摘要:
An image display apparatus comprises, in a vacuum container formed by a rear container (10) and a front glass container (14), a fluorescent layer (15), an electron emission source (11c), electrodes (11,12,13) to control electron beams emitted from the electron emission source (11c). The electrodes (11,12,13) are formed by stringing wires (11b,12b,13b,13c) on frames (11a,12a,13a) made of a resilient material, and the frames (11a,12a,13a) on which the wires (11b,12b,13b,13c) are strung have respectively pairs of opposing sides that are flat plates formed on the same surface. The electrodes that are free from waviness or warping have high flatness, control the focusing and deflection of the electron beams appropriately, and prevent deviation of the landing positions of the electron beams and errors including error irradiation. Such an image display apparatus can provide excellent images and high resolution.
