Abstract
An IPS LCD (100) includes a first and a second substrates (110, 120) opposite to each other, and a liquid crystal layer (130) sandwiched therebetween. A first polarizer (111) is disposed at an outer surface of the first substrate, and a second polarizer (121) is disposed at an outer surface of the second substrate. Polarizing axes of the first and second polarizers are parallel to each other. A plurality of pixel electrodes (160) and common electrodes (170) are disposed at the second substrate. A first alignment layer (114) is disposed at an inner surface of the first substrate, and a second alignment layer (124) is disposed at an inner surface of the second substrate. The first alignment layer maintains a rubbing direction of approximately 90° relative to the second alignment layer, and the second alignment layer has an anchoring strength greater than that of the first alignment layer.
