摘要:
A display having high re-workability, a method for producing the display, and a transparent resin filler, are provided. A transparent resin filler (5), in which a value obtained on multiplying a hardness of an as-cured resin, expressed as Shore E, with a bonding strength, is not greater than 400, is used as a material of a transparent resin layer (4) to be charged between a picture image display panel (2) and a front side panel (3). In case an undesirable situation, such as mixing of foreign matter in the transparent resin layer (4), has occurred, a re-working member may be moved with ease through a space between the picture image display panel (2) and the front side panel (3) to separate picture image display panel (2) and the front side panel (3) from each other.

A thin image display apparatus capable of high luminance and high contrast display of a display part, which does not produce display defects resulting from deformation of the image display part. The thin image display apparatus has an image display part and a light-transmitting protective part arranged on the image display part. A cured resin layer is arranged between the image display part and the protective part. The cured resin layer has a transmittance in the visible region of 90% or higher and a storage modulus at 25° C. of 1.0×107 Pa or less. The cured resin layer is formed from a resin composition which has a curing shrinkage ratio of 5.0% or less.
摘要:
A bonding device for charging a liquid material into a space between plate-shaped members for bonding them together in situ, in which the liquid material may be prevented from exuding from the space between the plate-shaped members. The bonding device includes pair retaining base members for retaining the pair plate-shaped members facing each other, and a retaining base member movement unit for causing movement of the retaining base members towards and away from each other. The bonding device also includes an illumination unit that illuminates curing light to a photo-curable liquid material charged between the pair plate-shaped members held by the pair retaining base members, and a sensor that detects the wetting spreading state of the liquid material charged between the pair plate-shaped members.

An epoxy resin composition containing an epoxy resin and a thermal cationic polymerization initiator not only can reduce the amount of fluorine ions generated during thermal cationic polymerization to improve electrolytic corrosion resistance but also is excellent in low-temperature rapid curability. The epoxy resin composition uses a sulfonium borate complex represented by the formula (1) as the thermal cationic polymerization initiator. In the formula (1), R1 is an aralkyl group, and R2 is a lower alkyl group, provided that when R2 is a methyl group, R1 is not a benzyl group. X is a halogen atom, and n is an integer of 1 to 3.
摘要:
The present invention prevents air bubbles from being mixed in at the time of resin filling. In a supplying step (FIGS. 5D, 5E), a transparent resin filler is dispensed and supplied from supply means so that the transparent resin filler comes into contact with both of an image display panel and a front panel to draw a predetermined pattern, and the transparent resin filler is maintained in contact with both of the panels until drawing of the predetermined pattern is completed.

An image display device has an image display part and a protective part on the image display part. The image display device suppresses image unevenness and cured resin peeling caused by internal stress generated due to curing shrinkage of a cured resin between the protective part and the image display part or external stress applied on the image display part due to warping of the protective part. A cured resin layer is arranged between the image display part and the protective part. The cured resin layer has a light transmittance in the visible region of 90% or more, an elongation ratio of 700% or more at 25° C. and 400% or more at 80° C., and an adhesive force with respect to the protective part of 0.4 N/cm or more at 25° C. and 0.3 N/cm or more at 80° C.

In an apparatus for charging and coating a liquid material into a gap between plate-shaped members with an emission nozzle, damages to the plate-shaped members by contact with the emission nozzle, drooping of the liquid material or a decreased coating speed is to be prevented. To this end, the apparatus includes a plurality of holding members (4, 5) for holding a plurality of plate-shaped members (2, 3) so that the major surfaces of the plate-shaped members (2, 3) will face each other, and a movement member (6) for causing movement of the holding members (4, 5) towards and away from each other. The apparatus also includes an emission nozzle (10) introduced into a gap defined between the plate-shaped members (2, 3), held for facing each other, to emit a charging liquid material (7) into the gap. The apparatus also includes a nozzle movement unit (11) for causing movement of the emission nozzle (10) in an in-plane direction of the plate-shaped members (2, 3), and a control unit (21) for controlling the nozzle movement unit (11). The apparatus further includes a reservoir (15) for storing the charging liquid material (7) and a thrust unit (13) for emitting the charging liquid material (7) stored in the reservoir (15) via the emission nozzle (10). The emission nozzle (10) is coated with resin.

A method for producing a display device includes: (a) coating a resin composition on at least one of a display part and a protective part, (b) closely adhering the display and protective parts via a resin composition interposed therebetween, and (c) arranging the cured resin layer between the display and protective parts by curing the resin composition by irradiating UV rays on an external side of the protective part. If a defect is detected, the method includes: (d) separating the display and protective parts by applying a wire to a side face of the cured resin layer where the protective and display parts are bonded and moving the wire through the cured resin layer, (e) peeling off and removing the cured resin adhered to the separated display and protective parts by a removing solution which contains an organic solvent, and (f) repeating steps (a) to (c).
