A liquid crystal display device is constructed such that a liquid crystal layer is sandwiched between an upper substrate, which is provided with upper transparent electrodes for forming pixels, and a lower substrate, which is provided with lower transparent electrodes disposed so as to intersect with the upper transparent electrodes. The liquid crystal panel includes a half reflection layer having a reflection function and a transmission function which is formed on the inner surface of the lower substrate as a lower layer of the lower transparent electrodes; an upper retardation film, an upper polarizing plate, and a light diffusing plate which are laminated on the upper substrate; and a lower retardation film and a lower polarizing plate, which are laminated on the surface of the lower substrate. Due to such a construction, the half reflection type liquid crystal display device is capable of providing an image display of high brightness and high contrast.

Half reflection type liquid crystal display device having matched phase of transmitted and reflected light

A liquid crystal display device including a liquid crystal display panel having a first surface for displaying an image and a second surface different from the first surface, and a position information input device provided on a first-surface side of the liquid crystal display panel. The position information input device is made of a first substrate and a second substrate more easily deformable than the first substrate. A transparent insulation film is formed over a surface of the first substrate opposed to the second substrate, a first transparent electrode is provided on the transparent insulation film, and the transparent insulation film is located between the first substrate and the first transparent electrode.

Liquid crystal display device with a touch panel

A liquid crystal display device includes a pair of substrates, a liquid crystal layer sealed between main surfaces of the substrates, a sealing member formed on peripheral portions of opposing main surfaces of a pair of these substrates to fixedly secure the pair of substrates to each other and surround the liquid crystal layer, and a light shielding film formed on one of the peripheral portions of the pair of substrates opposite to the liquid crystal layer without manual application. A region on which the light shielding film is formed is overlapped on a region of the main surface of one of the pair of substrates on which the seal member is formed in a back-to-back relationship, and light shielding film is formed of polyester-based resin to which a black pigment is added.

Liquid crystal display device

A liquid crystal display device has a position information input device over an image-displaying surface of liquid crystal panel. The position information input device is formed by a first substrate and a second substrate more easily deformable than the first substrate. A transparent insulation film is provided over a surface of the first substrate opposed to the second substrate. By providing a first transparent electrode on the transparent insulation film, the flatness of the first transparent electrode is improved and a connection failure of the position information input device is prevented.
