A display medium includes a first substrate that is transparent to light, a second substrate, a spacing member, and a particle dispersion liquid. The second substrate is provided to be opposite to the first substrate and has a plurality of electrodes placed at a predetermined interval. The spacing member (i) is placed between the first and second substrates at another interval different from the predetermined interval of the electrodes, (ii) has a first end portion on a first substrate side of the spacing member and a second end portion on a second substrate side of the spacing member. The first end portion is transparent to light. The second end portion has different transparency from the first end portion to reduces a reflection of light incident through the first substrate onto a first substrate side of the spacing member.

Display medium and display device

A display medium of the present invention includes first and second substrates, a spacing member and a particle dispersion liquid. The first substrate is transparent to light. The second substrate is opposite to the first substrate and has plural electrodes placed at an interval. The second substrate has a difference between reflectivity of the electrode portions and reflectivity of plural boundary portions between the electrodes with respect to light incident from the first substrate side. The difference is 12 percentage points or less. The spacing member is placed between the first and second substrates at another interval, is transparent to light, and keeps a gap between the first and second substrates. The particle dispersion liquid is filled between the first and second substrates, and includes particles moving in a direction of an electric field formed between the first and second substrates and a dispersion medium.

The present invention provides a method of manufacturing a display medium, including preparing a first substrate on which a gap retaining member that retains a gap between substrates is disposed in a protruded form; applying an adhesive to a top surface of the gap retaining member; disposing a particle dispersion liquid on an area surrounded by the first substrate and the gap retaining member; and adhering the first substrate and a second substrate together via the gap retaining member, by contacting the second substrate with the adhesive applied to the top surface of the gap retaining member and drying the solvent of the adhesive so as to adhere the second substrate to the top surface of the gap retaining member by the adhesive component of the adhesive. The display medium and a display apparatus including the display medium and an electrical field-generating unit are also provided.

Method of manufacturing display medium, display medium, and display apparatus

The present invention provides a display medium which prevents a decrease in reflectance during storage at high temperatures, and a writing apparatus using the display medium. A photoconductive layer, a selective light transmission layer, and a liquid crystal layerare laminated between substratesand, which have electrodesand, respectively, to form a display medium. The selective light transmission layeras a color layer is composed of a deionized material. The ion concentration of the selective light transmission layeris controlled to be within a predetermined range.

Display medium and writing apparatus

An image record apparatus for recording a visible image on each of image record mediahas a light application sectionfor applying exposure light to the plurality of placed image record media, a voltage application sectionfor applying an image write voltage to each of the plurality of placed image record media, and a control sectionfor controlling the light application sectionand the voltage application sectionso that exposure light for representing a visible image is applied to the plurality of placed image record media and the image write voltage is applied to the image record mediumon which the same visible image as the image is to be recorded.

Image record medium and image record apparatus

A display medium includes: a pair of substrates that have light transmittance; electrode members that are respectively formed on the opposing surfaces of the substrates, have light transmittance, and are capable of carrying an electric current; a display member that is interposed between the electrode members and displays display information when the electric current is supplied; a terminal portion provided at one electrode member; a reinforcing portion that has electrical conductivity and is joined to the terminal portion; and a mounted electrode that has electrical conductivity and is joined to the terminal portion by a joining material that has, after curing, a cohesive force larger than that of the reinforcing portion. The area of a reinforcing joining region of the terminal portion to which the reinforcing portion is joined is smaller than the area of a mounted joining region of the terminal portion to which the joining material is joined.

Display medium

An optically writable display medium includes an optical switching element and a display element. The optical switching element includes a charge transport layer sandwiched between an upper charge generating layer and a lower charge generating layer. The display element includes a display layer having memory properties and is provided on the optical switching element. The absorption wavelength region of the upper charge generating layer and the absorption wavelength region of the lower charge generating layer are substantially different from each other.

Optically writable display medium and optical writing method

An optical write apparatus has an image display screenfor displaying an image and role switch sectionfor switching the image display screenbetween a role in displaying an image for observation and that in writing an image onto an image record mediumonto which an image is written upon application of light for representing the image.

Optical write apparatus and optical write method

An input-output unit includes a display unit having a bendable display screen for displaying information on the bendable display screen; and a pressure-sensitive input unit containing detection means being provided below the display screen for detecting a position on the bendable display screen in response to press pressure from a view side of the bendable display screen.

To assure that a plate-shaped brittle material is exactly cut into two plate pieces, a jig having a thread-shaped projection secured thereto in conformity with a predetermined pattern positionally coincident with a cut groove formed in the plate-shaped brittle material, an elastic member located on the cut groove side of the plate-shaped brittle material, and a plate-shaped brittle material to be cut into two plate pieces are placed on a table of a press machine one above another, and subsequently, a predetermined intensity of pressing power is applied to the jig from above by operating a pressing machine. Alternatively, a jig having a thread-shaped projection secured thereto, an elastic member located on the opposite side relative to the cut groove side of the plate-shaped brittle material, and a plate-shaped brittle material to be cut into two plate pieces may be placed on the press table one above another. Otherwise, a pair of jigs each having a thread-shaped projection secured thereto, a pair of elastic members one of which is located on the cut groove side of a plate-shaped brittle material and other one of which is located on the opposite side relative to the cue groove side of the plate-shaped brittle material, and a plate-shaped brittle material to be cut into two plate pieces may be placed on the press table one above another.
