Patent ID: 8169428

Claim:
A display device comprising: a first substrate; and a second substrate combined with the first substrate to face the first substrate, the second substrate comprising: a signal-applying module disposed on a substrate and having an output terminal configured to output a data signal; a patterned insulation layer having a contact hole that exposes the output terminal; a single layer silver-molybdenum alloy electrode as a reflective electrode, comprising silver and molybdenum, that both reflects light and receives the data signal through the output terminal to change arrangement of liquid crystal molecules interposed between the first and second substrates; and a transparent and conductive electrode formed between the patterned insulation layer and the single layer silver-molybdenum alloy electrode, wherein the single layer silver-molybdenum alloy electrode avoids hillocks and galvanic corrosion between the reflective electrode and the transparent and conductive electrode.
