organic light emitting diode (OLED) device or a liquid crystal display (LCD) display panel, a light emitting structure including an organic light emitting layer or a liquid crystal layer is formed on a display substrate.
The display substrate includes many switching devices known as thin film transistors (TFTs), capacitors and wiring structures such as data and gate lines. A current and an electrical signal are applied through the wiring structure. However, as the resistance of the wiring structure increases, imaging characteristics of the display degraded due to, for example, signal delays. More particularly, as the resolution of the display increases, the width and/or thickness of the wiring structure decrease to result in a higher overall resistance of the wiring structure.
