LIQUID CRYSTAL PANEL WITH BUILT-IN DRIVER AND PRODUCTION THEREOF

摘要

PURPOSE:To produce a liq. crystal display panel with a built-in driver capable of fitting to fine division of a picture element region. CONSTITUTION:The circuit layers 19-21 of a driving circuit on a transparent substrate 9 has three-layered circuit structure and each pitch is narrow. The 1st layer 19 is an impurity doped polycrystalline Si layer formed simultaneously with the gate 5 of TFT 8, the 2nd layer 20 is a Cr layer formed simultaneously with a 1st data line 14 and the 3rd layer 21 is an Al layer formed simultaneously with a 2nd data line 15. The 1st data line 14 and the 2nd data line 15 form a data line 2a having double redundant circuit structure.
