Abstract
The invention provides an LCD device, whose polarizers comprising: a plurality of polarizing units disposed corresponding to the first, second and third sub-pixels and arranged in an array; each polarizing unit being a multilayer film structure, comprising a transparent body, and a plurality of first film layers and a plurality of second film layers interleaved into a stack disposed on the body. By achieving polarization through multilayer film structure and each polarizing unit only needing to satisfy polarization conditions for light of the wavelength range of light emitted by corresponding sub-pixel, the invention can reduce material selection difficulty and production difficult for multilayer structure and improve LCD contrast.
