Domain-divided twisted nematic liquid crystal cell and method of fabricating thereof having a differentially removed photosensitive layer
A domain-divided twisted nematic crystal cell and method of fabricating thereof. The method of the present invention comprises the steps of providing first and second substrates, forming a photo-alignment layer in each domain of the first substrate having two or more domains, wherein thicknesses of the photo-alignment layers corresponding to the domains are different from each other. A pretilt angle in each domain is formed by light irradiation on the photo-alignment layer, wherein the pretilt angles corresponding to the domains are different from each other due to the different thicknesses of the photo-alignment layer in different domains. The first and second substrates are positioned to face each other, and liquid crystal is injected between the first and second substrates.
