Reflection-type liquid crystal display having a silver or silver alloy upper electrode layer
 A reflection-type liquid crystal display device includes a first substrate including a plurality of pixel electrodes arranged in a matrix and switching devices for driving the pixel electrodes. A second substrate includes a counter electrode, and a liquid crystal layer is interposed between the first substrate and the second substrate. The pixel electrodes each include a lower electrode layer and an upper electrode layer. The upper electrode layer is formed of either silver or a silver alloy and is reflective.
