1. An image display including a display panel having an enclosure comprising:
- a front substrate having a phosphor layer and an anode electrode;
a rear substrate that has electron sources and faces the front substrate with a predetermined gap therebetween; and
a frame disposed around a display area and between the front substrate and the rear substrate, wherein the display panel has an opening configured such that the distance between the front substrate and the rear substrate increases toward the periphery of the display panel, and a frame member whose height decreases toward the inside of the display panel is fit into the opening for airtight sealing.

Abstract
A display panel has an evacuation port at one side thereof, and the opening area of the evacuation port increases toward the periphery of the display panel. The display panel also has a frame member in the opening, and the height of the frame member lowers toward the inside of the display panel. According to the invention, by improving the evacuation efficiency in the airtight container and improving the vacuum level in the display panel in a short period of time, the electron emission characteristic is stabilized and the lifetime thereof is increased, allowing a high-quality, reliable image display to be provided.

7. An image display comprising an enclosure comprising a first substrate on which electron emission elements are formed, a second substrate on which a phosphor surface is formed and a frame that connects the first substrate to the second substrate, the enclosure being evacuated,
wherein the first substrate includes a plurality of scan lines that extend in a first direction and are arranged in a second direction that crosses the first direction as well as a plurality of data lines that extend in the second direction and are arranged in the first direction, first electrodes connected to the scan lines and second electrodes connected to the data lines forming the electron emission elements, and at least one of the surface of the frame that faces the first substrate and the surface of the frame that faces the second substrate is an inclined surface that inclines to the plane formed by the first and second directions, the height of the surface of the frame disposed outside the enclosure being higher than the height of the surface of the frame disposed inside the enclosure.
