摘要:
An image display apparatus includes: an electron-emitting electrode having a gate electrode a cathode electrode including a plurality of strip portions opposing to the gate electrode through a gap, wherein each gap functions as an electron emitting portion when a potential difference between a gate potential and a cathode potential is applied to the each gap; and a light-emitting member emitting light responsive to an irradiation with electrons emitted from an electron emitting portion. The plurality of the strip portions of the cathode electrode are arranged in a line along a predetermined direction. Intervals each between mutually adjacent strip portions of the cathode electrode are arranged such that the interval in a central region of the electron emitting portions is larger than that in a peripheral region thereof.
