摘要： A liquid crystal display device with an IPS mode having wide view angle characteristic and capable of improving response time and transmittance, is disclosed. A liquid crystal display device with an in-plane switching mode includes a first substrate having first and second electrodes formed thereon. A second substrate is disposed opposite to the first substrate with a selected distance. On a surface of the second substrate are also formed third and fourth electrodes. When a voltage is applied to the respective electrodes, a first electric field which is parallel to the planes of the substrates is generated between the first electrode and the second electrode, and a second electric field which is parallel to the planes of the substrates and is orthogonal to the first electric field is generated between the third electrode and the fourth electrode. A polarizer is arranged on the outside of the first substrate and a analyzer is arranged on the outside of the second substrate. A first homogeneous alignment film is applied to the first substrate on which the first and second electrodes are formed. A second homogeneous alignment film is also applied to the second substrate on which the third and fourth electrodes are formed. A liquid crystal layer having liquid crystal molecules is interposed between the both substrates, wherein the liquid crystal molecules are arranged in a homogeneous state in an absence of the electric field and are twisted in a presence of the electric field.

摘要： A polymer dispersed liquid crystal display device is disclosed. A polymer dispersed liquid crystal display device of the present invention includes a pair of substrates inside which electrodes are formed, respectively. The substrates are disposed to be opposite to each other and to be spaced to a cell gap. A liquid crystal polymer network and liquid crystal droplets which are phase separated from each other, are interposed between the substrates. The liquid crystal polymer network is perpendicularly arranged to the planes of the substrates regardless of presence or absence of electrical field. The liquid crystal droplets includes a plurality of liquid crystal molecules and are dispersed in the liquid crystal polymer network. The liquid crystal polymer network has a birefringe index which is similar to that of the liquid crystal. The liquid crystal polymer network is that a liquid crystal polymer having a higher glass transition temperature than an operation temperature of the liquid crystal is perpendicularly arranged to the planes of the substrate by a voltage of 1 to 100 V and hardened as it is. Preferably, the liquid crystal polymer network is that a liquid crystal monomer having UV hardening property is perpendicularly arranged to the planes of the substrates and harden as it is.
