Abstract
Some conventional liquid crystal display devices were hard to make connection to a pixel electrode interposed between liquid crystal layers when a picture element is configured by laminating a plurality of liquid crystal layers. The liquid crystal display device comprises a first substrate having a first applying means for applying a first signal; a first electrode opposed to the first substrate; at least one liquid crystal layer interposed between the first substrate and the first electrode; a pillar made of an insulating material, formed on the first substrate so as to have a lateral face and to pierce through the liquid crystal layers; and at least one first wiring pattern formed on the lateral face of the pillar to connect the first applying means and the first electrode. Specifically, this liquid crystal display device has the pillar and the wiring pattern formed on the lateral face of the pillar as the inter-connector to connect to the pixel electrode interposed between the liquid crystal layers. The pillar may be formed into, for example, a truncated pyramid shape, and its top face can be used to connect the pixel electrode with the wiring pattern.
