Abstract: In a manufacturing method for an image display device, one of a pair of substrates is provided with a reinforcing member, these substrates are located opposite each other with the reinforcing member and a space therebetween, the pair of opposed substrates are heated, the pair of substrates are then cooled in a manner such that the space between the pair of substrates is narrower than the space for the heating operation and that radiant heat from the other substrate is applied to the reinforcing member, and respective peripheral edge portions of the pair of cooled substrates are sealed together.

Abstract: When manufacturing a vacuum enclosure of an image display unit, degassing is performed by baking a back-side substrate provided with a plurality of strip-like slender spacer in a standing state. In this time, radiant heat is applied to the upper side of the spacer, to prevent the radiant heat reaching the side of the spacer, and to prevent an increase in a temperature difference between the spacer and back-side substrate.

Abstract: A cathode ray tube phosphor screen inspecting method includes the steps of illuminating a panel of a cathode ray tube, in which a phosphor screen having a regular pattern is formed the inner surface of a face, from the inner surface of the face, imaging the face inner surface, and specifying a defect on the phosphor screen from data obtained by the imaging. The panel, an illuminating unit for illumination, and an image unit for performing the imaging are moved relative to each other. The amount of light from the illuminating unit is changed in accordance with this relative movement.

Abstract: An exposure apparatus for exposing a phosphor screen of a cathode ray tube includes a light source portion having an elongate light source lamp and a shading member arranged to face the lamp. The shading member is formed with a slit through which a light beam from the lamp passes. The slit is formed in a V-shaped configuration in which it protrudes toward the light source lamp. The shading member is formed such that a cross section thereof in the direction in parallel to the axis of the light source lamp has a wedge-like shape in which the thickness increases from the edge of the slit toward the end thereof in the direction of the axis, and such that a cross section in a direction perpendicular to the axis has a uniform thickness at the position of the slit.
