Thin film transistor array substrate having laser illumination indicator

摘要

A thin film transistor array substrate includes an insulating substrate, and gate lines formed on the substrate, storage electrode lines and storage electrodes are also formed on the substrate. Data lines cross over the gate lines and the storage electrode lines. The data lines are electrically insulated from the gate lines and the storage electrode lines. Thin film transistors are connected to the data lines and the gate lines, and pixel electrodes are connected to the thin film transistors. Bridges are formed at the same plane as the pixel electrodes while interconnecting the storage electrode lines and the storage electrodes placed at both sides of the gate lines. The storage electrode lines and the storage electrodes have protrusions or grooves placed close to the bridges to indicate the locations of laser illumination.
