Publication number: 20110130065Abstract: 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.Type: ApplicationFiled: November 24, 2010Publication date: June 2, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Tomokazu Andoh, Tomoyuki Tamura, Shintarou Akiba, Haruo Tomono, Kazuya Morohashi

Patent number: 7794299Abstract: 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.Type: GrantFiled: May 20, 2008Date of Patent: September 14, 2010Assignee: Canon Kabushiki KaishaInventors: Makoto Kanda, Masahiro Tagawa, Tomokazu Andoh, Takahiro Oguchi

Patent number: 7453197Abstract: 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.Type: GrantFiled: December 15, 2005Date of Patent: November 18, 2008Assignee: Canon Kabushiki KaishaInventor: Tomokazu Andoh
