  • Publication number: 20110130065
    Abstract: A method for producing a display is provided, the method comprising a step of adhering a light-transmissive substrate, wherein it is possible to suppress the occurrence of any bubble when the light-transmissive substrate is adhered to a display surface, even when the display surface is large-sized. A plurality of adhesive puddles 3 are formed in an area which is disposed on a first light-transmissive substrate 1 and which is opposed to an adhesive puddle 4 formed on a second light-transmissive substrate 2. The spacing distance between the first and second light-transmissive substrates 1, 2 is narrowed while allowing the first and second light-transmissive substrates 1, 2 to be opposed to one another, and a space between the both is filled with the adhesive.

  • Patent number: 7794299
    Abstract: A method for manufacturing an image display device includes the steps of preparing a plurality of spacers preliminarily, measuring heights of the plurality of spacers prepared by the preparing step individually, and deciding an order of arranging the spacers on the basis of the measured heights obtained in the measuring step. The spacers are arranged in the order decided in the deciding step.

  • Patent number: 7659554
    Abstract: A hermetic container includes a first substrate, a second substrate opposed to the first substrate, a frame arranged between the first substrate and the second substrate, and a composite member arranged between the first substrate and the second substrate. The frame is composed of a frame member, a first seal bonding material effecting seal bonding between the frame member and the first substrate, and a second seal bonding material effecting seal bonding between the frame member and the second substrate. The composite member is composed of a first member, a first adhesive material bonding the first member and the first substrate to each other, and a second adhesive material bonding the first member and the second substrate to each other.

  • Patent number: 7453197
    Abstract: A display apparatus having a first plate-shaped member having plural electron-emitting devices which are dispersively distributed and a second plate-shaped member having a plurality of light-emitting members arranged on a surface which faces the first plate-shaped member in correspondence to the plural electron-emitting devices, in which in at least either the first plate-shaped member or the second plate-shaped member, directions of normal lines extending from the plural electron-emitting devices or the plural light-emitting members are distributed in a tendency. A pitch of arranging the adjacent electron-emitting devices and a pitch of arranging the light-emitting members corresponding to the adjacent electron-emitting devices are different in accordance with the distribution of the normal-line directions.
