摘要： A shadow mask includes a perforated region in which a plurality of electron beam passage apertures are formed, a non-perforated region on the periphery of the perforated region, and a skirt portion bent to an electron gun side with respect to the non-perforated region. The curved surfaces on an x-axis and a y-axis of the perforated region are convex to a panel side. The perforated region includes a curved surface that is convex to the panel side and a curved surface that is convex to the electron gun side on a periphery of the perforated region. Furthermore, the perforated region has a curved surface that is convex to the panel side and a curved surface that is convex to the electron gun side in a region surrounded by the periphery, the x-axis, and the y-axis. Because of this, the color displacement caused by doming can be reduced while a shadow mask is used which is made of an inexpensive iron material, and in which the increase in the difference in elevation in the z-axis direction between a center portion and a diagonal portion of the perforated region is suppressed.

摘要： A substantially rectangular shadow mask in a dome shape includes a plurality of tie-bands with a longitudinal direction thereof being a short-side direction of the shadow mask, a plurality of bridges connecting the tie-bands adjacent to each other in a long-side direction of the shadow mask, and a plurality of electron beam passage apertures formed between the tie-bands. In a region sandwiched by a pair of straight lines parallel to the long-side direction, which respectively pass through a pair of the bridges adjacent to each other in the short-side direction, on a surface of the tie-band on a side opposed to a panel, a plurality of non-through concave portions are formed. Consequently, color displacement caused by heat doming of the shadow mask can be suppressed.

摘要： To provide an image display apparatus in which provision of a mechanical mechanism is not required for reducing an effect of a speckle noise that is generated when a coherent light is used as a light source and a noise can be suppressed. An image display apparatus (1) changes phase of a light emitted from a light source device (a laser light source device (10) including laser light sources (10a to 10c) for each of R, G, and B colors is shown as a sample) at high speed by a phase change portion including an electro-optical crystal (phase change portions (12a to 12c) corresponding to each laser are shown as a sample). Therefore, because an interference pattern on a screen (16) changes at high speed and it is averaged by the human eye, the speckle noise can be reduced.
