To reduce the manufacturing cost of a TFD element-driven reflection and reflection/semitransmission type liquid crystal display device using an MIM type nonlinear element and, at the same time, to improve the refinement and contrast of the device by proposing a new manufacturing process.
The manufacturing cost of an MIM type nonlinear element is reduced by improving the throughput and yield by reducing the number of manufacturing processes of the element. Specifically, the manufacturing process is shortened and, accordingly, the manufacturing cost is reduced by anodically oxidizing a first metal 1 through a transparent electrode film 2 in an anodic oxidation step. When the electrode film 2 is utilized as a base film, Ag and an AG alloy can be used as the raw material of wiring and reflective electrodes and the refinement and contrast of the element can be improved.
