Abstract:
A transflective liquid crystal display device provided with columnar spacers is provided that can suppress variation in color tone of white in a reflective mode and can minimize degradation in reflectivity even when a coloring material used for a transmissive region and a coloring material used for a reflective region are the same. The device includes a color filter substrate, a TFT substrate, a liquid crystal material sandwiched by the color filter substrate and the TFT substrate, columnar spacers formed only in pixels having a green coloring material and defining a cell gap, and light-blocking portions provided only in predetermined regions in the vicinity of locations where the columnar spacers are formed.

A liquid crystal display device includes a gate line placed on an array substrate, a pixel electrode in a comb teeth shape, a common electrode in a comb teeth shape that generates an in-plane electric field with the pixel electrode, an alignment layer that has an alignment direction inclined at a predetermined rubbing angle β with respect to a vertical direction perpendicular to the gate line, and two sections (upper pixel and lower pixel) where a direction of response of liquid crystals is different. The comb teeth of the pixel electrode and the common electrode are inclined at a predetermined electrode angle α with respect to the vertical direction in each of the two sections, and the electrode angle α and the rubbing angle β satisfy conditions of |α|>|β| and 90°−|α−β|≧45° in each of the two sections.

Abstract:
In a liquid crystal displaying device where the aperture ratio is made higher by using a photocuring adhesive sealant for adhering two substrates, and the contraction of tact time is achieved, a liquid crystal displaying device which is free from inferior curing of the adhesive sealant and is high in reliability can be obtained. In two substrates for forming a liquid crystal displaying device, where the substrates have at least one layer of light shielding film, the inferior curing of the photocuring adhesive sealant can be removed by limiting the width of the light shielding film existing above or under the adhesive sealant which glues the two substrates. As this result, a liquid crystal displaying device which is high in aperture ratio and high in reliability can be obtained.
Abstract:
The present invention discloses a liquid crystal display apparatus including (1) a liquid crystal panel including an electrodes substrate provided with pixel electrodes and counter electrodes, a counter substrate which opposes the electrodes substrate, and a liquid crystal layer containing therein liquid crystal molecules which are driven by an electric field that is generated in a substantially parallel manner with respect to a surface of the electrodes substrate when voltage is applied on the pixel electrodes and counter electrodes; and (2) a driving circuit for supplying predetermined electric signals to the pixel electrodes and the counter electrodes, wherein inclining directions of liquid crystal molecules which are closest to the electrodes substrate and those of liquid crystal molecules which are closest to the counter substrate are identical, and aligning directions of liquid crystal molecules which are closest to the electrodes substrate and those of liquid crystal molecules which are closest to the counter substrate are parallel to each other.
Abstract:
Provided is an in-plane response-type liquid-crystal display device having a sufficiently high contrast ratio enough to display high-quality images. The device is free from the problem of light leak to be caused by spacers, and is free from the problem of rough surface appearances. In the device, the surface of each spacer is coated with a thermoplastic polymer prepared through graft polymerization of a molecular compound having a vinyl group or a polymerization initiator, with one or more polymerizable monomers. The functional groups existing in the surface of each spacer are bonded to the alignment layers adjacent to the spacers via van der Waals bonding or hydrogen bonding, whereby the spacers are fixed onto the orientation film on at least one of the electrode substrate and the color filter substrate constituting the device. The bonds are extremely small, and the region around the spacers through which light will leak is much reduced. In addition, the spacers are prevented from moving to scratch the neighboring alignment layers, and light leak through the device is prevented. The spacers preferably have a number of long-chain alkyl groups each having at least 6 carbon atoms in their surfaces, and light leak around the spacers is well prevented.
