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. |
