20110061803 | MANUFACTURING METHOD OF IMAGE DISPLAY APPARATUS, AND BONDING METHOD OF BASE MATERIAL - An image display apparatus manufacturing method comprises: arranging a bonding material between a pair of base materials acting as a first or second substrate and a frame member, wherein the bonding material includes a main portion extending along the frame member in a closed shape, and a thinner additional portion branching from the main portion as an elongation of a side constituting the main portion; and bonding, as mutually pressing to each other the base materials, the pair of the base materials by the bonding material, by irradiating an electromagnetic wave to the main portion while moving an irradiation position along the bonding material to melt the main portion, and then hardening the melted main portion. Thus, a crack having a possibility of occurrence and widening from the corners of the bonding material can be easily suppressed. | 03-17-2011 |
20110061804 | BONDING METHOD OF BASE MATERIALS, AND MANUFACTURING METHOD OF IMAGE DISPLAY APPARATUS - It arranges a bonding material between a pair of base materials having different heat capacities and in which a difference between thermal expansion coefficients thereof is within 10×10 | 03-17-2011 |
20110061805 | IMAGE DISPLAY APPARATUS MANUFACTURING METHOD - A bonding step of an image display apparatus manufacturing method includes, after bringing a first or second substrate opposite to a face of a frame member having a bonding material thereon into contact with the bonding material, bonding the first or second substrate opposite to the face of the frame member having the bonding material thereon and the frame member to each other, by irradiating a laser beam to the bonding material through at least a underlying layer. Here, the underlying layer includes a material which absorbs the laser beam easily, and the laser beam is irradiated to a predetermined range. Thus, in bonding of base materials by irradiation of the laser beam, it is possible to reduce damages such as occurrence of disconnection and short circuit in wirings, and achieve reliability and excellent airtightness of the image display apparatus. | 03-17-2011 |
20110061806 | MANUFACTURING METHOD OF IMAGE DISPLAY APPARATUS, AND BONDING METHOD OF BASE MATERIALS - A method comprises: arranging a bonding material between a pair of base materials; and bonding, as mutually pressing the pair of the base materials, the pair of the base materials by the bonding material, by irradiating an electromagnetic wave while moving an irradiation position along the bonding material to melt and then harden the bonding material, wherein the arranging includes arranging the bonding material on one of faces of the pair of the base materials so as to have a convex portion which continuously extends in a direction along which the bonding material extends and in which its central region in a width direction protrudes toward the other of the faces of the pair of the base materials. Thus, a stress according to heating and cooling of the base material is reduced and crack does not occur easily in a bonding portion. | 03-17-2011 |
