    摘要: In an image display apparatus which has a multi-electron beam source in which a plurality of electron emission elements are connected in a matrix pattern using a plurality of data electrodes and a plurality of scanning electrodes, and a fluorescent screen having phosphors of three primary colors R, G, and B corresponding to the electron emission elements, natural white color emission is obtained while suppressing a decrease in G luminance, using, e.g., a checkerboard layout which has a G spatial resolution higher than the R or B spatial resolution and includes more G phosphors than the R or B phosphors. For this purpose, the scanning electrodes connected to the electron emission elements corresponding to the G phosphors are electrically independent from those connected to the electron emission elements corresponding to the R or B phosphors, signal components corresponding to the G phosphors and signal components corresponding to the R or B phosphors are extracted from an image signal for a 1-line period, and the scanning electrode connected to the electron emission elements corresponding to the G phosphors and those connected to the electron emission elements corresponding to the R or B phosphors are selected during successively the 1-line period.

    摘要: This invention has as its object to easily form a low-cost spacer having a low-resistance film (electrode) without using any exhaust device. This invention provides a method of manufacturing a spacer interposed between the first substrate having an image forming member and the second substrate having an electron-emitting device, including the steps of preparing a glass preform, stretching part of the glass preform while heating the glass preform by a heater, and cutting the stretched glass preform into a desired length, wherein the stretching step has the step of feeding the glass preform at a velocity v1 toward the heater, and stretching the glass preform heated by the heater in a direction away from the heater at a velocity v2, and the velocities v1 and v2 have different speeds and satisfy a relation: v1
