Abstract
A hermetically sealed container includes a front substrate, a back substrate disposed opposite to the front substrate, and an outer frame disposed in a peripheral portion between the front substrate and the back substrate. The front and back substrates and the outer frame are bonded with an adhesive to form a hermetically sealed space. When a ratio W/T of width W and thickness of T of the outer frame is set to an aspect ratio A of the outer frame, 1.5≦A.
Claims16
An image forming apparatus using a hermetically sealed container comprising:
- a front substrate provided with an image forming member and a conductive film;
- a back substrate disposed opposite to said front substrate and provided with an electron source;
- and
- an outer frame disposed between said front substrate and said back substrate, with said front substrate, said back substrate, and said outer frame being bonded with an adhesive to form a hermetically sealed space, with said adhesive arranged between said outer frame and said front substrate and between said outer frame and said back substrate, wherein
- when a ratio W/T of width W and thickness of T of said outer frame is set to an aspect ratio A of said outer frame, 1.5≦A, with the width W measured in a direction substantially parallel with planar surfaces of said front and back substrate, and T being in a range 1-10 mm.
