In a liquid crystal display device in which a plurality of liquid crystal layers are stacked on a substrate, a method for bonding a film for sealing liquid crystal to supporting members is improved and the fabrication cost is thereby reduced, in order to provide a reflective type liquid crystal display device that achieves a bright display image and causes no parallax problem, and to provide a reducing method of the device. The liquid crystal display device comprises a substrate, a resin film, a multiplicity of columnar supporting members, an adhesive layer, and a liquid crystal layer. The substrate comprises a pixel electrode and a driving element connected to the pixel electrode, both formed on the upper surface of the substrate. The resin film comprises a common electrode provided on the upper surface of the film, and is disposed upwardly with respect to the substrate. The supporting members are provided on the substrate so as to support the resin film. The adhesive layer is provided between each of the supporting members and the resin film so as to bond the resin film to each of the supporting members. The liquid crystal layer is produced by filling liquid crystal between the substrate and the resin film. The adhesive layer is composed of a thermoplastic material, and characterized in that a bonding state of the resin film and the supporting members is realized by making the adhesive layer have a thermoplastic characteristic.

Liquid crystal display device including a stack of plurality of resin film and method for fabricating the same

A liquid crystal display device having a pixel electrode, a counter electrode, and a liquid crystal between the electrodes. Liquid crystal molecules in contact or near the respective opposed surfaces of the electrodes have specified pretilt angles as a result of the conditioning of those surfaces. When no voltage is applied, the liquid crystal is in a splay alignment state; applying voltage prior to image display causes a transition of transformation of the splay alignment state to a bend alignment state; image display is carried out under the bend alignment state. Transition from the splay alignment state to the bend alignment state is promoted by having a large pretilt angle domain formed on at least one of the electrode surfaces causing a larger pretilt angle of liquid crystal molecules than is present in a region surrounding the large pretilt angle domain.

Liquid crystal display device and associated fabrication method

Liquid crystal display device and method of manufacturing the same

A liquid crystal display comprises as liquid crystal panel having a liquid crystal layer disposed between electrode layers, polarizers disposed at both sides of the panel, and a solid birefringent film having the maximum refractive index direction varying with its depth and disposed at at least one side of the liquid crystal panel between the polarizers. The solid birefringent film conpensates the dependence of the polarization characteristic on wave length, thus being capable of obtaining either a monochrome display or a display having an extremely low coloration.

Liquid crystal matrix display unit

A method of producing a substrate structure for a large size display panel. The method involves conveying a transparent substrate from a transparent substrate storage means in a conveying path through a vacuum chamber, and while conveying the substrate, forming at least a patterned transparent conductive film on a surface of the substrate by depositing strips of conductive film on the substrate through a pattern containing member extending in a direction orthogonal to the substrate conveying direction and having strip forming openings therein at intervals along the lengths thereof, and storing the transparent substrates with the strips thereon at the end of the conveying path.

To obtain low insertion loss and low TTE level, a first central transducer, a second transducer and a third transducer are disposed on one surface of a piezoelectric substrate in such a manner that the second and the third transducers are in the direction of propagation (X-direction) of surface acoustic waves launched by the first transducer and the distance between center lines of the first and the second transducers and also the distance between the center lines of the first and the third transducers vary along the Y-direction perpendicular to the X-direction.

Due to the provision of the intermediate layer, the brightness of the electroluminescent panel can be kept high for a long time.
