Abstract
The liquid crystal display device comprises a first substrate, a second substrate opposite to the first substrate, a plurality of switching elements formed on a face of the first substrate, which is opposite to the second substrate, a common electrode formed on a face of the second substrate, the face being opposite to the first substrate, a plurality of liquid crystal layers stacked on the second substrate to hold the common electrode between the layers and the second substrate, and arranged between the first and second substrates a plurality of projection electrodes selectively formed on the liquid crystal layers and a plurality of pixel electrode each formed on a corresponding one of the liquid crystal layers. The pixel electrodes respectively formed between a corresponding couple of the liquid crystal layers are connected to a corresponding one of the switching elements formed on the first substrate through one or several of the protrusion electrode/electrodes. The several protrusion electrodes are brought into contact at each of the boundaries of the adjacent liquid crystal layers and connected in cascade.
