Abstract: A liquid crystal device having a pair of substrates opposed to each other at a predetermined distance from each other, and a liquid crystal enclosed between the pair of substrates. The pair of substrates are formed of different materials, and the difference between the thermal expansion coefficients of the substrates is set within the range of .+-.50% of the thermal expansion coefficient of one of the two substrates. Misalignment between the substrates is thereby prevented.

Abstract: A photosensor includes a substrate; a photoconductive layer formed on the substrate; a pair of electrodes mounted on and electrically connected to the photoconductive layer; a light reception portion formed between the electrodes; and a protective layer formed on the light reception portion; wherein an organic silicon film with a small content of metal ion is formed at least at the uppermost portion of the protective layer.

Abstract: In fabricating a liquid crystal panel, preparing a substrate sized larger than the same at a finished state, following to bonding the prepared substrate, an excess peripheral portion of the substrate is cut off. A dummy seal having an opening portion at least in part thereof is formed on the excess portion of the substrate. And, the opening portion of the dummy seal is sealed off to make the dicing after bonding of upper and lower substrates and curing of the seal.

Abstract: A method of producing a photosensor having a photoconductive layer and a pair of electrodes provided through an ohmic contact layer on the same surface of the photoconductive layer for applying a voltage to the photoconductive layer. The method comprises the steps of: forming an insulating layer on one surface of the photoconductive layer except at portions where the pair of electrodes is to be formed; forming a layer of an ohmic contact layer forming material on the insulating layer; forming a layer of an electrode forming material on the layer of an ohmic contact layer forming material; and removing the electrode forming material except at the portions where the pair of electrodes is to be formed, and the ohmic contact layer forming material.

Abstract: A photosensor comprises a glass substrate, a photoelectric converting layer comprising a silicon-based amorphous material, and a pair of electrode layers in electrical contact with the photoelectric converting layer, wherein one or both sides of the glass substrate are covered with dielectric layers and the photoelectric converting layer is formed upon the dielectric layer.

Abstract: A photosensor array comprises a substrate, a photoconductive layer and electrode layers between which the photoconductive layer is provided, wherein an opaque electroconductive layer is provided at a side opposite to a side to which a signal light is projected, and an insulating layer intervenes between the opaque electroconductive layer and the combination of the electrodes and the photoconductive layer. In a photosensor array of a matrix driving type using a multilayer wiring, an insulating layer between electrodes at the multilayer wiring portion and a protective insulating layer at a photoelectric transducer portion are continuously formed by using the same material.

Abstract: A method for preparing a photosensor having electrodes formed on a photoconductive layer through an intermediary ohmic contact layer is provided which comprises forming an ohmic contact layer on a photoconductive layer, forming electrodes with a desired shape on the ohmic contact layer, then removing the ohmic contact layer at the exposed portion for photoelectric transducing by the etching method and thereafter applying heat treatment, thereby forming a photosensor array.
