The present invention relates to a liquid crystal display device, comprising: a first substrate with a first alignment layer disposed thereon; a second substrate with a second alignment layer disposed thereon; and a liquid crystal layer, comprising a negative liquid crystal composition and interposed between the first substrate and the second substrate, wherein the first alignment layer and the second alignment layer are disposed opposite to each other. In the present invention, at least one of the first alignment layer and the second alignment layer has a volume resistivity of 1.5×1012 to 9×1015 Ω·cm, at least one of the first alignment layer and the second alignment layer absorbs a light having a wavelength of 240 nm to 400 nm, or a surface of at least one of the first alignment layer and the second alignment layer includes a plurality of protrusions formed by polymerizing a uv reactive monomer..

Illumination device for a liquid crystal display


The invention relates to an illumination device for illuminating at least one light modulator system of a liquid crystal display, the device comprising at least one waveguide substrate for guiding at least one targeted light beam that can be coupled into the waveguide substrate. The waveguide substrate is at least in optical contact with at least one holographic optical decoupling substrate comprising a plurality of decoupling regions and a decoupling region is at least designed to decouple part of the targeted light beam in the form of a plurality of sub-beams in the direction of the light modulator system.

Display having backlight with narrowband collimated light sources


A display has an array of display pixels formed from display layers such as one or more polarizer layers, a substrate on which an array of display pixel elements such as color filter elements and downconverter elements are formed, a liquid crystal layer, and a thin-film transistor layer that includes display pixel electrodes and display pixel thin-film transistors for driving control signals onto the display pixel electrodes to modulate light passing through the display pixels. A light source such as one or more laser diodes or light-emitting diodes may be used to generate light for the display.

Optical element


An optical element and a use of the optical element are provided. The exemplary optical element can be useful in realizing a smart blind having excellent transmission and blocking characteristics in front and lateral surfaces thereof without using a retardation film by employing a polarizing layer whose polarization characteristics are patterned using a guest/host-type dye layer including a polymerizable liquid crystal compound and a dichroic dye.
