AI Technical Summary

Problems solved by technology

If the encapsulant cracks, the substrates will naturally not be sealed together, and the encapsulant and sublayer may be destroyed by the crack
In many cases, the substrate itself is also damaged, making it difficult to recycle and reuse these substrates
Therefore, there arises new problems that the success rate of the sealing process decreases and it is difficult to efficiently manufacture a satisfactory image display device.

Embodiment Construction

[0030] Embodiments in which a display device according to the present invention is applied to a FED will now be described with reference to the drawings.

[0031] like Figures 1 to 4 As shown, the FED includes a front substrate 11 and a rear substrate 12, each of which is composed of a rectangular glass substrate and functions as a first and a second substrate, respectively. These substrates are arranged facing each other with a given interval. The rear substrate 12 is formed to have a larger size than the front substrate 11 . The front substrate 11 and the rear substrate 12 are connected together at their respective peripheral portions with side walls 18 in the form of rectangular frames, thereby forming a flat rectangular vacuum envelope 10 that keeps the inner space at high vacuum.

[0032] A plurality of plate-shaped supporting members 14 are provided in the vacuum-sealed housing 10 so as to support atmospheric loads acting on the front substrate 11 and the rear substra...

Abstract

A front substrate (11) and a rear substrate that are oppositely arranged with a gap in between are sealingly adhered at a predetermined position by an adhering section (33), defining a sealed space between the substrates. The adhering section has a base layer (31a, 31b) formed on the inner surface of at least either of the substrates and has an adhesive layer (32) made from an adhesive material and formed on the base layer. The thickness of the base layer is from 5 mum to 22 mum.

Description

technical field [0001] The present invention relates to an image display device having two substrates disposed opposite to each other and a sealing portion sealing the substrates together and a method of manufacturing the same. Background technique [0002] In recent years, various flat image display devices have been evaluated as next-generation lightweight, thin display devices to replace cathode ray tubes (hereinafter referred to as CRTs). These image display devices include liquid crystal displays (hereinafter referred to as LCDs), plasma displays (hereinafter referred to as PDPs), field emission flat panel display devices (hereinafter referred to as FEDs), surface conduction electron emission devices (hereinafter referred to as SEDs), and )wait. LCDs use the alignment of liquid crystals to control the intensity of light. The PDP uses ultraviolet rays generated by plasma discharge to excite phosphors to emit light. FEDs use electron beams from field emission electron ...
