LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD OF THE SAME

摘要

The present disclosure relates to a liquid crystal display device having a protection element for semiconductor layer from externally intruding light and a manufacturing method of the same. The present disclosure suggests a liquid crystal display device comprising a substrate; a data line and a gate line crossing each other on the substrate; a thin film transistor formed at a crossing portion of the data line and the gate line; a passivation layer covering the thin film transistor; and an opaque protective layer forming on the passivation layer and covering the thin film transistor. The liquid crystal display device according to the present disclosure blocks the light intrusion into the semiconductor active layer of the thin film transistor to enhance the electron mobility in the active layer and the reliability of the elements.
