Abstract:
A liquid crystal display device comprising:a first substrate having a first applying means for applying a first signal and a second applying means for applying a second signal;a first electrode opposed to the first substrate;a second electrode interposed between the first substrate and the first electrode, the second electrode being overlapped with the first electrode;a first liquid crystal layer interposed between the first electrode and the second electrode;a second liquid crystal layer interposed between the second electrode and the first substrate;a pillar formed on the first substrate so as to pierce through the first and the second liquid crystal layers, the pillar being formed of an insulating material, and the pillar having a top face and a lateral face; anda first and a second wiring patterns formed around a lateral face of the pillar, the first wiring pattern connecting the first applying means to the first electrode, and the second wiring pattern connecting the second applying means to the second electrode;wherein the first liquid crystal layer comprises microcapsules containing a first liquid crystal material,wherein the second liquid crystal layer comprises microcapsules containing a second liquid crystal material,wherein the first wiring pattern is formed extendingly to the top face of the pillar, and the first wiring pattern is connected with the first electrode on the top face of the pillar, andwherein the second wiring pattern has a first portion and a second portion, the first portion is formed from the second applying means to the top face of the pillar, the second portion is formed from the top face of the pillar to the second electrode, and the first portion and the second portion of the second wiring pattern are connected at the top face of the pillar.
