20100170081 | CLAMP DEVICE - A clamp device includes a first clamp head movable but restricted in movement in a perpendicular direction that is at right angles to a travel direction, and serving as a reference side, a second clamp head movable in a direction coming closer to and in a direction farther away from the first clamp head, capable of clamping a workpiece located between the first and second clamp heads, and tiltable and/or slidable in the perpendicular direction, and a drive unit driving the first and second clamp heads. The workpiece is clamped with the first and second clamp heads by moving the first and second clamp heads in a direction coming closer to each other. | 07-08-2010 |

20100178834 | Method for producing display device - A method for producing a display device in which a repair operation can be carried out easily and reliably without damage to a bonding portion caused by a cured resin. The method comprises: (a) coating a resin composition on at least one of the display part and the protective part, (b) closely adhering the display part and the protective part via the resin composition interposed therebetween, and (c) arranging the cured resin layer between the display part and the protective part by curing the resin composition by irradiating UV rays externally side of protective part. The method further comprises, depending on the presence of defects: (d) separating the display part and the protective part by being in contact with a wire having a smaller diameter than a thickness of the cured resin layer to a side face of the cured resin layer where the protective part and the display part are bonded and moving the wire through the cured resin layer, (e) peeling off and removing the cured resin adhered to the separated display part and the protective part by a removing solution which contains an organic solvent, and (f) repeating steps (a) to (c). | 07-15-2010 |
20100210166 | Method for producing display device - A technology for producing a display device for which a repair operation can be carried out easily and reliably without damage to a display part and a protective part. The method includes: (A) a step of coating a resin composition, which is a raw material of the cured resin, on at least one of the display part or the protective part, (B) a step of closely attaching the display part and the protective part via the resin composition, and (C) a step of arranging the cured resin layer between the display part and the protective part by curing the resin composition by irradiating UV rays from external side of the protective part. After the step (B), the method further includes (b | 08-19-2010 |
20120118483 | METHOD FOR PRODUCING DISPLAY DEVICE - 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). | 05-17-2012 |
20140329431 | RESIN COMPOSITION AND DISPLAY UNIT - A display unit that includes an image display part and a light-transmitting protective part arranged on the image display part. A cured resin layer is arranged between the display part and the protective part. The cured resin layer has a transmittance of 90% or higher in the visible range and a storage modulus at 25° C. of 1×10 | 11-06-2014 |

20100320468 | THIN FILM TRANSISTOR SUBSTRATE AND METHOD OF MANUFACTURING THE SAME - In a portion of a gate signal line and a portion of a common signal line, cutouts which are arranged perpendicular to the extending direction of these lines and open to face each other in an opposed manner are formed. A cruciform shape in appearance is formed by combining a gap defined between the gate signal line and the common signal line extending parallel to each other and the cutouts to each other. The cruciform portion formed in this manner is used as an alignment mark in the exposure of a photolithography step of a layer formed later. Due to such a constitution, in manufacturing a thin film transistor substrate, it is possible to realize the highly accurate alignment without forming a pattern only used for alignment. | 12-23-2010 |
